PHILIP HENRY SHERIDAN was a prominent Union general, who spent his whole adult life in the Army. Some of his Civil War tactics were infamous, but his troops were instrumental in getting the South to surrender. After the war, Sheridan spent most of his time out West. He was quoted as saying that “the only good Indian is a dead Indian,” although he denied ever having said this. Regardless, he did wage war against any number of tribes. He developed a special love for Yellowstone National Park, and he personally lobbied Congress to keep it pristine. By the time he died in 1888, Sheridan was considered a national hero. His name ended up on countless streets, cities, and other place names across the United States.
