Which Hessian commander was killed at the Battle of Trenton?

Johann Rall was the Hessian commander killed at the Battle of Trenton.

Rall, also spelled Rahl, was a German colonel from Hesse-Kassel who commanded roughly 1,200 Hessian troops stationed in and around Trenton, New Jersey. On the night of December 25–26, 1776, George Washington’s army crossed the Delaware River and launched a surprise attack on the garrison.

Rall’s troops initially tried to organize a counterattack, but American forces surrounded the town and brought fire from several directions. Rall was mortally wounded while leading his men, reportedly suffering two gunshot wounds to the side. He was carried to his headquarters in Trenton, where he died later on December 27, 1776.

His defeat became one of the Revolution’s most important morale-boosting American victories. The Hessians surrendered, with about 900 captured, while Rall’s death deprived them of their principal battlefield commander. Carl von Donop was Rall’s superior, but he was not killed at Trenton; he was away commanding operations near Mount Holly.
