"Sallie," was the regimental mascot for the 11th Pennsylvania Volunteer Infantry. Given to 1st Lt William R. Terry as a four-week old puppy, Sallie grew up among the men of the regiment. Sallie followed the men on marches and to the battlefield. At the Battle of Gettysburg, the dog got separated from the unit. Unable to find her way, Sallie returned to the Union battle line at Oak Ridge, where she stood guard over the dead and wounded. The dog continued her faithful service through February, 1865, when she was struck by a bullet to her head in the battle of Hatcher's Run, Virginia. She was buried on the field of battle. For her devotion to the men, Sallie is memorialized at the 11th Pennsylvania monument erected at Gettysburg.
