Abram (or Abraham) Sanders[1] Piatt (May 2, 1821 – March 23, 1908) was a wealthy farmer, publisher, poet, politician, and soldier from southern Ohio who served as a general in the Union Army during the American Civil War.

In 1864, he and his brother constructed the Piatt Castles, two sprawling chateaux near West Liberty, Ohio, that are still used today for weddings, meetings, retreats, and other social gatherings.

His father was a Federal Circuit Judge and entrepreneur engaged in land development and flat boat trade in Cincinnati, who moved his family to Logan County in 1828.

A grief-stricken Abram became the colonel of the three-months' 13th Ohio Infantry Regiment on April 30, leaving his children in the care of a servant and his other family members.

During the fall and winter months, Piatt's Zouaves were on picket and scouting duty, and engaged in occasional skirmishing with guerrillas.

During the Maryland Campaign in the fall of 1862, Piatt and his regiment were detached from the Army of the Potomac and served in the Defenses of Washington, thereby missing the Battle of Antietam on September 17.
