Howe's army departed from Sandy Hook, New Jersey, across New York Bay from the occupied town of New York City on the southern tip of Manhattan Island, on July 23, 1777, and landed near present-day Elkton, Maryland, at the point of the "Head of Elk" by the Elk River at the northern end of the Chesapeake Bay, at the southern mouth of the Susquehanna River. Marching north, the British Army brushed aside American light forces in a few skirmishes. General Washington offered battle with his army posted behind Brandywine Creek, off the Christina River. While part of his army demonstrated in front of Chadds Ford, Howe took the bulk of his troops on a long march that crossed the Brandywine far beyond Washington's right flank. Due to poor scouting, the Americans did not detect Howe's column until it reached a position in rear of their right flank. Belatedly, three divisions were shifted to block the British flanking force at Birmingham Friends Meetinghouse and School, a Quaker meeting house.
