Philadelphia, which forms one continued street nearly two miles in
length. The British line of encampment crossed this village at right
angles near the centre, and Lord Cornwallis, with four regiments of
grenadiers, occupied Philadelphia. The immediate object of General
Howe being the removal of the obstructions in the river, Colonel
Stirling, with two regiments, had been detached to take possession of
the fort at Billingsport, which he accomplished without opposition.
This service being effected, and the works facing the water destroyed,
Colonel Stirling was directed to escort a convoy of provisions from
Chester to Philadelphia. Some apprehensions being entertained for the
safety of this convoy, another regiment was detached from Germantown,
with directions to join Colonel Stirling.[67]

This division of the British force appeared to Washington to furnish a
fair opportunity to engage Sir William Howe with advantage.
Determining to avail himself of it, he formed a plan for surprising
the camp at Germantown, and attacking 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, entering the town by the way of
Chesnut Hill, to attack the left wing; while General Armstrong, with
the Pennsylvania militia, was to move down the Manatawny road[68] by
Vanduring's mill, and turning the left flank to attack in the rear.
The Commander-in-chief accompanied this column.
