Battle of Princeton

The Battle of Princeton occured on January 3, 1777 and was in Princeton, New Jersey. Upon sighting the American force, Mawhood formed up his men in a defensive position across the edge of an orchard, which Mercer's troops were passing through. A violent firefight ensued, and Mawhood launched an assault which largely cleared the orchard of Mercer's troops, who began to retreat in confusion. General Mercer was wounded but refused to surrender. When he tried to attack the enemy with his sword, he was bayoneted and presumed dead; he died of his wounds nine days later. Colonel John Haslet of Delaware replaced General Mercer and was killed by a shot to the head.

During the confusion, General Washington rode up to rally Mercer's men, while a fresh brigade of 2,100 troops under General John Cadwalader arrived with an artillery battery. Washington then rode straight into the British fire, personally leading the attack. Legend has it that Washington was obscured by smoke, but when it cleared, he was still there.

With Cadwalader's reinforcements and Washington's successful rallying of Mercer's men, the larger American force was able to attack the British flanks and retake most of the orchard, until fire from Mawhood's guns halted the American advance.

A second British assault cleared the orchard, and seemed about to win the day until Sullivan led up another 1,300 troops. Now outnumbered nearly 6 to 1, Mawhood led a final charge to break through the American lines. A number of British soldiers broke through the Americans in a desperate bayonet charge, continuing down the road to Trenton. Washington led some of his force in pursuit of Mawhood, then abandoned the pursuit and turned around when some of Leslie's 2nd Brigade troops were sighted. The remainder of the British force fell back to Princeton, where, along with the troops already present, they defended the town against Sullivan's force before retreating to New Brunswick. A number of British troops left behind in Princeton, facing overwhelming numbers and artillery fire, surrendered. The British casualty list stated 86 killed and wounded, and 200 captured. The Americans suffered 40 killed and wounded.
In Trenton, Cornwallis and his men awoke to the sounds of cannon fire coming from behind their position. Cornwallis and his army began to race towards Princeton. However, Washington's rear guard had managed to damage the bridge over the Stony Brook, and American snipers further delayed Cornwallis' advance. The exhausted American Army slipped away, marching to Somerset County Courthouse (now Millstone), where they spent the night. When the main British force finally reached Princeton late in the day, they did not stay but quickly continued on toward New Brunswick.
