On July 23, 1863, General John Hunt Morgan entered Guernsey County with 600 Confederate cavalrymen, the remnant of a 2,000-man diversionary raiding force that had traversed Kentucky, Indiana, and southern Ohio. Morgan's forces halted in Old Washington on the morning of July 24 for rest and provisions. Three pursuing Union cavalry units under Brigadier General James M. Shackelford (1st and 3rd Kentucky, 14th Illinois) assembled on Cemetery Hill to the south and began firing on the Confederates in town. The raiders returned fire. In the exchange three Confederates were killed and several wounded. Eight were captured. Outflanked, Morgan proceeded northeast to Columbiana County, where he surrendered two days later. The three Confederate casualties are interred in the cemetery behind this site.
