The Battle of Trenton was a small but pivotal American Revolutionary War battle on the morning of December 26, 1776, in Trenton, New Jersey. After General George Washington's crossing of the Delaware River north of Trenton the previous night, Washington led the main body of the Continental Army against Hessian auxiliaries garrisoned at Trenton. After a brief battle, almost two-thirds of the Hessian force were captured, with negligible losses to the Americans. The battle significantly boosted the Continental Army's waning morale, and inspired re-enlistments.
The Continental Army had previously suffered several defeats in New York and had been forced to retreat through New Jersey to Pennsylvania. Morale in the army was low; to end the year on a positive note, George Washington, Commander-in-Chief of the Continental Army, devised a plan to cross the Delaware River on the night of December 25–26 and surround the Hessians' garrison.
