General Howe granted Cornwallis leave in December 1776; however it was cancelled after Washington launched his surprise attack on Trenton on 26 December. Howe ordered Cornwallis to return to New Jersey to deal with Washington. Cornwallis gathered together garrisons scattered across New Jersey and moved them towards Trenton. On 2 January 1777, as he advanced on Trenton, his forces were engaged in extended skirmishing that delayed the army's arrival at Washington's position on the Assunpink Creek until late in the day. Cornwallis was unable to dislodge Washington in the battle that followed.
