Sallie Ann Jarrett was the canine mascot of the 11th Pennsylvania Infantry, accompanying the soldiers throughout nearly the entire American Civil War, until she was killed in action in February 1865. Sallie, as the men would come to call her, was born in the spring of 1861 and was described by Colonel Richard Coulter as "a brindle, bull-terrier, of a fine breed," who "showed marks of blood." Her actual breed was American Pitbull. She was given to Capt. William R. Terry of Company I in May of that year by a resident of West Chester, Pennsylvania, where the regiment was training at Camp Wayne, on the town's former fairgrounds. The men named the pup in honor of two people, a young lady whom they admired and their original commanding officer, Colonel Phaon Jarrett.
