Contemplating the contingency of an early withdrawal by the
British from the occupied
American Revolutionary capital of
Philadelphia,
Washington sent
Lafayette to Barren Hill, located roughly halfway between
Valley Forge and Philadelphia in
Pennsylvania, to reconnoiter British intentions and interdict British detachments foraging for food in the surrounding countryside. On May 18, Lafayette left the Valley Forge camp with 2,400 troops and five pieces of artillery. After crossing the
Schuylkill River and turning south, he took up position at Barren Hill, which was close to Matson's Ford. A brigade and the guns were posted on the high ground, near a church, facing south. Another posting was at the Ridge Road to the south, and the Pennsylvania militia was sent to guard the road that led west from White Marsh. The British quickly discovered that the American force was nearby and decided to attack. On May 19, 1778, around 10:30 p.m.,
Maj. Gen. James Grant and a 5,000-man British force, including 15 guns, was sent toward Barren Hill. The plan was to take a circuitous route leading to the junction of White Marsh Road and Ridge Road. This would cut off any avenue of retreat for the Americans. A body of 2,000 grenadiers and dragoons would then move along Lafayette's left flank while another group would move into position on the American right. The plan would result in the American position being encircled from 3 positions, trapping them against the river. The British force was to wait until morning to attack and destroy or capture the entire American force. == Battle ==
