These advantages were considerably diminished by the capture of the Delaware frigate.
Lord Cornwallis, the day after entering Philadelphia, commenced three batteries for the purpose of acting against any American ships which might appear before the town. While incomplete, they were attacked by two American frigates, assisted by several galleys and gondolas.4 The largest, the Delaware, being left by the tide, grounded, and was captured. This event was the more interesting, as it not only gave the British general the command of the ferry, and free access to the Jersey shore, but also enabled him to intercept the communication between the forts below and Trenton, from which place the garrisons were to have drawn their military stores.
Sept. 30
The expected reinforcements, except the state regiment and militia from Virginia, being arrived, the American army amounted to eight thousand continental troops and three thousand militia. With this force General Washington determined to approach the enemy, and seize the first opportunity of attacking him. The army took a position on the Skippack road, about sixteen miles from Germantown. The British line of encampment crossed this village near its centre, and Lord Cornwallis, with four regiments of grenadiers, occupied Philadelphia. Colonel Stirling had been detached with two regiments to take possession of the fort at Billingsport and destroy the works, after which service he was directed to escort a convoy of provisions from Chester to Philadelphia. For the security of this convoy, another regiment was detached from Germantown.
General Washington determined to avail himself of this division of the British force, and to attempt to surprise the camp at Germantown. His plan was to attack both wings in front and rear at the same instant.
The divisions of Sullivan and Wayne, flanked by Conway’s brigade, were to march down the main road, and attack the left wing; while General Armstrong, with the Pennsylvania militia, should turn its left flank and attack in the rear. The commander-in-chief accompanied this column.
The divisions of Greene and Stephens, flanked by M’Dougal’s brigade, were to take a circuit by the Limekiln road, and attack the right wing.
The militia of Maryland and Jersey, under Generals Smallwood and Forman, were to march down the old York road, and, turning its right, to fall on its rear.
The division of Lord Sterling, and the brigades of Nash and Maxwell, formed the reserve.
Parties of cavalry were silently to scour the roads, and to keep up the communication between the heads of the several columns.
Oct. 4
The army moved from its ground about seven in the afternoon, and before sunrise the next morning, the advance of the column led by Sullivan drove in a piquet. The main body followed close in the rear, and engaging the light infantry and the fortieth regiment, forced them to give way. Though closely pursued, Lieutenant-Colonel Musgrave, with five companies, threw himself into a large stone house belonging to Mr. Chew, which stood directly in the way of Wayne’s division, and poured on the Americans an incessant and galling fire5 from the doors and windows.
After some unsuccessful and bloody attempts to carry the house by storm, and battering it with field artillery, which was too light to make any impression on its walls, a regiment was left to observe the party within it, and Wayne moved forward, passing to the left of the house.
In rather more than half an hour after Sullivan had been engaged, the left wing came also into action, and drove the light infantry posted in front of the British right from its ground. While pursuing the flying enemy, Woodford’s brigade, which was on the right of this wing, was arrested by a heavy fire from Chew’s house, directed against its right flank. The brigade was drawn off to the left by its commanding officer, and the field-pieces attached to it were ordered to play on the house, but were too light to be of service. The advance of that brigade being thus retarded, this part of the line was broken, and the two brigades composing the division of Stephens were not only separated from each other, but from the other division which was led by General Greene in person. That division, consisting of the brigades of Muhlenberg and Scott, encountered and broke a part of the British right wing, entered the village, and made a considerable number of prisoners.
Thus far the prospect was flattering. Had the American troops possessed the advantages given by experience, there is yet reason to believe that the hopes inspired by this favorable commencement would not have been disappointed. But the face of the country, and the darkness of the morning produced by a fog of uncommon density, co-operating with the defective discipline of the army, and the derangements of the corps by the incidents at Chew’s house, blasted these flattering appearances.
The grounds over which the British were pursued abounded in small and strong inclosures, which frequently broke the line of the pursuer’s army. The two divisions composing the right wing had been separated at Chew’s house, and immediately after their passing it, the right of the left wing was stopped at the same place, so as to cause a division of that wing also. The darkness of the morning rendered it difficult to distinguish objects; and it was impossible for the commander-in-chief to learn the situation of the whole, or to correct the confusion which was commencing. The same cause which obstructed the re-union of the broken parts of the American army, also prevented their discerning the real situation of the enemy, so as to improve the first impression.
The attacks on the flanks and rear which formed a part of the original plan, do not appear to have been made.
These embarrassments gave the British time to recover from the consternation into which they had been thrown. General Knyphausen, who commanded their left, detached two brigades to meet the right of Sullivan, which had penetrated far into the village, before his left, which had been detained at Chew’s house, could rejoin him; and the action became warm in that quarter. The British right also recovered from its surprise, and advanced on that part of Greene’s division which had entered the town. After a sharp engagement these two brigades began to retreat, and those who were most in advance were surrounded and compelled to surrender. About the same time the right wing also began to retreat. It is understood that their ammunition was expended.
Every effort to stop this retrograde movement proved ineffectual. The division of Wayne fell back on that of Stephens, and was for some time mistaken for the enemy. General confusion prevailed, and the confidence felt in the beginning of the action was lost. With infinite chagrin General Washington found himself compelled to relinquish all hope of victory, and to turn his attention to the safety of his army. The enemy not being sufficiently recovered to endanger his rear, the retreat was made without loss under cover of the division of Stephens.
In this battle about two hundred Americans were killed, near three times that number wounded, and about four hundred made prisoners. Among the killed was General Nash, of North Carolina; and among the prisoners was Colonel Matthews of Virginia, whose regiment had penetrated into the centre of the town. The loss of the British, as stated in the official return, did not exceed five hundred, of whom less than one hundred were killed. Among the latter, were General Agnew and Colonel Bird.
The American army retreated about twenty miles to Perkiomen creek, where a small reinforcement, consisting of about fifteen hundred militia, and a state regiment, was received from Virginia; after which it again advanced towards Philadelphia, and reoccupied the ground from which it had marched to fight the battle of Germantown.
The attention of both armies was now principally directed to the forts below Philadelphia.
A garrison of continental troops was placed in the fort at Red Bank, called fort Mercer, which commanded the channel between the Jersey shore and Mud island, and afforded protection to the American flotilla. The militia of Jersey were relied upon to reinforce this garrison; and also to form a corps of observation
