heres what i found: The battle lasted just one hour before the Hessians surrendered to General Sullivan. Overall, Hessian forces suffered 22 deaths, 83 injuries, and 896 were captured.
Also: Before the battle, Washington commissioned a spy named John Honeyman posing as a Tory (or British sympathizer) to Trenton. Honeyman has plenty of experience dealing with the British and the Hessians. After staying there for several days, he allowed himself to be captured by Washington’s army and provided exceptional intelligence about the Hessian forces in Trenton.
