Side A: Camp Ripley 1861-1864. With news of hostilities at Fort Sumter in South Carolina, Ripley men formed one of Ohio's first military units and established Camp Ripley on what was the 12-acre Ripley Fairgrounds. Chosen as Captain was West Point graduate Jacob Ammen. His unit would be a saving force for Ulysses S. Grant's troops at Pittsburg Landing raising him to the rank of Brigadier General. Soon barns and buildings became military quarters, and tents dotted the landscape from William Street to Maplewood Cemetery. Camp Ripley, also known as Camp Ammen, served as a regional mustering point and military drilling location. Ripley gained distinction as being the only town in the United States to have soldier's organizations fighting from the Rocky Mountains to the Atlantic Ocean. Side B: Camp Ammen 1861-1864.
