At 11 p.m. on Christmas Day, 1776, George Washington and some of his troops boarded boats and crossed the ice-choked Delaware River to launch an attack on roughly 1,400 Hessian soldiers quartered at Trenton, New Jersey. Rain, sleet, and snow lashed the Americans, and a nor’easter buffeted them with fierce winds. Three hours behind schedule, and lacking the full complement of his troops, Washington marched his men 10 miles to Trenton, attacked the sleeping Hessians, and won an overwhelming victory, one of minor strategic importance but which delivered a huge boost to American morale.
Few of us would choose to spend Christmas beset by such suffering and foul weather, yet Washington’s choice of the day itself provided a tactical advantage to the Americans. The Hessians were mostly Lutherans and Catholics, accustomed to celebrating Christmas with food and drink. The Americans were mostly Protestants who abjured those celebrations. To them, Christmas was just a day like any other, and they caught their enemy off-guard and sleeping.
