The document describes the Battle of Trenton during the American Revolutionary War. It explains that while the British were celebrating their victories on Christmas, General Washington led around 2,000 men in a surprise overnight attack against the British forces in Trenton. Though they faced difficulties crossing the Delaware River, the Patriots were able to take the British by surprise when most of their officers were drunk. This victory boosted American morale and was a turning point in the war, after many previous losses.
