On December 25th, 1776, George Washington led a crossing of the Delaware River with an American force to continue to push back the British in New Jersey.
As they set up camp for the night, they knew that the British soldiers were pinning down their camp, so at night, they packed their stuff and snuck out of the camp
As the Continentals headed north at dawn, they met the unexpecting British rear guard, which they outnumbered 5 to 1. Firing muskets and using melee weapons such as swords, 40 Patriots, and 275 British soldiers died.
George Washington then ordered his men to retreat back to their camp in order to prevent being flanked by further British Reinforcements from General William.
The Americans primarily won solely because they outnumbered the Rear Guard of the British Five to one
The end resulted in the Americans wining the battle, with a result of 40 American deaths, 86 British deaths and 200 British Soldiers being captured.
