Gen. Daniel E. Sickles and Gen. Samuel P. Heintzelman 524677
US Gen Sickles was immediately brought to Washington DC after his leg was blown off by a cannon at Gettysburg. Lincoln & son Tad visited Sickles at his boarding house the afternoon of his arrival from the field. Sickles used the opportunity to spin his version of why he disobeyed orders at Gettysburg. Instead of a court martial, he was awarded the Medal of Honor.
At the time, Gen Heintzelman commanded the Defense of Washington & was photographed during a visit.
Oddly enough, Sickles would visit his leg on the anniversary of the amputation. Aware of the request from the Army Surgeon General to collect "specimens of morbid anatomy", Sickles donated his amputated leg in a small coffin-shaped box, along with a visiting card marked, "With the compliments of Major General D.E.S." The leg is currently on display at the National Museum of Health and Medicine, with a cannonball similar to the one that shattered it.
