The British attack was organized with Hessian regiments leading the assault. Rall was to charge the American right, while a Hessian battalion under Colonel Carl von Donop (consisting of the Linsing, Mingerode, Lengereck, and Kochler grenadiers, and Donop's own chasseur regiment) was to attack the center. A British column under General Alexander Leslie (consisting of the 5th, 28th, 35th, and 49th Foot) was to attack the right. Donop's force either had difficulty crossing the river, or was reluctant to do so, and elements of the British force were the first to cross the river. Rall's charge scattered the militia on the American right, leaving the flank of the Maryland and New York regiments exposed as they poured musket fire onto the British attackers, which temporarily halted the British advance. The exposure of their flank caused them to begin a fighting retreat, which progressively forced the remainder of the American line, which had engaged with the other segments of the British force, to give way and retreat. Haslet's Delaware regiment, which anchored the American left, provided covering fire while the remaining troops retreated to the north, and were the last to leave the hill. The fighting was intense, and both sides suffered significant casualties before the Continentals made a disciplined retreat.
