Final answer:
On December 26, 1776, the Battle of Trenton took place where General George Washington led a surprise attack crossing the Delaware River, capturing over 1,000 Hessians with minimal American losses.
Step-by-step explanation:
The event that took place on December 26, 1776, where General George Washington crossed the Delaware River, was the Battle of Trenton. This pivotal encounter saw Washington lead the Continental Army into a surprise attack against Hessian forces stationed in Trenton, New Jersey. The attack took place shortly after nightfall on December 25, 1776, and continued into the early hours of December 26th. The revolutionary army executed a tactical surprise, resulting in the capture of over 1,000 Hessian soldiers, while the American losses were fewer than ten dead or wounded. Washington's bold strategy and victory at Trenton significantly boosted the morale of the American cause and helped turn the tide of events following several British successes earlier in the year.
