From the Deleware official website is this:
King George almost abdicated the throne when the British lost!
After Yorktown, George III vowed to keep fighting. When parliament demurred, the King wrote a letter of abdication -- then withdrew it. He tried to console himself with the thought that Washington would become a dictator and make the Americans long for royal rule. When he was told that Washington planned to resign his commission, the monarch gasped: "If he does that, sir, he will be the greatest man in the world."
