During the winter Howe formed a plan for taking Philadelphia, and on December 20, 1776, expounded it by letter to Germain, observing that the northern army would not reach Albany before September. Germain wrote on March 8 approving of his plan,[122] which might have been executed without preventing the junction contemplated by the minister. After some unimportant operations Howe took the field in June, and on the 5th received a copy of Carleton's instructions relating to Burgoyne's campaign. Washington's difficulties were then somewhat relieved; he encamped at Middlebrook in a position too strong to be forced; he would not be enticed to a general engagement, and Howe could not leave him in his rear and push on to Philadelphia. Time was passing, yet Howe was still set on prosecuting his design on Philadelphia. Finally he embarked an army of 14,000 men at Sandy Hook, and instead of remaining to be in readiness to co-operate with Burgoyne, left Clinton with 8,500 men to garrison New York and "act as circumstances may direct," and on July 23 sailed for the Delaware, where he considered he would be sufficiently near to New York to act with Burgoyne, if necessary, and yet could carry out his own main design. The naval officers were unwilling to risk disembarkation in the Delaware, and Howe, determined not to give up his design, sailed for Chesapeake bay. The fleet met with contrary winds, and it was not until August 25 that his army landed at the head of Elk river. Washington with about an equal force marched to the north of the Brandywine to defend Philadelphia. The two armies met on September 11. Howe, who well knew how to handle an army in the field, out-manoeuvred him, and after some sharp fighting the American army was defeated with a loss of over 1,400 men, killed, wounded, and taken, and eleven guns. Congress again decamped, and on the 27th Cornwallis took possession of Philadelphia amid the acclamations of a large part of the inhabitants, while Howe and the main army encamped at Germantown, five miles to the north.
