There is a belief that General Cornwallis's sword, surrendered by Charles O'Hara after the battle, is to this day on display at the White House. However, U.S. National Park Service historian Jerome Green, in his 2005 history of the siege, The Guns of Independence, concurs with the 1881 centennial account by Johnston, noting simply that when Brigadier General O'Hara presented the sword to Major General Lincoln, "he held it for a moment and immediately returned it to O'Hara."[88]
