George Washington's crossing of the Delaware River, which occurred on the night of December 25–26, 1776, during the American Revolutionary War, was the first move in a surprise attack organized by George Washington against Hessian forces (German auxiliaries in the service of the British) in Trenton, New Jersey, on the morning of December 26. Planned in partial secrecy, Washington led a column of Continental Army troops across the icy Delaware River in a logistically challenging and dangerous operation.
