The Passage of the Delaware is a large, Neoclassical 1819 oil-on-canvas painting by Thomas Sully. With attention to historical accuracy, the painting depicts George Washington on horseback observing the troops of the American Revolutionary Army in the process of crossing the Delaware River prior to the surprise attacks on Hessian troops on December 26, 1776 at the Battle of Trenton. The image is intended to capture the moment prior to George Washington dismounting his horse and joining his army in crossing the Delaware River.
