Gen. Howe responded to the fall of Trenton by sending 5,550 troops south from New York through Princeton toward Trenton. Gen. Cornwalis' troops arrived in Trenton late on the afternoon of the 2nd of January. Cornwalis found Gen. Washington's troops along the ridge of the Assunpink Creek, and decided to wait until the next day to attack. Overnight, Washington moved his troops out of Trenton and into Princeton to the north. There, his advance force met a British blocking force commanded by Lieutenant Colonel Charles Mawhood. A desperate fight ensued in Princeton, in which the Americans almost lost. Washington's timely arrival on horseback, however, served to rally the Americans, and the Colonial army defeated Mawhood's troops, forcing them to retreat to Trenton. Both armies were spent, and Washington took his army into winter quarters in Morristown, while Cornwalis withdrew to New Brunswick.
