Pepperrell and Warren at length came to an understanding as to a joint attack by land and water. The Island Battery was by this time crippled, and the town batteries that commanded the interior of the harbor were nearly destroyed. It was agreed that Warren, whose squadron was now increased by recent arrivals to eleven ships, besides the provincial cruisers, should enter the harbor with the first fair wind, cannonade the town and attack it in boats, while Pepperrell stormed it from the land side. Warren was to hoist a Dutch flag under his pennant, at his main-top-gallant mast-head, as a signal that he was about to sail in; and Pepperrell was to answer by three columns of smoke, marching at the same time towards the walls with drums beating and colors flying. [Footnote: Warren to Pepperrell, 11 June, 1745. Pepperrell to Warren, 13 June, 1745.]
The French saw with dismay a large quantity of fascines carried to the foot of the glacis, ready to fill the ditch, and their scouts came in with reports that more than a thousand scaling-ladders were lying behind the ridge of the nearest hill. Toil, loss of sleep, and the stifling air of the casemates, in which they were forced to take refuge, had sapped the strength of the besieged. The town was a ruin; only one house was untouched by shot or shell. "We could have borne all this," writes the Intendant, Bigot; "but the scarcity of powder, the loss of the 'Vigilant,' the presence of the squadron, and the absence of any news from Marin, who had been ordered to join us with his Canadians and Indians, spread terror among troops and inhabitants. The townspeople said that they did not want to be put to the sword, and were not strong enough to resist a general assault." [Footnote: Bigot au Ministre, 1 Août, 1745.] On the 15th of June they brought a petition to Duchambon, begging him to capitulate. [Footnote: Duchambon au Ministre, 2 Sept. 1745.]
On that day Captain Sherburn, at the advanced battery, wrote in his diary: "By 12 o'clock we had got all our platforms laid, embrazures mended, guns in order, shot in place, cartridges ready, dined, gunners quartered, matches lighted to return their last favours, when we heard their drums beat a parley; and soon appeared a flag of truce, which I received midway between our battery and their walls, conducted the officer to Green Hill, and delivered him to Colonel Richman [Richmond]."
La Perelle, the French officer, delivered a note from Duchambon, directed to both Pepperrell and Warren, and asking for a suspension of arms to enable him to draw up proposals for capitulation. [Footnote: Duchambon à Pepperrell et Warren, 26 Juin (new style), 1745.] Warren chanced to be on shore when the note came; and the two commanders answered jointly that it had come in good time, as they had just resolved on a general attack, and that they would give the Governor till eight o'clock of the next morning to make his proposals. [Footnote: Warren and Pepperrell to Duchambon, 15 June, 1745.]
They came in due time, but were of such a nature that Pepperrell refused to listen to them, and sent back Bonaventure, the officer who brought them, with counter-proposals. These were the terms which Duchambon had rejected on the 7th of May, with added conditions; as, among others, that no officer, soldier, or inhabitant of Louisbourg should bear arms against the King of England or any of his allies for the space of a year. Duchambon stipulated, as the condition of his acceptance, that his troops should march out of the fortress with their arms and colors. [Footnote: Duchambon à Warren et Pepperrell, 27 Juin (new style), 1745.] To this both the English commanders consented, Warren observing to Pepperrell "the uncertainty of our affairs, that depend so much on wind and weather, makes it necessary not to stickle at trifles." [Footnote: Pepperrell to Warren, 16 June, 1745, Warren to Pepperrell, 16 June, 1745.] The articles were signed on both sides, and on the 17th the ships sailed peacefully into the harbor, while Pepperrell with a part of his ragged army entered the south gate of the town.
"Never was a place more mal'd [mauled] with cannon and shells," he writes to Shirley; "neither have I red in History of any troops behaving with greater courage. We gave them about nine thousand cannon-balls and six hundred bombs." [Footnote: Pepperrell to Shirley, 18 June (old style,) 1745. Ibid., 4 July, 1745.] Thus this unique military performance ended in complete and astonishing success.
According to English accounts, the French had lost about three hundred men during the siege; but their real loss seems to have been not much above a third of that number. On the side of the besiegers, the deaths from all causes were only a hundred and thirty, about thirty of which were from disease. The French used their muskets to good purpose; but their mortar practice was bad, and close as was the advanced battery to their walls, they often failed to hit it, while the ground on both sides of it looked like a ploughed field, from the bursting of their shells. Their surrender was largely determined by want of ammunition, as, according to one account, the French had but thirty-seven barrels of gunpowder left, [Footnote: Habitant de Louisbourg.]—in which particular the besiegers fared little better. [Footnote: Pepperrell more than once complains of a total want of both powder and balls. Warren writes to him on May 29th: "It is very lucky that we could spare you some powder; I am told you had not a grain left.">[
The New England men had been full of confidence in the result of the proposed assault, and a French writer says that the timely capitulation saved Louisbourg from a terrible catastrophe; [Footnote: "C'est par une protection visible de la Providence que nous avons prévenu une journée qui nous auroit été si funeste." Lettre d'un Habitant de Louisbourg.] yet, ill-armed and disorderly as the besiegers were, it may be doubted whether the quiet ending of the siege was not as fortunate for them as for their foes. The discouragement of the French was increased by greatly exaggerated ideas of the force of the "Bastonnais." The Habitant de Louisbourg places the land-force alone at eight or nine thousand men, and Duchambon reports to the minister D'Argenson that he was attacked in all by thirteen thousand. His mortifying position was a sharp temptation to exaggerate; but his conduct can only be explained by a belief that the force of his enemy was far greater than it was in fact.
Warren thought that the proposed assault would succeed, and wrote to Pepperrell that he hoped they would "soon keep a good house together, and give the Ladys of Louisbourg a Gallant Ball." [Footnote: Warren to Pepperrell, 10 June, 1745.] During his visit to the camp on the day when the flag of truce came out, he made a speech to the New England soldiers, exhorting them to behave like true Englishmen; at which they cheered lustily. Making a visit to the Grand Battery on the same day, he won high favor with the regiment stationed there by the gift of a hogshead of rum to drink his health.
Whether Warren's "gallant ball" ever took place in Louisbourg does not clearly appear. Pepperrell, on his part, celebrated the victory by a dinner to the commodore and his officers. As the redoubtable Parson Moody was the general's chaplain and the oldest man in the army, he expected to ask a blessing at the board, and was, in fact, invited to do so,—to the great concern of those who knew his habitual prolixity, and dreaded its effect on the guests. At the same time, not one of them dared rasp his irritable temper by any suggestion of brevity; and hence they came in terror to the feast, expecting an invocation of a good half-hour, ended by open revolt of the hungry Britons; when, to their surprise and relief, Moody said: "Good Lord, we have so much to thank thee for, that time will be too short, and we must leave it for eternity. Bless our food and fellowship upon this joyful occasion, for the sake of Christ our Lord, Amen." And with that he sat down. [Footnote: Collection of Mass. Hist. Society. I. 49]
