Honor and Humility: The Secret of Cornwallis's Surrender
« I fell upon an army that had surrendered. »— General Benjamin Lincoln, after the surrender of Yorktown
The surrender at Yorktown on October 19, 1781, is an emblematic moment of the American War of Independence. However, the surrender protocol was marked by a curious absence: British General Lord Cornwallis, feigning illness, did not personally present himself to offer his sword. He delegated his second-in-command, Brigadier General Charles O'Hara, to perform this humiliating task, causing unease among officers of both sides.
In response, George Washington, refusing to accept a subordinate's sword, instructed his own second-in-command, Major General Benjamin Lincoln, to accept the surrender. This exchange, imbued with symbolism and wounded dignity, marked the end of major hostilities. The victory at Yorktown, while a demonstration of military force, was also a lesson in the codes of honor and the pride of generals facing defeat.
