might harass the rear of any detachment investing6 the place.
Oct. 1777
General Howe was indefatigable in his preparations to attack fort Mifflin from the Pennsylvania shore. He erected batteries at the mouth of the Schuylkill, which were silenced by Commodore Hazlewood; but a detachment crossed over Webb’s ferry into Province Island in the following night, and constructed a slight work opposite fort Mifflin, from which they were able to throw shot and shells into the barracks. This was attacked at daylight by three galleys and a floating battery, and the garrison surrendered. While the boats were bringing off the prisoners, a large body of British troops reoccupied the fortress. The attack was renewed by the flotilla, without success; and two attempts made by Lieutenant-Colonel Smith to storm it, entirely failed. In a few nights, works were completed on the high ground of Province Island, which enfiladed7 the principal battery of fort Mifflin.
The aids expected from the Jersey militia not being received, Colonel Angel of Rhode Island, with his regiment, was ordered to Red Bank; and Lieutenant-Colonel John Goune of Virginia, with about two hundred men, to fort Mifflin.
Immediately after the battle of Brandywine, Admiral Howe8 sailed for the Delaware; but his van did not get into the river until the 4th of October. The ships of war and transports which followed, came up from the 6th to the 8th, and anchored from New Castle to Reedy Island. It was not till the middle of the month, that the frigates in advance of the fleet could make a narrow and intricate passage through the lower impediments sunk in the river. In the meantime the fire from the Pennsylvania shore had not produced all the effect expected from it; and General Howe perceived that greater exertions would be necessary for the reduction of the works than could be safely made in the present relative situation of the armies. Under this impression, he withdrew his troops from Germantown into Philadelphia, as preparatory to a combined attack by land and water on forts Mercer and Mifflin.
After effecting a passage through the works sunk in the river at Billingsport, other difficulties still remained to be encountered by the ships of war. Several rows of chevaux-de-frise had been sunk about half a mile below Mud island, which were protected by the guns of the forts, as well as by the moveable water force. To silence these works, therefore, was a necessary preliminary to the removal of the obstructions in the channel.
On the 21st of October, Colonel Count Donop, at the head of twelve hundred Hessians, crossed the Delaware at Philadelphia, with orders to storm the works at Red Bank. Late in the evening of the 22d, he appeared before the fort, and attacked it with great intrepidity. It was defended with equal resolution. The outer works, being too extensive to be manned by the garrison, were used only to gall the assailants while advancing. On their near approach, the Americans retired within the inner entrenchment, whence they poured upon the Hessians a heavy and destructive fire. Colonel Donop received a mortal wound; and Lieutenant-Colonel Mengerode, the second in command, fell about the same time. Lieutenant-Colonel Minsing, the oldest remaining officer, drew off his troops, and returned next day to Philadelphia. The loss of the assailants was estimated at four hundred men. That of the Americans amounted to only thirty-two in killed and wounded.
The ships having been ordered to co-operate with Count Donop, the Augusta and four smaller vessels passed the lower line of chevaux-de-frise opposite Billingsport, and lay above it, waiting for the assault. The flood tide setting in as the attack commenced, they moved with it up the river. The obstructions sunk in the Delaware, having in some degree changed its channel, the Augusta and the Merlin grounded a considerable distance below the second line of chevaux-de-frise; and a strong wind from the north so checked the rising of the tide, that they could not be floated by the flood. The next morning, their situation was discovered, and four fire-ships were sent to destroy them, but without effect. Meanwhile, a warm cannonade was kept up on both sides, in the course of which the Augusta took fire, and it was found impracticable to extinguish the flames. Most of the men were taken out, the frigates withdrawn, and the Merlin set on fire; after which the Augusta blew up, and a few of the crew were lost in her.
Congress expressed its high sense of the merits of Colonel Greene, of Rhode Island, and of Lieutenant-Colonel Smith, of Maryland, who had commanded in the forts; and of Commodore Hazlewood, who had commanded the galleys, and presented a sword to each of those officers.
This repulse inspired sanguine hopes that the posts on the Delaware might be defended so long as to induce the evacuation of Philadelphia. But their condition did not justify this confidence.
Having failed in every attempt to draw the militia of Jersey to the Delaware, General Washington determined to strengthen the garrisons by further drafts from his army. Three hundred Pennsylvania militia were detached to be divided between them, and General Varnum’s brigade was ordered to take a position near Red Bank, and to relieve and reinforce the garrisons of both forts. The hope was entertained, that the appearance of a respectable continental force might encourage the militia to assemble in greater numbers.
In this state of things, intelligence was received of the successful termination of the northern campaign;9 in consequence of which, great part of the troops who had been employed against Burgoyne might be drawn to the aid of the army in Pennsylvania. Colonel Hamilton10 was dispatched to General Gates, to make the proper representations to that officer, and to urge him, if he contemplated no other service of more importance, to send immediately the regiments of Massachusetts and New Hampshire to aid the army of the middle department.
On reaching General Putnam, Colonel Hamilton found that a considerable part of the northern army had joined that officer; but that Gates had detained four brigades at Albany, for an expedition intended to be carried on in the winter against Ticonderoga.
Having made arrangements with Putnam for the immediate march of a large body of continental troops, Colonel Hamilton proceeded to Albany, for the purpose of remonstrating with General Gates against retaining so large and valuable a part of the army unemployed at a time when the most imminent danger threatened the vitals of the country. Gates was by no means disposed to part with his troops. He would not be persuaded that an expedition then preparing at New York was designed to reinforce General Howe; and insisted, that by a sudden movement up the Hudson, it would be in the power of the enemy, should Albany be left defenceless, to destroy the valuable arsenal at that place, and the military stores captured with Burgoyne.
After obtaining, by repeated remonstrances, an order directing three brigades to the Delaware, Hamilton hastened back to Putnam, and found the troops which had been ordered to join General Washington, still at Peekskill. The detachment from New York had suggested to Putnam the possibility of taking that place; and he does not appear to have made any great exertions to divest himself of a force which might enable him to accomplish an object that would give so much splendor to his military character. In addition to this circumstance, an opinion had insinuated itself among the soldiers that their share of service for the campaign had been performed, and that it was time for them to go into winter quarters. Great discontent, too, prevailed concerning their pay, which the government had permitted to be more than six months in arrear; and, in Poor’s brigade, a mutiny broke out, in the course of which a soldier, who was run through the body by his captain, shot the officer dead before he expired. Colonel Hamilton came in time to borrow money of the Governor of New York, to put the troops in motion; and they proceeded by brigades to the Delaware. But delays retarded their arrival until the contest for the forts on that river was terminated.
The preparations of Sir William Howe being completed, a large battery on Province Island, of twenty-four and thirty-two pounders, and two howitzers of eight inches each,11 opened early in the morning of the 10th of November, upon fort Mifflin, at the distance of five hundred yards, and kept up an incessant fire for several days. The block-houses were reduced to a heap of ruins; the palisades were beaten down;12 most of the guns disabled, and the barracks battered in every part so that the troops could not remain in them. They were under the necessity of working and watching through the night; and, if in the day a few moments were allowed for repose, it was taken on the wet earth, which incessant rains had rendered a soft mud. The garrison was relieved by General Varnum every forty-eight hours; but his brigade was so weak that half the men were constantly on duty.
