It opened with terrible effect on the morning of the 14th, yet that little garrison of only three hundred men managed to silence it before noon. Hitherto the enemy did not know the real weakness of the garrison; on that day a deserter, in a boat, carried information of the fact to the British, who were seriously thinking of abandoning the siege, for they had suffered much. Hope was revived, and preparations were made for a general and more vigorous assault. At daylight, on the 15th, the Iris and Somerset, men-of-war, passed up the east channel to attack the fort on Mud Island in front. Several frigates were brought to bear on Fort Mercer; and the Vigilant, an East Indiaman of twenty twenty-four pounders, and a hulk with three twenty-four pounders, made their way through a narrow channel on the western side, and gained a position to act in concert with the batteries on Province Island, in enfilading the American works. At ten o'clock, while all was silent, a signal-bugle sent forth its summons to action, and instantly the land batteries and the shipping poured a terrible storm of missiles upon Fort Mifflin. The little garrison sustained the shock with astonishing intrepidity, and far into the gloom of evening an incessant cannonade was kept up. Within an hour, the only two cannons in the fort which had not been dismounted shared the fate of the others. Every man who appeared upon the platform was killed by the musketeers in the tops of the ships, whose yards almost hung over the American battery. Long before night not a palisade was left; the embrasures were ruined; the whole parapet leveled; the block-houses were already destroyed. Early in the evening Major Thayer sent all the remnant of the garrison to Red Bank, excepting forty men, with whom he remained. Among those sent was the brave Captain

The small island between Red Bank Island and the Jersey shore is Woodbury Island, on which the Americans erected a small battery. The creek, just below Fort Mercer, is Woodbury Creek, a deep and sluggish stream, near the Delaware.
Retreat of the Garrison.—Destruction of the Fort.—Movements in New Jersey.—Fort Mercer Abandoned.
(afterward Commodore) Talbot, of the Rhode Island line, who was wounded in the hip, having fought for hours with his wrist shattered by a musket ball. At midnight, every defense and every shelter being swept away, Thayer and his men set fire to the remains of the barracks, evacuated the fort, and escaped in safety to Red Bank. Altogether it was one of the most gallant and obstinate defenses made during the war. In the course of the last day, more than a thousand discharges of cannon, from twelve to thirty-two pounders, were made against the works on Mud Island. Nearly two hundred and fifty men of the garrison were killed and wounded. The loss of the British was great; the number was not certainly known. *
Fort Mercer was still in possession of the Continental troops. Howe determined to dislodge them; for, while they remained, the obstructions in the river could not, with safety, be removed. While a portion of his force was beating down Fort Mifflin, he was busy in fortifying Philadelphia. He had extended intrenchments across from the Delaware to the Schuylkill. Having received more re-enforcements from New York, he sent Cornwallis to fall upon Fort Mercer in the rear. That officer, with a detachment of about two thousand men, crossed the Delaware from Chester to Billingsport, where he was joined by some November 18, 1777 troops just arrived from New York. Washington had been apprised of this movement, and had detached General Huntington's brigade to join that of Varnum in New Jersey. He also ordered Major-general Greene to proceed with his division to the relief of the garrison, and to oppose Cornwallis. That able officer, accompanied by La Fayette, who had not yet quite recovered from a wound received in the battle on the Brandywine, crossed the Delaware at Burlington, and marched with a considerable force toward Red Bank. He expected to be re-enforced by Glover's brigade, then on its march through New Jersey, but was disappointed. Ascertaining that the force of Cornwallis was greatly superior to his own in numbers, General Greene abandoned the plan of giving him battle, and filed off toward Haddonfield. Colonel Greene, deprived of all hope of succor, evacuated Fort Mercer, leaving the artillery, with a considerable quantity of cannon-balls and stores, in the hands November 20 of the enemy. Cornwallis dismantled the fort and demolished the works. His army was augmented by re-enforcements, and, with about five thousand men, he took post at and fortified Gloucester Point, whence he might have a supervision of affairs in Lower Jersey. Morgan's rifle corps joined General Greene, but the Americans were not strong enough to venture a regular attack upon Cornwallis. A detachment of one hundred and fifty riflemen, under Lieutenant-colonel Butler, and an equal number of militia, under La Fayette, attacked a picket of the enemy three hundred strong, killed between twenty and thirty of them, drove the remainder quite into the camp at Gloucester, and returned without losing a man. General Greene soon afterward withdrew from New Jersey and joined Washington, and Cornwallis returned to Philadelphia. The American fleet, no longer supported by the forts, sought other places of safety. On a dark night, the galleys, one November 21, 1777 brig, and two sloops, crept cautiously along the Jersey shore past Philadelphia, and escaped to Burlington. Seventeen other vessels, unable to escape, were abandoned by their crews, and burned at Gloucester. ** The American defenses on the Delaware were now scattered to the winds; the obstructions in the river were removed; the enemy had full possession of Philadelphia; Congress had fled to the interior, and the broken battalions of the patriot army sought winter quarters on the banks of the Schuylkill, at Valley Forge.
Gloomy indeed were the November twilights of 1777 to the eye and heart of the patriot, for there were no brilliant omens of a pleasant to-morrow. Not so was the bright sunset and radiant twilight of that November evening in 1848, when we left the ruins at Red Bank and sought a waterman to convey us back to League Island. There was no cloud in the heavens; an orange glow suffused the chambers of the west where the king of day had gone to his couch, and promises of a fair to-morrow were revealed in the clear sky.
