M'Dougal continued his march towards the Delaware; and the utmost exertions were made both by Governor Livingston and General Dickinson to collect the militia for the purpose of aiding the army in Pennsylvania. The success of their exertions did not equal their wishes. The militia being of opinion that there was danger of a second invasion from New York, and that their services were more necessary at home than in Pennsylvania, assembled slowly and reluctantly. Five or six hundred crossed the Delaware at Philadelphia, about the time Sir William Howe crossed the Schuylkill, and were employed in the removal of stores. On the approach of the British army, they were directed to avoid it by moving up the Frankford road; but the commanding officer, having separated himself from his corps, was taken by a party of British horse employed in scouring the country; on which the regiment dispersed, and returned by different roads to Jersey. With much labour General Dickinson assembled two other corps amounting to about nine hundred men, with whom he was about to cross the Delaware when intelligence was received of the arrival at New York of a reinforcement from Europe. He was detained in Jersey for the defence of the state, and the militia designed to serve in Pennsylvania were placed under General Forman. About six hundred of them reached the army a few days before the battle of Germantown, immediately after which they were permitted to return.] The attention of both armies was most principally directed to the forts below Philadelphia. The loss of the Delaware frigate, and of Billingsport, greatly discouraged the seamen by whom the galleys and floating batteries were manned. Believing the fate of America to be decided, an opinion strengthened by the intelligence received from their connexions in Philadelphia, they manifested the most alarming defection, and several officers as well as sailors deserted to the enemy. This desponding temper was checked by the battle of Germantown, and by throwing a garrison of continental troops into the fort at Red Bank, called fort Mercer, the defence of which had been entrusted to militia. This fort commanded the channel between the Jersey shore and Mud Island; and the American vessels were secure under its guns. The militia of Jersey were relied on to reinforce its garrison, and also to form a corps of observation which might harass the rear of any detachment investing the place.
