Battle of Gettysburg
The regiment was commanded by Lieutenant Colonel Edward Salomon. It brought 347 men to the battle, of whom 4 were killed, 19 wounded, and 89 missing. Second Lieutenant Ferdinand Babst was mortally wounded and Captain Emil Frey and Lieutenant Eugene Hepp captured.
According to the account of Lt. Col. Salomon, "...it happened that my regiment, being the center of the whole line, was the last to leave the field. I received orders to cover our retreat through the town with my own regiment, the Eighty-Second Illinois and the Sixty-First Ohio. These two regiments, under my command, were the last to enter the town in which the greatest confusion reigned. Artillery, ammunition wagons, ambulances, provision trains, disorganized troops, wounded soldiers carried along by the ambulance corps thronged the narrow streets of the town. The retreat became a rout. My two regiments drove the men forward. I guarded the cross streets as much as possible, until I finally ran into a cul-de-sac, where I was compelled to have a heavy, tight board fence knocked down to make it possible to proceed. That accomplished, we had to pass through an enfilading fire of musketry until we gained the peach orchard (at the northern base of Cemetery Hill)."
