After graduating from Pineville High School, Hoskins was appointed to the U.S. Naval Academy graduating with the Class of 1921, and soon became a naval aviator. He served on the U.S.S. Memphis when Charles Lindbergh and his airplane The Spirit of St .Louis returned to the U.S. after their record-breaking flight across the Atlantic in 1927, and led the search for lost female aviation pioneer Amelia Earhart 10 years later. Captain Hoskins lost his right leg in the World War II action that earned him the Navy Cross, thereby earning the nickname, “The Peg-Legged Admiral.” He retired as a U.S. Navy Vice Admiral.
