This hand-colored map depicts the surprise attack by Continental troops on a garrison of Hessians in Trenton, New Jersey, on the morning of December 26, 1777. The Hessians were German mercenaries fighting for the British during the war. A key on the right side of the map indicates the positions taken by the troops under the command of General George Washington as well as the positions held by the Hessians. Lieutenant Andreas Wiederholdt, a Hessian officer involved in the engagement, created this map that he subsequently submitted to a court of inquiry in Philadelphia concerning the battle. The Battle of Trenton was a significant victory for the Continental forces.
