On the right, Hitchcock's New Englanders fired a volley and then advanced again, threatening to turn the British flank.Ketchum, 1999, pp. 361–364 The riflemen were slowly picking off British soldiers while the American artillery was firing grapeshot at the British lines. At this point, Hitchcock ordered his men to charge, and the British began to flee. The British attempted to save their artillery, but the militia also charged, and Mawhood gave the order to retreat. The British fled towards the Post Road followed by the Americans. Washington reportedly shouted, "It's a fine fox chase my boys!" Some Americans had swarmed onto the Post Road in order to block a British retreat across the bridge, but Mawhood ordered a bayonet charge and broke through the American lines, escaping across the bridge. Some of the Americans, Hand's riflemen among them, continued to pursue the British, and Mawhood ordered his dragoons to buy them some time to retreat; however, the dragoons were pushed back. Some Americans continued to pursue the fleeing British until nightfall, killing some and taking some prisoners.Ketchum, 1999, p. 300 After some time, Washington turned around and rode back to Princeton.Ketchum, 1999, pp. 361–364
