The 7th Ohio Infantry Regiment was an infantryregiment formed in northeastern Ohio for service in the Union Army during the American Civil War. It served in the Eastern Theater in a number of campaigns and battles with the Army of Virginia and the Army of the Potomac, and was then transferred to the Western Theater, where it joined the Army of the Cumberland besieged at Chattanooga. It was noted for its holding the high ground at the center of the line at Antietam as part of Tyndale's 1st Brigade, Greene's 2nd Division of Mansfield'sXII Corps.[1] It is of the 7th regiment that a war historian wrote, "All in all, considering the number of its battles, its marches, its losses, its conduct in action, it may be safely said that not a single regiment in the United States gained more lasting honor or deserved better of its country than the Seventh Ohio Volunteer Infantry."
