Daniel Sickles (1819-1914) was a New York politician and controversial Union general during the American Civil War (1861-65). Prior to the war, Sickles had been tried, and acquitted, of killing his wife’s lover, becoming the first person to successfully use temporary insanity as legal defense. A political apointee, and not a military general, Sickles’ combat career ended after his disatrous performance at the Battle of Gettysburg, during which he disobeyed the orders of his commanding officer, Union Maj. George Meade. Sickles insubordination rled to the near destruction of his corps and a severe wound that required the amputation of his right leg. After the war, Sickles served as a U.S. diplomat, congressman and federal official overseeing Reconstruction.
