Gouverneur Kemble Warren was an American civil engineer and Union Army general during the American Civil War. He is best remembered for arranging the last-minute defense of Little Round Top during the Battle of Gettysburg and is often referred to as the "Hero of Little Round Top." His subsequent service as a corps commander and his remaining military career were ruined during the Battle of Five Forks, when he was relieved of command of the V Corps by Philip Sheridan, who claimed that Warren had moved too slowly.
