Meanwhile, Hessian Commander Johann Rall was held up at the home of Abraham Hunt, of Trenton, who had placated Rall and some of his officers with plenty of food and drink into the late hours of the evening and morning. At sunrise, Washington, aided by Major General Knox and artillery, led his men in a surprise attack on an unsuspecting Rall. The Hessians had 22 killed, including Colonel Rall, 83 wounded, and 850 captured with supplies.[156]
Washington retreated across the Delaware River to Pennsylvania and returned to New Jersey on January 3, 1777, launching an attack on British regulars at Princeton, with 40 Americans killed or wounded and 273 British killed or captured.[157] American Generals Hugh Mercer and John Cadwalader were being driven back by the British when Mercer was mortally wounded, then Washington arrived and led the men in a counterattack which advanced to within 30 yards (27 m) of the British line.[158]
Some British troops retreated after a brief stand, while others took refuge in Nassau Hall, which became the target of Colonel Alexander Hamilton's cannons. Washington's troops charged, the British surrendered in less than an hour, and 194 soldiers laid down their arms.
