The attacks on the flanks and rear, which formed a part of the original plan, do not appear ever to have been made. The Pennsylvania militia came in view of the chasseurs who flanked the left of the British line, but did not engage them closely. The Maryland and Jersey militia just showed themselves on the right flank, about the time Greene was commencing a retreat.
The Americans repulsed.
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 this 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 which 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 they had expended their ammunition.
Every effort to stop this retrograde movement proved ineffectual. The division of Wayne fell back on that of Stephen, and was for an instant mistaken for the enemy. General confusion prevailed, and the confidence felt in the beginning of the action was lost. With infinite chagrin General Washington was compelled to relinquish his hopes of victory, and turn his attention to the security 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 Stephen, which had scarcely been in the engagement.
In this battle, about two hundred Americans were killed, near three times that number wounded, and about four hundred were 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 of General Howe, did not much exceed five hundred in killed and wounded, of whom less than one hundred were killed; among the latter were Brigadier General Agnew and Colonel Bird.
The American army retreated the same day, about twenty miles, to Perkyomy Creek, where a small reinforcement, consisting of fifteen hundred militia and a state regiment, was received from Virginia; after which it again advanced towards Philadelphia, and encamped once more on Skippack Creek.
The plan of the battle of Germantown must be admitted to have been judiciously formed; and, in its commencement, to have been happily conducted. But a strict adherence to it by those who were entrusted with the execution of its several parts, was indispensable to its success.
Major General Stephen, who commanded the right division of the left wing, was cashiered for misconduct on the retreat, and for intoxication.
Congress expressed, in decided terms, their approbation both of the plan of this enterprise, and of the courage with which it was executed; for which their thanks were given to the general and the army.[71]
