Their work was still unfinished when the Iroquois were upon them again. They had broken to pieces the birch canoes of the French and their allies, and kindling the bark, rushed up to pile it blazing against the palisade; but so brisk and steady a fire met them that they recoiled, and at last gave way. Again and again, however, they came on, each time leaving many of their bravest fighters dead upon the ground. At length, their spirits dashed, the warriors drew back. A canoe was hastily sent down the river to call to their aid five hundred Iroquois who were mustered near the mouth of the Richelieu. Meanwhile, the defenders of the fort were harassed night and day with a spattering fire and a constant menace of attack. Thus five days passed. Hunger, thirst, and want of sleep wrought fatally on the strength of the French and their allies, who, pent up together in a narrow prison, fought and prayed by turns. Deprived as they were of water, they could not swallow the crushed Indian corn which was their only food. Some of them, under cover of a brisk fire, ran down to the river and filled such small vessels as they had. But this meagre supply only tantalised their thirst, and they now dug a hole in the fort, to be rewarded at last by a little muddy water oozing through the clay. On the fifth day an uproar of unearthly yells from seven hundred savage throats, mingled with a clattering salute of musketry, told the Frenchmen that the expected reinforcement had come. Soon a crowd of warriors mustered for the attack. Cautiously they advanced, screeching, leaping, and firing as they came on; but the French were at their posts, and every loophole darted its tongue of fire. Besides muskets, they had heavy musketoons of large calibre, which, scattering scraps of lead and iron among the throng of savages, often maimed several of them at one discharge. The Iroquois, astonished at the persistent vigour of the defence, fell back discomfited. The fire of the French had told upon them with deadly effect. Three days more wore away in a series of futile attacks; and during all this time Daulac and his men, reeling with exhaustion, fought and prayed, sure of a martyr's reward.
