Maj. General Benjamin Lincoln was paroled following his surrender of Charleston on May 12, 1780, but he did not reach Philadelphia until July 1780. He requested a court of inquiry, but none was appointed and no charges were ever brought against him. He returned to his farm at Hingham and waited to be exchanged. Finally in November, 1780, he was exchanged for Maj. General William Philips and Baron Friedrich von Riedesel, both of whom had been captured at Saratoga. He spent the winter recruiting and gathering supplies in Massachusetts.
In the summer of 1781, Lincoln commanded troops around New York City. In August 1781, General George Washington picked Lincoln to lead the American army in its march south to Yorktown. Various myths have grown out of the Yorktown surrender ceremony on October 20, 1781. Lt. General Charles Cornwallis claimed illness and sent his second-in-command Brig. General Charles O'Hara in his stead. O'Hara is said to have attempted to first surrender his sword to French General Comte de Rochambeau. Rochambeau declined his sword, deferring to Washington. Washington is then said to have instructed O'Hara to surrender the sword to his second-in-command, Lincoln.
