Several of the garrison were killed and among them Captain Treat, a gallant officer, who commanded the artillery. Colonel Smith received a contusion on his hip and arm which compelled him to give up the command and retire to Red Bank. Major Fleury, a French officer of distinguished merit, who served as engineer, reported to Washington that, although the blockhouses were beaten down, all the guns in them, except two, disabled, and several breaches made in the walls, the place was still defensible; but the garrison was so unequal to the numbers required by the extent of the lines, and was so dispirited by watching, fatigue, and constant exposure to the cold rains, which were almost incessant, that he dreaded the event of an attempt to carry the place by storm. Fresh troops were ordered to their relief from Varnum's brigade, and the command was taken, first by Colonel Russell, and afterward by Major Thayer. The artillery, commanded by Captain Lee, continued to be well served. The besiegers were several times thrown into confusion, and a floating battery, which opened on the morning of the 14th, was silenced in the course of the day. The defense being unexpectedly obstinate, the assailants brought up their ships (November 15, 1777) as far as the obstructions in the river permitted and added their fire to that of the batteries, which was the more fatal as the cover for the troops had been greatly impaired. The brave garrison, however, still maintained their ground with unshaken firmness. In the midst of this stubborn conflict, the Vigilant and a sloop-of-war were brought up the inner channel, between Mud and Province Islands, which had, unobserved by the besieged, been deepened by the current in consequence of the obstructions in the main channel, and, taking a station within 100 yards of the works, not only kept up a destructive cannonade, but threw hand-grenades into them, while the musketeers from the round-top of the Vigilant killed every man that appeared on the platform. Major Thayer applied to the Commodore to remove these vessels, and he ordered six galleys on the service, but, after reconnoitering their situation, the galleys returned without attempting anything. Their report was that these ships were so covered by the batteries on Province Island as to be unassailable. It was now apparent to all that the fort could be no longer defended. The works were in ruins. The position of the Vigilant rendered any further continuance on the island a prodigal and useless waste of human life; and on the 16th, about 11 at night, the garrison was withdrawn. A second attempt was made to drive the vessels from their stations, with a determination, should it succeed, to repossess the island, but the galleys effected nothing, and a detachment from Province Island soon occupied the ground which had been abandoned.
