In July of 1863, the Battle of Gettysburg raged for three days. Fifteen-year-old Tillie Pierce found herself in the middle of the action when she went to stay with family friends on a farm south of town. As the battle went on, the farm filled with wounded and dying soldiers, and Tillie helped feed and care for these men. Witness one of the most important battles of the Civil War up close with Tillie.
