Arriving at Gettysburg from Emmitsburg July 1, 1863, the 25th and 75th Ohio Infantry advanced beyond the town and, under a heavy cannonade, took position here, supporting Battery G, 4th U.S. Artillery. During July 2 and 3, they held an advanced line on East Cemetery Hill, and early July 4 led the advance into the town.
