Instead, only one column succeeded in crossing the Delaware, and hours behind schedule. Yet in this confluence of challenge, error, and bad breaks, Washington exhibited an enduring priority of the American military: adaptability. He pressed the attack, and his victory saved the Patriot cause.
Washington’s crossing of the Delaware River was a desperate act. As 1776 drew to a close, the commander-in-chief feared that the defeat of the American rebellion was at hand. British General William Howe had captured New York City in mid-November, ending months of fighting for control of the American capital city. Running low on supplies and morale, Washington removed the Continental Army to Pennsylvania to rest and reset.
Throughout December, the situation of Washington’s army became desperate. Many of his soldiers were sick and wounded—a little less than 4,000 were fit for duty, which was almost 1,000 under strength. Expiring enlistments worsened the situation, and the new year would bring the end of service for yet more men.
But back in New York City, General Howe felt confident of an impending British victory over the rebellion. He pivoted to focus on undermining the Patriot cause through imperial power. He established outposts of troops in the mid-Atlantic interior, including a 1,500 Hessian garrison in the quiet town of Trenton, New Jersey.
Another commander might have resorted to winter quarters and wound licking. But instead of wallowing in these circumstances, Washington was tenacious—and adaptable.
Together with his officers and aide-de-camp Colonel Joseph Reed, Washington began meticulously planning a tactical surprise against Trenton. Three columns of troops marching in close order would cross the Delaware River and march to the garrison. Washington would personally command the column that would mount the pre-dawn northerly attack. Two more columns of Pennsylvania militia and Continental Army soldiers would cross further south. One would wage a diversionary attack against the British garrison at Bordentown, New Jersey, while the other prevented the enemy’s retreat in that direction.
These difficult conditions delayed the column even further, rendering a pre-dawn attack impossible. Pressing on toward Trenton, Washington received word that one of his officers, General Adam Stephen, unaware of the planned attack, had attacked the garrison earlier that morning in a bid to avenge a recent engagement. Thinking the element of surprise now moot, Washington nonetheless pressed his men onwards.
Lt. Gen. Milford H. Beagle, Jr., the commanding general of the U.S. Army Combined Arms Center, said at the conference that “we train for certainty, we educate for uncertainty, and then we develop for the unknown.” Washington understood the importance of contingency readiness, even as his competent military leadership, manifested in his placing militiamen along the Delaware to harass the British, improved his chances of victory at Trenton.
Washington’s columns pressed the Hessians first into retreat, then to surrender. The American victory gave the Continental Army the morale and popular support it needed to fight another day, leading to subsequent victories at Assunpink Creek and Princeton.
Trenton is a testament to the importance of military adaptability, which remains a critical component of American military doctrine today.
