A Campaign of Amateurs: The Siege of Louisbourg, 1745
by Raymond F Baker
The Siege
The provincial army made no regular approaches to Louisbourg by
trenches, but bombarded the town at random from the Green Hill and Royal
batteries, as well as from additional batteries erected between 18 and
31 May. Except for the Royal Battery, all of these works were fascine
batteries, protected by fagots of various dimensions made of small tree
branches or brush. In some cases, as with the Advanced Battery near the
Dauphin Gate (see "The Advance Batteries"), they also may have
been protected by hogsheads filled with earth. The batteries were
reinforced by earth banked against the fascines, but in only one
instance that of a trench dug at the Advanced Battery were
they entrenched works, in the sense of being dug below actual ground
level. They were all sited to the northwest and north of the fortress,
because the marshy ground to the southeast precluded the construction of
works in that sector. Shirley was aware that several years previously
the French had built a gallery toward Green Hill beneath the glacis
opposite the flanked angle of the King's Bastion. He instructed
Pepperrell not to construct batteries and trenches between Green Hill
and the King's Bastion, "as the glacis that lies there before the works
is to be blown up."1 It is significant to note that no works
were made in this vicinity through the entire siege, even though the
gallery did not extend beyond the glacis itself.
The Provincial Batteries, their Effects, and French
Countermeasures
Royal Battery
By 20 May, the gunners at the Royal Battery had been trying for
nearly a week to breach the walls of the fortress, but with little
success. Through the efforts of Major Seth Pomeroy and 20 "smiths," who
were assigned the task on 16 May, some 20 cannon had now been cleared.
While only four embrasures pointed against the town, Waldo reported that
241 shot had been fired from the Royal Battery between 14 and 20 May.
The French return fire from the town and island batteries amounted to
some 417 shot and shell.2
During this time, the fire from the Royal Battery had reportedly
destroyed the roofs of three houses and knocked down several chimneys,
as well as a number of embrasures of one of the bastions, probably the
Dauphin. It was also reported that earlier, on 14 May, several shots had
penetrated the roof of the barracks. Some of the shots fired from the
Royal Battery struck short of the town, glanced off the water, and
ricocheted over the walls.3
The French return fire against the Royal Battery during this period
and throughout the siege, while at times heavy and on occasion
continuing both day and night, lacked effect and caused comparatively
little damage. The towers, however, did sustain heavy damage, but only
one man was killed and only a few were wounded by the French
fire.4
The greatest danger came not from the French counterfire but from the
provincial gunners themselves, who, in moments of zealousness coupled
with inexperience, overcharged the cannon and caused them to explode. On
16 May, one of the cannon was accidentally double-shotted, blew up and
severely wounded five men, including Captain Rhodes, the chief gunner.
The next day two more cannon burst, probably from the same cause. And
again on 27 May, two cannon exploded from double-shotting and wounded
two men, one of them Captain Daniel Hale, the man upon whom, after
Rhodes, Waldo was most dependent to work the guns.5
Waldo's great concern over this practice of double-shotting is
revealed in his letter of 31 May to Pepperrell, in which he regretted
the loss of the cannon but feared that all of the guns were in danger of
the same fate "unless better regulation [is provided] than at present."
The next attempt, he said, would probably be the "trying of three shott
in each, which they will increase till they find their mistake . . . ."
Waldo was also plagued by food and powder shortages as well as lacking
trained gunners, conditions that would persist and prove troublesome
throughout the siege.6
(It might be noted here that the Royal Battery served several
functions in addition to being a siege battery: it was a base supplying
cannon to new batteries; a point from which, after 21 May, attacks on
the Island Battery were launched, and a base from which scouting parties
and patrols could operate.)7
Coehorn Battery
The Coehorn Battery had been erected by order of the 16 May war
council and probably was sustained by men from Richmond's regiment. The
gunners at this work were as zealous as those at the Royal Battery in
trying to open a breach in the fortress wall. Located beyond a small
pond northwest of the King's Bastion, the Coehorn Battery began to fire
on 22 May and until the day of the surrender "n'a point Cessé de tirer
des Boullets sur Les Casernes, Le mur du Bastion du Roy of Sur la ville."
The shot raked the streets as far as the Maurepas Gate and the
crenellated wall, and damaged the barracks and the right flank of the
King's Bastion. No one was safe, in either the street or the houses. The
barracks were ruined by this fire, along with several
houses.8
To counteract the fire from the Coehorn Battery, which Duchambon
considered by far the most dangerous of the provincial batteries, the
French placed two 18-pounders on a cavalier of the King's Bastion.
Soldiers worked hurriedly and under fire to fill two wooden frames
(coffres en planches) with fascines and earth to form embrasures
for the guns and to afford a measure of protection to the gunners. At
the same time, they opened two embrasures in the parapet of the right
face of the King's Bastion, where two 24-pounders were
mounted.9 When these measures were taken is not clear, but
the work was probably done before the Advanced Battery on the heights
opposite the Dauphin Demi-bastion began to fire on 29 May.

These measures did little to hinder or reduce the fire from the
Coehorn Battery; French counterfire proved equally ineffectual and the
damage it sustained from French shot was minor compared to the damage it
inflicted on the walls and town. The damage suffered by the Coehorn
Battery was the possibly accidental breaking of the trunnion on one of
the mortars, and the wounding of six men (one of whom died) on 24 May by
the bursting of two 22-pounders. One man was killed and two were wounded
by French fire. On 5 June, the 13-inch mortar burst, "occasion'd by some
Flaw in the Shell, which broke in the Mortar," and a gunner was wounded.
Another 13-inch mortar was brought from Boston and mounted eight days
later.10
The Advance Batteries
On 25 May the ring of provincial batteries around Louisbourg
tightened further when the New Englanders raised a battery of four guns
on a hill within 440 yards of the Dauphin Gate. The coehorns and the 9-
and 11-inch mortars from the Coehorn Battery were removed to this work.
Three days later, on 28 May, the provincials raised another battery in
the same area, within approximately 250 yards of the Dauphin Gate.
Although the New Englanders referred to both works as advance batteries,
the latter was most commonly called the "Advanced" Battery. It was
commanded by Captain Joseph Sherburne of Moore's New Hampshire Regiment.
The work consisted of two 18-pounders and two 42-pounders brought from
the Royal Battery, "upwards of two Miles, as the Road goes, over a
rough, rocky, hilly way." The Advanced Battery, the more effective of
the two works, was located on the rise of ground (known to the French as
the Montagne à Francoeur) at the end of the glacis of the Dauphin
Demi-bastion. It began to fire on 29 May, although only one 18-pounder
had as yet been mounted. Colonel Vaughan later stated that he "staked
out the Ground [for the Advanced Battery] with his own Hands, &
directed Trench to be thrown up sufficient to cover a thousand Men
adjoining the Fascine [Advanced] Battery & fronting the City," and
that here he "continued four successive Days and Nights doing Duty and
undergoing excessive Fatigues, scarce allowing himself common
Refreshments."11
Between 23 and 28 May, as a countermeasure against the advance
batteries then in preparation on the heights, the French blocked up the
Dauphin Gate and the adjoining guardhouses with about 18 to 20
feet of freestone, fascines and earth. Duchambon later stated that had
this not been done, the provincials could have entered through the gate
immediately after the advance batteries opened fire, claiming that the
walls of the gate were only about three feet thick and no stronger than
a porte-cochère (carriage gate). Nor, he added, were the sides of
the gate protected, the only defence consisting of créneaux on
the guardhouse which could not be used once they had been reinforced
with earth.12
To hinder further the preparation of the advance batteries, Duchambon
ordered his men to construct some embrasures for the four cannon on the
barbette of the Dauphin Demi-bastion, on the soldiers' guardhouse. They
made these embrasures of sod and earth, as there was no time to make
them of stone. Duchambon also said that the flanks of all the bastions
of the fortress were supplied with the cannon from privateers and any
other ordnance that could be found in the town.13
Once the advance batteries opened fire, Duchambon reported, they
never ceased firing until the surrender, despite continual French
counterfire from the cannon on the barbette of the Dauphin Demi-bastion
and from those of the right flank of the King's Bastion. Captain
Sherburne stated that his post, the Advanced Battery, was so poorly
entrenched that "the most Shelter we had from the french fire (which was
very hott) was Some hhds [hogsheads] filled with earth." The fire of the
advance batteries was concentrated on the Dauphin Gate, in an attempt to
open a breach in that section of the wall. A number of flakes (frames
for drying fish) lay between the gate and the advance batteries, and the
provincial gunners "was forst to Beat them away with out Shott to have a
fair Sight of the Gate."14
The French soldiers at the Dauphin Demi-bastion annoyed the gunners
at the Advanced Battery with musket fire. That battery was so near the
walls that "there was no safety in loading the Cannon, but under the
fire of the Musquetry, which was very smart on both Sides." The French
"generally open'd the Action in the Morning with the Fire of their
Small-Arms for two hours; which we returned with Advantage on our Side."
Five provincials were killed the first day, two by musket balls and
three by cannon shot. One of those killed by cannon shot was Captain
Joshua Pierce.15
The gunners at the advance batteries were "warmly entertained" by
French cannon fire from a flank of the Pièce de la Grave, as well
as from the cannon at the Dauphin Gate and the right flank of the King's
Bastion. To provide still more effective fire, the French cut three
embrasures in the King's-Dauphin curtain, where they mounted 36-pounder
cannon. These embrasures were opened on 30 May. The guns, on the first
day, demolished the embrasures of the Advanced Battery and dismounted
one of its cannon, but the provincial fire went unabated and continued
to wreak havoc on the buildings of the town. Among others, the houses of
Messrs. Fautoux, Carrerot, Fizel, Gilbert and Prévost were badly damaged
or destroyed. A shot broke the fortress bell, and the chapel was so
badly riddled that the Récollet friars abandoned it and thereafter held
daily services in the hospital. When the powder magazine in the Dauphin
Demi-bastion became endangered, Duchambon ordered the powder removed to
the postern in the curtain wall between the King's and Queen's bastions.
He also ordered his men to destroy the drawbridge by cannon shot. The
flag staff was shot away on 9 June.16
On 31 May, the New Englanders dug a trench at the south end of the
Advanced Battery and mounted an 18-pounder and two 9-pounders there. The
fire from these guns and those of the Coehorn Battery was concentrated
on the King's Bastion (the fire from which flanked the Advanced Battery)
where several cannon were dismounted and the cannoneers forced to
abandon the guns. This fire so "annoyed" the French "that they were
silent the rest of the day." On 3 June, the French mounted two new guns
on the right flank of the King's Bastion, but the shot from the advance
batteries was so heavy that they abandoned them after only four
hours.17
Because much damage was being done to the King's Bastion, the French
cut new embrasures in the parapet of the Dauphin Demi-bastion near the
gate on 17 June to provide increased counterfire. Two cannon were
mounted there, and "soon began to play with great Fury; and [the
provincials] were obliged to turn Three Guns against them." In three
hours, reportedly, one of the French cannon was dismounted and the other
silenced.18
Occasionally the fire would slacken and the men at the Advanced
Battery, which was closest to the fortress walls, bantered with the
French. One such incident occurred on the morning of 1 June. The New
Englanders called out to the French soldiers at the Dauphin Demi-bastion
that if they would send out a flag of truce, they could have some of
"King George's bread" to eat. The French replied that they were not yet
ready to surrender, nor did they wish any of the king's bread. Other
conversation followed, the provincials asking if there were any "Pritty
girls" in the town; but the interlude was finished off "with 3 or 4
showers of bullets" on both sides.19
While the gunners at the advance batteries inflicted much damage on
the town and fortifications, they sustained a minimum loss themselves,
suffering a total of 10 men killed and 15 or 16 wounded, several by
musket balls. The damage done to the entrenchments or the batteries
during the day the New Englanders quickly repaired during the
night.20
Titcomb's Battery
On 31 May, the provincials raised a fifth battery on the northwestern
shore of the harbour (on what the French called the hauteur de
Martissans) across a small bay known as the Barachois,
approximately 800 yards from the Dauphin Gate. This battery called
Titcomb's Battery after its commander, Major Moses Titcomb of Hale's
reigment, whose men largely sustained the work, initially mounted two
42-pounders (three more 42-pounders were later added) drawn from the
Royal Battery, and was designed expressly to bombard the Dauphin Gate
and the circular battery of the Dauphin Demi-bastion.21
Titcomb's Battery opened fire on 31 May. That same day its cannon
knocked down the guérite and part of the salient angle of the
Dauphin Demi-bastion. The éperon near the gate, which the French
had already repaired several times with freestone and earth, was
demolished to the height of its embrasures. The cannon of the Advanced
Battery were fired in support of Titcomb's, and the shot soon smashed
the embrasures as well, and also broke through the quay wall and
dismantled its embrasures. The concentrated fire from the two batteries
completely demolished the Dauphin Gate, pounded a breach in the wall of
the Dauphin Demi-bastion to within 10 feet of the bottom of the ditch,
and severely damaged the circular battery. Major General Wolcott
recorded that by 17 June, the shot had
broken down the top of the West [Dauphin] gate and the wall nigh
it, as low as the glacis, and dismounted the guns at that place, and
dismounted all the guns in the circular battery except three, many of
the embrasures being broken to pieces and the wall in a shattered
condition below, and damaged a small battery below it: they had likewise
dismounted the guns planted on [the King's Bastion] at the north-west
end of the citadel, the embrasures and wall being very much shattered
and broken.22
The fire from Titcomb's and the advanced batteries demolished the
embrasures on the right flank of the King's Bastion (where the French
had mounted six 18- and 24-pounders). Duchambon ordered his soldiers to
construct some contre-merlons and wooden embrasures, and while
this task was completed on 19 June and the cannon once more put to use,
the embrasures were again soon smashed.23
On 15 June the provincials had given the French defenders of
Louisbourg an added terror by firing red-hot shot from their mortars.
The French, using some type of fire-fighting device, acted swiftly to
extinguish fires in several houses, and otherwise managed to contain
what might have proven a holocaust.24
Other Measures Taken by the French
Despite constant counterfire from the cannon of the King's Bastion,
the Dauphin Demi-bastion, and the Pièce de la Grave, plus musket
fire from the walls and such places as the breach in the Dauphin Gate
and the adjoining guardhouses, the provincial batteries continued to
rain destruction on the fortress. Fearing the New Englanders would
attack the town by landing in barges along the quay, Duchambon ordered
his men to construct a floating barricade of masts (estacade de
mâts) from the éperon of the Dauphin Demi-bastion as far as
the Pièce de la Grave. The French began the barricade about 31
May and completed it on 11 June. The soldiers who built it worked under
constant fire from the provincial batteries.25
Fearing an assault through the breach in the Dauphin Demi-bastion,
Duchambon ordered chief engineer Verrier to have an entrenchment built
across the breach from which to defend it. This entrenchment, which
stretched from the quay to the parapet at the front of the Dauphin, was
finished on 24 June, the French doing much of the construction work at
night.26
Also, at some point during the siege, the French raised an
épaulement of dry stone at the king's bakery, and established a
corps de garde for the militia.27
But no matter what measures were taken, they were not enough. By 26
June, further resistance would seem useless. "Never was a place so
mauled with cannon and shells," Pepperrell would write after the
capitulation. He estimated that the provincial batteries had fired into
the town about 9,000 cannon shot and 600 mortar bombs. The destruction
was tremendous. The streets were rent from end to end, and every
building and all of the houses save one were damaged or destroyed and
unfit for habitation. The right flank of the King's Bastion no longer
existed, except as a pile of rubble, and the King's-Dauphin curtain was
riddled with shot. The Dauphin Demi-bastion had taken the brunt of the
cannonade and was badly pummeled: the Dauphin Gate had been reduced to a
gaping breach; the newly cut embrasures had been knocked to pieces; all
but three of the guns at the circular battery had been dismounted and
the wall of the battery itself beaten down. The éperon was
completely dismantled, as were the embrasures along the
quay.28 The French powder supplies were nearing exhaustion,
and the garrison waited anxiously for the attack that was sure to come
through the breach at the Dauphin.
French Morale and the Capture of the Vigilant (30 May)
Despite the fatigues and devastation that each day brought, the
garrison and residents of Louisbourg displayed a remarkable
determination to withstand the onslaught made against them. They worked
untiringly to clear the debris from the ramparts so the cannon might
still be used. Children, 10 and 12 years of age, bore arms and stood to
the walls with the soldiers, "exposing themselves with a courage beyond
their years." There were exceptions, however, and deserters reported to
the provincials that some of the regular soldiers were succumbing to the
mounting pressures. They desired to surrender and would often refuse
their duties; these disagreements, it was said, even led to frequent
duels, one of which some provincial soldiers saw from a tower of the
Royal Battery. Several Swiss soldiers managed to escape, and on 19 June
a French soldier attempted to get out of the town with a letter from a
captured provincial to his friends, but was discovered and immediately
hanged. Yet most of the soldiers and residents seem to have resolved to
hold out to the last extremity,29 this despite fitful and
sleepless nights on the ramparts and in the casemates; with, reportedly,
no meat left in the town and a diet of fish, bread and
peas;30 with their powder nearly exhausted, and their last
hope of succour gone with the capture of the Vigilant.
The spirits of the defenders of Louisbourg were badly shaken by the
capture of the 64-gun French man-of-war, the Vigilant, upon which
they had relied heavily for relief. The Vigilant, manned by 500
sailors and commanded by Captain de La Maisonfort, sailed from Brest on
26 April with orders to get into Louisbourg harbour and help defend the
place. Word had been received that the English were going to attack.
(Only one French ship, a snow, had been able to get into the harbour
since the provincial landing and she carried only supplies for the
fishermen.) Should Louisbourg be blockaded, La Maisonfort was instructed
to do what he could to help without needlessly endangering his ship. The
Vigilant was laden with stores for the garrison, a large number
of cannon, and a great quantity of much-needed powder. She also,
reportedly, carried 20 chests of small-arms, as well as stores and
rigging for a privateer then being fitted out at
Quebec.31
According to the habitant de Louisbourg, the Vigilant
came in view of the fortress on 28 or 29 May, about a league and a half
distant from Scatarie Island, with a good northeast wind for her
destination. The Bristish blockading squadron was at least two and a
half leagues to leeward, and if seemed the Vigilant would be able
to slip into Louisbourg harbour without difficulty. But about noon on 30
May, La Maisonfort spotted the English ship Mermaid (40 guns),
Captain Douglass commanding, close in-shore and gave chase, hoisting the
French flag and pennant as he closed.32
The Mermaid's stern gun opened on the Vigilant and
Douglass signalled the rest of the fleet that he had sighted a strange
ship. The Vigilant replied to the Mermaid with a shot from
her bow cannon, and the fight was on. At 2 o'clock, La Maisonfort
discovered the remainder of Warren's squadron closing from the northward
and, giving the Mermaid a broadside in passing, hoisted full sail
and bore off to the southward. Douglass gave chase, and for the next
four hours gave broadside for broadside. At about 6 o'clock, Captain
Rous in the Shirley galley joined the Mermaid and gave the
Vigilant a shot from his bow gun. The Eltham joined at 7
o'clock and Warren in the Superbe fell in an hour later. At 9
o'clock, La Maisonfort asked for quarter. The Vigilant's rigging,
masts and yards were badly damaged, and the ship itself was
unserviceable. Sixty of her crew of 500 were killed or
wounded.33 The French were transferred to the British
ships.
The next day, 31 May, Warren notified Pepperrell of the capture,
advising him that he intended "to Commission [the ship] for his
Majesty"; and hoped that Pepperrell would be able to furnish a crew to
man her. He also told Pepperrell that as the Vigilant had been
"much shattered" in the engagement, he was sending her into Gabarus Bay
for repairs and refitting, "and beg that you will direct vessels to come
to take the Prisoners from us . . . [as] otherwise the Cruizers will be
useless, with such numbers on board." Warren hoped that the capture of
the Vigilant "will be a very happy event, for our further
success."34
The Vigilant's fate was far from a "happy event" for the
French. "Témoins de sa manoeuvre," wrote the habitant, "il
n'étoit personne de nous qui ne donnât des malédictions à une manoeuvre
si mal concertée & si imprudente." While La Maisonfort had displayed
great courage in the engagement,
mais il auroit mieux valu qu'il eût suivi sa destination; c'étoit
tout ce que les intérêts du Roi exigeoient. Le Ministre ne l'envoyoit
pas pour donner la chasse à aucun Vaisseau ennemi: chargé de munitions
de guerre & de bouche, son Vaisseau étoit uniquement destiné a
ravitailler notre malheureuse Place, qui n'auroit jamais été en effet
emportée, si nous eussions pû recevoir un si grand secours; mais nous
étions des victimes devouées à la colere du Ciel, qui a voulu faire
servir contre nous jusqu'à nos propres forces.35
The loss of the Vigilant "ralentit le courage de ceux qui
avoient le plus conservé de fermeté, . . . et plusieurs personnes furent
d'avis qu'il falloit dèslors demander à capituler."36 But the
fortress held out.
To say that Louisbourg would not have fallen had the Vigilant
passed through Warren's blockade is debatable. There are arguments for
both sides of the question. The siege would have been prolonged in any
case. La Maisonfort's spirited sailors would have greatly cheered the
defenders and perhaps have instilled in them added determination to
resist; the cannon and powder the Vigilant carried would have
been of great use to the garrison; and the broadsides of her 64 guns
would have made it very uncomfortable for the provincial gunners at the
Royal and advance batteries. But the key to the Louisbourg defences was
still the Island Battery, and it would probably have been only a matter
of time before the provincials erected a battery to counter the fire
from that work. Then Warren's fleet could enter the harbour and, though
the British squadron would have to come one at a time through the narrow
north channel, neither the Vigilant's 64 guns nor the
determination of seamen would have much effect against the broadsides of
11 battleships, each averaging from 40 to 60 cannon.
The supply of powder on board the Vigilant would now be used
by the besiegers, however, and, noted the habitant, "nous nous
apperçûmes que leur feu avoit depuis beaucoup augmenté."37
The Attacks on the Island Battery (18 May6 June)
French spirits were raised temporarily on 6 June, when the garrison
of the Island Battery aborted a provincial attack on that post. The
Island Battery, a strong fortification defended by about 200 men and 36
cannon under command of d'Ailleboust stood defiantly in the middle of
the harbour entrance, and was the only obstacle preventing Warren's
squadron from entering and raking the fortress from the harbour. The
provincial commanders feared that the town might not be taken unless the
fleet could get into the harbour and the fortress be bombarded from land
and sea.38 The abortive assault of 6 June was the culminating
effort of several planned attacks on the island stronghold.
As early as 18 May, immediately following Duchambon's refusal to
surrender the town, a council of war advised that an attack be made on
the Island Battery. Commodore Warren brought a number of seamen ashore
to assist, and that night about 800 men, including Colonel Gorham's
regiment, were to set out for Gabarus Bay. The whaleboats, however,
were late in coming and because of high surf and approaching daylight,
the attempt was cancelled. Similar attempts were planned on 19 and 20
May, but these were also cancelled, probably because of high surf. The
New Englanders apparently wearied of trying to attack the island by sea,
believing that the waters of the harbour afforded a safer approach,
because on 21 May the whaleboats were carried overland from Gabarus Bay
to the Royal Battery, whence an attack was planned for that night.
Warren and his seamen were still on shore to participate, but again the
attack was called off.39
On 22 May, Colonel Vaughan proposed that he be allowed to organize an
attempt, but nothing came of his proposal. Warren, who for several days
had been on shore to participate in the proposed attacks, ordered his
seamen back on the ships on 23 May. The commodore himself returned to
the Superbe "not a little dissatisfied."40
Not until 2 June were plans again made for attacking the Island
Battery, and the whaleboats were again prepared for use. About 150 men
carried additional boats from Gabarus Bay, "which was the Hardest
Service I've Ever Undergone in all my Life," wrote one soldier, "(and So
Said they all) but having a Prospect thereby to take the Island Battery
made us Chearfully Endure our burden." Despite the men's exertions, the
attempt was cancelled, "oweing to the moon & the northern lights,"
and because the men who showed up for the attack were without officers
and "in liquor."41
Yet another attack, this one much better organized, was prepared
for the night of 3 June. That day, Colonel Waldo sent two of his
captains to visit other regiments to find suitable volunteers for the
project. In a letter to Pepperrell, Waldo said that Major Thatcher of
Gorham's regiment had 15 men, including himself, willing to take part,
but that he was having difficulty obtaining cooperation from Hale's
regiment. Hale's men were using their work on the new Titcomb's Battery
as an excuse for not taking part. Waldo, however, did manage to "detach"
several unwilling volunteers from Hale and wanted to get 50 or 100
more. He also felt that the services of Captain John Card's company (of
Moulton's regiment), Elder Harnar's company (of Pepperrell's regiment),
and Captain Terry's men (of Willard's regiment) would be particularly
useful. Commodore Warren wrote Pepperrell that he hoped to be able to
provide upwards of 200 seamen for the attempt.42
Exactly which units took part in the 3 June attempt has not been
determined, but all day a great number of men were busy preparing
paddles and ladders for "near fifty" whaleboats, and at about midnight
some 500 men of the army and fleet embarked for the island. They were
commanded by Lieutenant Colonel Arthur Noble of Waldo's regiment and
Colonel John Gorham.43
When the provincials set off from the Royal Battery, their course
was illuminated by a "Remarkable Northern Twilight;" but by the time
they drew near the island a dense fog had rolled in and they could not
see where to land. The assault was then called off. Colonel Noble's
conduct in the affair was called into question, and Seth Pomeroy, the
gunsmith, claimed that Noble could not be found at the time the attack
got under way. Pomeroy implied that the volunteers went without him and
that "For want of an officer the Soldiers Return'd." The rumour of
Noble's negligence persisted and the next day a council of war examined
the charges. The council, however, found no grounds to accuse either
Noble or Gorham of misconduct in the affair.44
The council also announced "that if a number of men to the amount of
three or four hundred appear as volunteers for [another] attack of the
Island Battery, they be allowed to choose their own officers and be
entitled to the plunder found there." The prospect of plunder brought
about 400 men together on 6 June. They selected Captain (Edward?) Brooks
to lead them. Pepperrell's secretary, Green, directed that all pistols
in Hale's regiment be turned over to the men volunteering for the
attack. As the men assembled at the Royal Battery, Captain Sherburne at
the Advanced Battery prepared to support them with diversionary fire
from his cannon. The night was cool and foggy and there was a very high
surf. At midnight the men climbed into the boats and rowed toward the
island but, Seth Pomeroy wrote, "Providence Seemed Remarkable to Frown
upon the affair." They were discovered before all the troops could be
landed.45
As the provincials began to disembark at the island, somebody yelled
"Hurrah!" and the alarm went up. Some New Englanders later believed
that the French had been warned of the attack and were waiting in
ambush. The French gunners loaded their cannon with langrage, pointed
them toward the whaleboats and opened fire, causing much disorder and
confusion among the provincials but apparently doing little damage. Many
of the boats were cut off by the cannon fire and turned back, but four
or five beached on the island and the men scrambled ashore, firing their
muskets and pistols at the shadowy figures on the walls above them. Some
of the small arms misfired, the powder being soaked by the mist and by
the high surf as the men jumped ashore. Several of the provincials
hauled ladders from the boats and placed them against the walls, the men
all the while under heavy musket fire from the ramparts above.
Duchambon reported later that the commandant, d'Ailleboust, along with
the governor's son and an ensign, de La Pérelle, were the first to climb
upon the ramparts to fire on the New Englanders, and that their men
urged them to get back from the walls and not expose
themselves.46
For two hours, the small-arms fighting continued at close quarters.
Then, the situation hopeless, the provincials broke and ran for the
boats. But the tide had carried off many of the boats and there were not
enough left to accommodate all of the men. The remaining boats were soon
filled, probably overloaded. Cannon shot cut one of them in half as it
was pushed off from the island, the men drowning in the surf. The
provincials in the other boats would not come to their rescue for fear
they too would be sunk by cannon fire.47
Some of the men went ashore at Lighthouse Point, while others made it
back to the Royal Battery to carry news of the debacle to Pepperrell.
"Now things lookt something dark," wrote Green. The provincial losses
were about 60 men killed and from 112 to 119 captured. Some of the dead
washed up on shore at the lighthouse; some of the wounded had to have
limbs amputated.48
"Wee have great Reason to be humble'd before God," wrote one diarist,
and the next day the batteries for a time were strangely silent. "From
all accounts," wrote the Reverend Joseph Emerson, "we learn the men are
prodigiously discouraged."49
The French, however, were cheered by the result of this encounter.
They had only three men killed or wounded, and the repulse of the
provincials at the Island Battery was the only real success they had
experienced since the siege began. Duchambon, perhaps unwittingly,
exaggerated the numbers of the provincials, reporting that 1,000
soldiers in 35 barges, with 800 reinforcments, had been driven in panic
from the island that night.50
To Pepperrell, the repulse at the Island Battery was doubly
unfortunate, for he could ill afford the loss of so many soldiers. His
army was sick with dysentery, or what was then called the "bloody
fluxes," brought on by fatigue, lack of proper food, and poor and
unsanitary living conditions. During this period at least 1,500 men were
unfit for duty. For days Pepperrell had been appealing to Shirley and
the other New England governors to send more men, but he could not count
on their arriving for some time yet. The troops were becoming
demoralized, and the defeat at the Island Battery only added to the
general despair. One volunteer wrote to his father that "I am sorry to
find our New England troops . . . want to go home, home, is all ye cry
& [they all say] if I was well at home I'd engage they should never
find me such a fool again this is the language of those who are
as well used as can be." It is hardly surprising that Pepperrell wrote
on 13 June that "I apprehend no further attempts will be made on [the
Island Battery] by boats."51
Friction Grows Between the Provincial Commanders
The Island Battery had to be silenced if Warren's squadron was to
help, and Warren himself was growing impatient. He was far from
satisfied with the seemingly inactive role the navy had played blocking
the harbour against French ships, and he complained that he was tired of
doing nothing.
On 4 June, Warren had sent a plan ashore for Pepperrell's review and
approval. The plan had already been approved by Warren's ships'
captains. It proposed that the Vigilant be fitted out and manned
by 600 landsmen; that 1,000 men from the army embark on the other
vessels of the squadron; that the harbour be forced; and that a vigorous
attack on the town be made by boats from the ships. A council of war
called on 5 June "maturely considered" Warren's plan and, in effect,
rejected it on several grounds: there was too much sickness in the army
and the men could not be spared; Pepperrell had learned that Duchambon
had sent for Marin's detachment of French and Indians and the men must
be kept at hand to meet that contingent when it arrived; the men, being
unused to the sea, would soon be unfit for service by being kept on
board the ships. In time, the council advised, a concerted action would
be arranged, but not at the present.52
The council's decision did little to alleviate Warren's impatience,
and on 6 June he wrote brusquely to Pepperrell
For God's sake, let us do something and not waste our time in
indolence. I sincerely wish you all the honour and success imaginable
and only beg to know in what manner I can be more serviceable, that in
cruizing, to prevent the introduction of succours to the garrison. I
fear that if that be all that is expected from the ships, or that they
can do, Louisbourg will be safe for some time; for my part I have
proposed all that I think can be done already, and only wait for your
answer thereto.53
Pepperrell's reply, which did not come until 8 June, was hardly
calculated to placate the anxious Warren for it dealt, at some length,
only with the army and its condition. The troops, Pepperrell wrote, had
in just 29 days
erected five fascine batteries, and . . . with 16 pieces of
cannon, and our mortars mounted at said batteries, and with our cannon
from the royal battery, we have been playing on the town, by which we
have greatly distrest the inhabitants, made some breaches in the wall,
especially at the west gate, which we have beat down, and made a
considerable breach there, and doubt not but shall soon reduce the
circular battery. That in this time we have made five unsuccessful
attempts upon the island battery, in the last of which we lost about 189
men, and many of our boats were shot to pieces, and many of our men
drowned before they could land; that we have also kept out scouts to
destroy any settlements of the enemy near us, and prevent a surprise in
our camp . . . that by the services aforesaid and the constant guards
kept night and day around the camp, at our batteries, the army is very
much fatigued, and sickness prevails among us, to that degree that we
now have but 2100 effective men, six hundred of which are gone in the
quest of two bodies of French and Indians [one of which was thought to
be that of Marin's] we are informed are gathering, one to the eastward,
and the other to the westward.54
The commodore would have to wait. The council had decided not to make
any more attacks against the Island Battery, and Warren's officers
advised that it was not practicable for the fleet to try to enter the
harbour until that battery was silenced.55
The Erection of the Lighthouse Battery (12-21 June)
On 12 June, the provincials decided to erect a battery at Lighthouse
Point opposite the Island Battery about 3,400 feet distant. The final
decision to erect the battery came only after the repeated failures to
take the Island Battery pointed up the need for such a work. Waldo on 6
June had urged Pepperell to erect a work there, and Warren on 12 June
likewise pressed Pepperell to "hasten the battery at the lighthouse"
because the pilots thought it "impossible to go in [to the harbour] till
[the Island Battery] can be silenced."56
Pepperrell told Warren that the battery would soon be completed, that
"there are three embrasures facing the Island Battery, and six facing
the sea," and that he hoped to have the cannon mounted there in two
days. Transporting the cannon must have proved more of a difficulty than
Pepperrell had anticipated, because it was nearly eight days before the
guns were mounted. The New Englanders carried them by boat from Gabarus
Bay to a point about a mile and a quarter east of the lighthouse, where
they dragged them up the steep cliffs along the shoreline. By 21 June,
they had mounted two 18-pounders (four were mounted on 25 June). The
"great mortar" was also carried to the lighthouse and mounted. The
battery was sustained by 320 men of Gorham's regiment.57
A number of provincials (possibly Gorham's regiment) had been
stationed for some time on the lighthouse side of the harbour in
anticipation of erecting a battery there. Duchambon knew of their
presence, and a Lieutenant Vallée of the artillery company had informed
him that several 18- and 24-pounders, some still serviceable, had been
buried at the careening wharf near the lighthouse some ten years
previously to serve as piles (corps-morts). Duchambon feared that
the provincials would find the guns and use them to equip a battery
against the island. Unknown to the French, the New Englanders had
already found these cannon. But on the night of 27 May the French
commander set a detachment of about 100 local men and militia as well as
some privateers under Beaubassin, to try to prevent the provincials from
setting up a battery on that side of the harbour.58
Beaubassin and his men set out in three chaloupes, with food
for 10 to 12 days and 30 to 50 rounds of ammunition. They reached Grande
Lorembec that night, came ashore, and the following morning encountered
about 40 provincial soldiers near the lighthouse. The New Englanders
were prepared (Bigot asserted they had been warned by a fisherman who
had deserted from Beaubassin) and a sharp skirmish resulted. The French
failed to press their numerical advantage, panicked, and retreated into
the woods. Many, being near their homes and not wishing to be confined
again inside the fortress, deserted. Others in the rush threw their
supplies away and returned to the town, hungry and tired, several days
later. The provincials reportedly suffered no casualties in the fight
and the French loss was three men killed and several wounded. Dudley
Bradstreet recorded that a French captain who was mortally wounded and
taken prisoner offered 10,000 pounds (livres?) for a priest to
pardon his sins. Mockingly, Bradstreet asserted that he would have been
willing to do this himself, and for half the money.59
The Lighthouse Battery was finished and opened fire on the Island
Battery on 21 June. The shot swept the west platform of the French
fortification and prevented the gunners from working the cannon. When
the large mortar began to fire, 17 out of 19 shells reportedly fell
within the work, one of them upon the magazine. "And this together with
the Fire from our Cannon, to which the enemy was very much exposed, they
having but little to shelter 'em from the Shott, which rang'd quite
thro' their Line of Barracks, so terrified 'em that many left the Fort
and ran into the Water for Refuge." The provincial fire soon knocked
holes in the barracks and the bakery (both of which had been reinforced
with wood from the store of a M. Dacarrette), nearly ruining these
buildings. The French responded to the bombardment, but the Lighthouse
Battery was so placed that they could not bring an effective counterfire
against it.60 The Island Battery was rapidly becoming
untenable, and it was only a matter of time before Warren's fleet would
be free to enter the harbour.
The Proposed Assault of 26 June and the Surrender of Louisbourg
The time was not long in coming. By 26 June the New Englanders had
readied a general assault by land and sea. Between 21 and 26 June Warren
and Pepperrell had been in constant correspondence with each other and
had held numerous joint councils. The records of the correspondence and
councils between the two commanders indicate that, of the two, Warren
was the more anxious for the attack, while Pepperrell, mindful of the
disastrous results of the 6 June attack on the Island Battery, relied
more upon the siege guns to gradually wear down the French
defences.61
The Lighthouse Battery was effectively reducing the Island Battery,
and Warren was able to win Pepperrell over to the scheme for a combined
attack on the fortress. The preparations for the attack had been
completed. The fleet, now numbering 11 warships and several armed New
England vessels, had been cleared for action; the spare timbers and
masts had been removed and the decks barricaded with moss as protection
against small-arms fire. Six hundred men of the army supplemented the
crews of the warships. Provision for three large beacon fires had been
made on three hills west of the fortress. When ignited, these fires
would serve as guides for Warren's ships as they entered the harbour,
possibly indicating that a night attack had been planned. Ladders and
fascines for filling the ditch and scaling the walls had been carried to
the Advanced Battery, where Captain Sherburne by 12 noon had "got all
our platforms Laid, ambrazures mended, Guns in Order, Stock of
Cartridges, Shot in Place, Gunners Quartered, Dined, & matches Lit,"
ready for the signal to attack. Commodore Warren was on shore and the
troops drawn up on parade heard him proclaim that "He'd Rather Leave his
Body at Louisbourg, than not take the Citty." Everyone was ready; all
that was needed now was a favourable wind.62
The French in Louisbourg looked apprehensively on the preparations
for the assault they knew they could not withstand. By 26 June they were
dispirited and fatigued from the rigorous defence they had made, from
much work and no sleep. Now they began to question whether further
resistance was justified. The Island Battery was a shambles; its fire
was slack and ineffective and would no longer keep the enemy fleet out
of the harbour. The town was in ruins, the fortifications were breached,
and of the 1,300 men who had undertaken the defence of the fortress,
nearly 50 had been killed, another 80 to 95 had been severely wounded,
and several had succumbed to utter exhaustion. Reportedly the French had
not changed their clothes since the day the provincials landed in
Gabarus Bay.63 The capture of the Vigilant had removed
all hope of succour, and Duchambon had heard nothing from Marin's
detachment, which he had sent for on 16 May. It was a time of great
despair, and the habitant wrote that "Les Conseils étoient plus
fréquens que jamais. . .; on s'assembloit sans trop savoir pourquoi,
aussi ne sçavoit-on que résoudre." He continued,
J'ai souvent ri de ces assemblées, oû il ne se passoit rien que de
ridicule & qui n'annonçât le trouble & l'indecision. Le soin de
notre défense n'étoit plus ce qui occupoit. Si les Anglais eussent sçu
profiter de notre épouvante, il y auroit eu long-tems qu'ils nous
auroient emportés, l'épée à la main. Mais il faut convenir à leur
louange qu'ils avoient autant de peur que nous.64
Now it seemed that the English were no longer afraid, and while the
soldiers might be willing to fight on, the residents had had enough. On
the morning of 26 June they petitioned Duchambon to surrender. They
pointed out that since the enemy force both on land and on sea was
increasing daily, and since the French had obtained no aid and could not
hope to defeat the New Englanders, Duchambon and his officers should ask
for terms so the residents might keep what little property remained to
them. Duchambon asked Verrier to report on the state of the
fortifications; he made a similar request of Sainte-Marie about the
status of the ammunition. These reports were rendered and a council of
war was called, the members voting unanimously that, because of the
growing enemy force and the condition of the fortifications,
ammunition, and town, it would be best to capitulate.65 After
the council's decision, Duchambon composed the following note to
Pepperrell and Warren:
Desirous of putting a stop to acts of hostility; and prevent the
effusion of blood on one side and on the other, I send you an officer of
our garrison to deliver you the present [letter], in order to desire on
you a suspension of arms, for so long a time as shall be needful for me
to make proposals to you, upon the conditions of which I shall determine
to deliver up to you, the place which the King my master has entrusted
me with.66
Ensign de La Pérelle, who had recovered from a wound received during
the 6 June attack on the Island Battery, was designated to carry the
letter to the provincial commanders. At 4 o'clock in the afternoon, the
ensign appeared at the Dauphin Gate under a flag of truce. He was met
halfway between the gate and the Advanced Battery by Captain Sherburne,
who then escorted him to Colonel Richmond at Green Hill. There he was
either met by or taken to Pepperrell and Warren, to whom he handed over
Duchambon's letter. The provincial commanders granted Duchambon until 8
o'clock the next morning (27 June) to present the terms upon which he
would surrender the fortress.67 A general cessation of
hostilities was called.
Duchambon submitted his terms between 8 and 9 o'clock on the morning
of 27 June. These terms, carried to the provincial lines by
Bonnaventure, were not accepted by Pepperrell and Warren, who then sent
in their own terms for the capitulation (see Appendix D). The
articles were basically the same as those contained in the summons of 18
May: that the inhabitants and their effects would be transported to
France and, if needed, vessels would be provided for the purpose; that
the officers and inhabitants would be permitted to remain in their
houses and enjoy freedom of religion without molestation; that the
non-commissioned officers and soldiers would be placed on board British
ships and transported to France; that the sick and wounded would be
cared for; that two covered wagons could be sent off under the
inspection of only one provincial officer who would search only for
war-like stores, and that anyone who so desired might go off
masked.68 This last condition was one that Duchambon
initially asked for and raises the suspicion that, for various reasons,
there were persons in the fortress who wanted to leave without being
seen perhaps a New Englander who had deserted to the French, or a
privateer or contraband merchant who might have been recognized by
certain members of the provincial army.
In return for these terms, the governor was to see that the surrender
took place as soon as possible, that the Island Battery or some other
battery, along with all its artillery and ammunition, was turned over to
provincial soldiers that day, that Warren's fleet was permitted to enter
the harbour unmolested, that officers, soldiers, and residents of the
fortress would not take up arms against the English for 12 months, and
that all British subjects then in the town were immediately delivered
up.69 These conditions were to be met by 6 o'clock that
evening, or the provincials threatened to "decide the matter with our
arms."
The terms made no allowance for the "honours of war," that is, the
troops being permitted to march out bearing arms, with drums beating and
flags unfurled, and Duchambon refused to consider them unless that
provision was included. He wrote two letters, one to Pepperrell and
another to Warren, saying that he could not allow the troops to leave
the fortress without these honours, that they were honours due to
soldiers who had done their duty, and that once the provincial
commanders agreed to that provision, he would agree to the
rest.70
On 28 June Pepperrell informed Duchambon that both he and Warren
would allow the French troops to march out with the honours of war. The
officers and other inhabitants, he wrote, should repair to their houses
where they would be safe, and the arms should be put in a safe magazine
and would be turned over to the French soldiers the day they marched out
of town. With this, Duchambon accepted the terms and formally ended the
siege of Louisbourg.
The siege had lasted 47 days, and the number of casualties sustained
on either side seems incredibly low. The French claimed that 50 men had
been killed and from 80 to 95 severely wounded, while the provincial
losses were estimated at 100 men killed by the French and 30 others who
had died of sickness.71 No mention of the number of wounded
has been found.
The Island Battery was delivered up to Warren by M. de Gannes on the
morning of 28 June, and the English colours were raised on the
flagstaff. At 2 o'clock that afternoon, Warren entered Louisbourg
harbour at the head of his squadron, "which made a beautiful
Appearance." When the ships were sufficiently moored, a broadside salute
was fired and the soldiers and sailors gave three
cheers.72
At 4 o'clock, several regiments of the army advanced toward the town
to take possession. At the head of the column marched Colonel John
Bradstreet, followed by Pepperrell and his officers. They entered
through the Queen's Gate and, as the New Englanders moved toward the
parade ground where the French were drawn up in order, Girard La Croix
noted the flags flying, the drums beating, and the odd combination of
sound offered by the trumpets, flutes and violins that accompanied the
tread of the victorious provincials. The French men and women who
watched "looked very sorrowful," one witness remarked. At the parade
ground, the officers of the two armies exchanged the usual salutes,
"every Part being performed with all the Decency and Decorum
imaginable," and the town was officially surrendered.73
Guards were posted to prevent looting, but they had little effect.
The New Englanders, decried the habitant, "contre la foi dûe à
notre capitulation . . . se jetterent dans nos Maisons & y ont Pris
tout ce qui les accommodoit." Bigot also accused the provincials of
"beaucoup de pillage et d'insultes" to the inhabitants after the
surrender.74 But there was no recourse against the
violators.
Conclusions
The outcome of the siege both surprised and shocked French officials
in Paris who found it difficult to understand how an amateur army of
undisciplined volunteers could capture the "strongest" French fortress
in North America. The New Englanders, however, who from the beginning
were supremely confident of success, were not at all surprised at the
outcome. They had come to capture Louisbourg and this they had done; it
was as simple as that. If asked for specific reasons for their success,
however, most of them probably would not have been able to respond
adequately. Many attributed success to the will of God, of whom they
were the instrument designed to rid the continent of a great "Stronghold
of Satan." Others would not know why they had succeeded, but thought it
was "the most glorious and useful thing done in the
war."75
Obviously, the reasons for the New England victory at Louisbourg go
far beyond the simple explanation that it was the "will of God," and,
indeed, beyond any single factor. In searching for answers to the
question it is useful to recall the words of Captain H.F. Thullier,
R.E., who, in his book The Principles of Land Defence (1902),
cautioned:
Nothing is more difficult than to correctly analyse the causes of
success or failure in the attack and defence of fortresses in past
times. The reason of this is that the causes are, as a rule, very
complex There are a great number of conditions which enter into each
case, and many, or all of them, may have had a bearing on the result.
The activity of the garrison, the organization of the defence, the
ability and resolution of the commander, the relative power of the
ordnance, the sufficiency of the supplies, all these and many other
causes may have important effects upon the results of sieges; and also
the fate of the fortresses is often influenced by the tactical methods
and energy of the attackers, as well as by external strategic
considerations, such as the movements of other bodies of troops
elsewhere. It is seldom too that complete data on these heads are
available, so wrong conclusions are often arrived at on this account. It
therefore often happens that a false importance is given to one or
other of the conditions in a particular case, and wrong deductions are
made from the erroneous premise thus set up. It is thus seldom safe to
seize upon particular events and deduce therefrom particular
theories.76
With this admonition in mind, a few of the more patent factors that
contributed to the provincial success might be suggested. Among these
factors must be placed the provincial occupation of the Royal Battery
early in the siege. Possession of this battery not only gave the New
Englanders effective control of the inner harbour but it also provided
them with a much-needed supply of serviceable heavy calibre cannon, left
behind when the French abandoned the battery. The New Englanders never
adequately utilized their control of the harbour to launch an attack by
water against the town (although several attacks were directed against
the Island Battery), but the surplus cannon were used to strengthen the
armament of the several batteries raised against the fortress.
Other factors were, first, the erection of the Advanced and Titcomb's
batteries, and then, near the close of the siege, the erection of the
Lighthouse Battery. Pepperrell and his officers, though ignorant of the
fine points in the art of siegecraft, clearly realized the necessity of
effecting a breach in the fortress walls before the place could be
taken. The Green Hill Battery, raised soon after the landing, was of
little use in this respect because of the excessive range. The Coehorn
Battery, composed mostly of mortars, proved equally ineffective on the
fortifications, although it did cause great destruction to the interior
of the town. Not until the Advanced and Titcomb's batteries were formed,
mainly of cannon removed from the Royal Battery, were the New Englanders
able to greatly neutralize the French defence and breach the walls, thus
preparing the way for a land assault.
Perhaps the French could have withstood a land assault. The erection
of the Lighthouse Battery, however, soon added another dimension to the
threat an attack by sea. One of the key works in the French
defence system was the Island Battery, standing athwart the harbour
entrance and effectively barring the entry of the British fleet. Both
Warren and Pepperrell feared that success would not be assured until the
Island Battery was rendered impotent and the ships were permitted to
enter the harbour for a combined land and sea assault on the town.
Pepperrell was slow to realize the need for the Lighthouse Battery,
preferring initially to launch boat attacks against the island
stronghold. Not until the abortive attack of 6 June did he concede the
folly of such strategy and push forward the completion of the Lighthouse
Battery.
The New Englanders soon realized the value of that battery. After
only two days of firing, it effectively silenced the Island Battery.
Duchambon must have known that while a land attack might be repulsed, a
combined land and sea assault could prove disastrous. He could not risk
subjecting the inhabitants and garrison to the destruction such an
attack would bring. Surrender seemed the only course open to him.
The importance of the Advanced, Titcomb's, and Lighthouse batteries
cannot be over-emphasized. Without them, ultimate success would surely
have been delayed and perhaps lost. Samuel Waldo was forcibly impressed
by the contribution these works made to the reduction of Louisbourg, and
on 7 November 1757, he advised Secretary of State William Pitt of the
great benefits to be derived from the erection of similar batteries,
should England contemplate another attack on the
fortress.77
Of equal, if not greater, significance was Louisbourg's very poor
defensive position. Surrounded on the landward side by dominating
heights, its security would be threatened by an enemy occupying those
heights. The French seem to have given little serious consideration to
the dangers thus posed, nor, indeed, to the prospect of an enemy attack
at all. If they had given serious thought to preparing an adequate
defence, they might have constructed outworks to retard or prevent an
enemy from occupying the high ground north and west of the fortress.
Although some works apparently were projected, none was constructed.
The French should have been particularly concerned about the rise of
ground located about 250 yards northwest of the glacis at the Dauphin
Demi-bastion and known to them as the Montagne à Francoeur. This
height was a very commanding position and posed great dangers to the
fortifications in this sector. An enemy battery situated on this hill
could quite easily breach the walls. The French should have placed an
outwork on this height to prevent it being occupied, or, at the very
least, should have levelled it to diminish the advantage it would afford
an enemy. Neither of these expedients was taken. The provincials soon
raised here the Advanced Battery and effected the breach in the Dauphin
Demi-bastion that opened the way for a land assault.
Duchambon recognized early that to withstand a siege he would have to
have some form of external relief. With very few exceptions, as the
history of siege warfare reveals, no fortress has been able to resist a
resolute besieging army indefinitely without some form of external aid.
To quote Captain Thullier again:
However strong the works and powerful the armament, however
complete the organization and ample the supplies, a fortress will never,
if invested by superior and resolute forces, be able to achieve its own
delivrance without external help. This external help may take the form
of an army advancing to its relief by driving off the besiegers, or it
may be the effect of successful strategical action in other parts of the
theatre of war, which results in the withdrawal of the assailing force;
but failing these it is absolutely necessary that the external
communications of the fortress should be kept open so that fresh
supplies and munitions can be received. Without this it is a mere
question of time till the garrison are forced to lay down their arms
from starvation or lack of cartridges. On the other hand, with open
communications there is no reason why a properly defended fortress
should not be able to hold out for an indefinite time against a greatly
superior force.78
Early in the siege Duchambon doubted his ability to withstand a siege
with the force under his immediate command and sent for Marin's
detachment to come and drive off the New Englanders. Marin, however,
failed to arrive in time. With supplies of food and powder dwindling
rapidly and the situation looking bleaker each day, the French attached
great hope to the arrival of the Vigilant for the much-needed
relief. But Warren's fleet had effectively blockaded Louisbourg's sea
communications and captured the Vigilant before she reached her
destination. Her capture doomed Louisbourg's chances for relief. With no
hope for a successful outcome of the contest, the inhabitants petitioned
Duchambon to surrender.
The war between Britain and France did not end with the capture of
Louisbourg; it continued for another three years. But the Louisbourg
campaign was the most significant and dramatic event of the war in the
North American theatre of operations. At the peace conference in 1748
England returned Louisbourg to France, much to the anger and protests of
the New England colonies. In 1758, during the Seven Years' War, the
French fortress was again besieged, this time by regular troops of the
British army. It is significant that the pattern of operations during
the siege of 1758 very closely paralleled those carried out 13 years
earlier. Perhaps the provincials were not such amateurs after all.
