He was an American Spy. He volunteered to spy on British in New York. He would report back on crucial information from the British. He disguised himself as a schoolteacher. He knew if he was caught he would be executed. There is no proof to how he was caught.

He was hung by the British. His famous last words were, “I only regret that I have but one life to give for my country.”
