A third attack was now determined on, though some of Howe's officers remonstrated, declaring it would be downright butchery. A different plan was adopted. Instead of advancing in front of the redoubt, it was to be taken in flank on the left, where the open space between the breastwork and the fortified fence presented a weak point. It having been accidentally discovered that the ammunition of the Americans was nearly expended, preparations were made to carry the works at the point of the bayonet; and the soldiery threw off their knapsacks, and some even their coats, to be more light for action. General Howe, with the main body, now made a feint of attacking the fortified fence; but, while a part of his force was thus engaged, the rest brought some of the field-pieces to enfilade the breastwork on the left of the redoubt. A raking fire soon drove the Americans out of this exposed place into the enclosure. Much damage, too, was done in the latter by balls which entered the sallyport. The troops were now led on to assail the works; those who flinched were, as before, goaded on by the swords of the officers. The Americans again reserved their fire until their assailants were close at hand, and then made a murderous volley, by which several officers were laid low, and General Howe himself was wounded in the foot. The British soldiery this time likewise reserved their fire and rushed on with fixed bayonet. Clinton and Pigot had reached the southern and eastern sides of the redoubt, and it was now assailed on three sides at once. Prescott ordered those who had no bayonets to retire to the back part of the redoubt and fire on the enemy as they showed themselves on the parapet. The first who mounted exclaimed in triumph, "The day is ours!" He was instantly shot down, and so were several others who mounted about the same time. The Americans, however, had fired their last round, their ammunition was exhausted; and now succeeded a desperate and deadly struggle, hand to hand, with bayonets, stones, and the stocks of their muskets. At length, as the British continued to pour in, Prescott gave the order to retreat. His men had to cut their way through two divisions of the enemy who were getting in rear of the redoubt, and they received a destructive volley from those who had formed on the captured works. By that volley fell the patriot Warren, who had distinguished himself throughout the action. He was among the last to leave the redoubt, and had scarce done so when he was shot through the head with a musket-ball, and fell dead on the spot.
