Cato Howe was an enslaved African American Black Patriot spy and courier during the American Revolution. Cato's enslaver, Hercules Mulligan, gathered intelligence through his personal connections as well as clients at his New York City tailoring shop, and Cato carried the information on horseback to Continental Army officers and other revolutionaries, including Alexander Hamilton and George Washington, and often through British-held territory. Cato's messages are credited with likely saving Washington's life on two occasions. Other than his intelligence activities with Mulligan, little definite information about Cato is available, though an excavation of his home after the war provides historians with more information about his life after the war.
