Ohio men fought in every major battle of the war. Within forty-eight hours of President Abraham Lincoln's call for volunteers in April 1861, two Ohio infantry regiments already had departed for Washington DC. An Ohio brigade protected the Union army's retreat at the First Battle of Bull Run in 1861. Ohio regiments also helped secure Kentucky and West Virginia for the North. They participated in the Battles of Fort Donelson, Gettysburg, Antietam, Fort Wagner, Shiloh, Chickamauga, and many others. Approximately 11,237 Ohio soldiers died from wounds received on the various battlefields, while another 13,354 men perished from diseases. Eighty-four of every one thousand Ohio men who served died in the war. Another forty-four for every one thousand deserted. This was one of the lowest desertion rates in the Northern states.
