At this time, we have only limited information on Thomas McCauley. He was just 18 when he joined the battery early in 1864 in Chicago. Just six months later, on July 14, he was wounded and “left in the hands of the enemy” at Tupelo, Mississippi. Medical records report that his right leg was amputated at the thigh, and it is believed that he died of his wounds.
