A tremendous shock now shook the fort, as a camarade battery of ten 32-pounders commenced a discharge against it, and showers of destructive bombbelles from small mortars were poured into the heart of the place. Many of these little engines of destruction bounded from the shingle roofs of the barracks and burst in the waters of the lake; others were exploding in all directions, with a sound like the roar of artillery, forcing the soldiers, who crept and cowered in rear of the parapets and palisades, to lie close, while the heavy _hum_ of the round shot, with that peculiar sound which terminates its course by piercing the ground, or crashing through a building, and the sharper _whish_ of the musket-balls, filled up all the intervals by noises fraught with alarm. The barracks and storehouses were soon unroofed and ruined, for the camarade battery proved very destructive; the stockades were soon swept away in showers of white splinters before its discharges, which resembled nothing but a whirlwind of shot and shell, while vast masses of the earthen works were also torn down, leaving the defenders exposed to the deadly rifles of the lurking Indians. The cannon of Munro were alike defective and dangerous to his soldiers; for two 18-pounders, two 32-pounders, and two 9-pounders burst in succession, destroying all who were near them, and at last the colonel received intimation that only seventeen bombs remained in the magazine. On the _sixth_ day, there was still no appearance of General Daniel Webb (who was Colonel of the 48th, or Northamptonshire Foot), though his column was within hearing of the firing, being at Fort Edward, which was only six miles distant; and now the spirit of the garrison began to sink; but in that dejected band there was no heart more heavy than MacGillivray's, for the condition of his wife at such a terrible crisis filled him with the deepest anxiety and the most tender solicitude. At last Munro, finding the futility of further resisting forces so overwhelming, and that all hope of succour from Webb was hopeless, on the 9th day of August, 1757, lowered his standard, and sent forth MacGillivray to the French camp, bearer of a flag of truce, to confer on the terms of a surrender.
