The Federal 3rd Division of the Army of the Tennessee, commanded by Major Gen. Lew Wallace, was positioned by brigades along an east-west line to meet a Confederate attack expected from the north or northwest. The 3rd Brigade under Col. Charles Whittlesey, 20th Ohio Infantry, was in this area. This division withdrew to join the Shiloh engagement of Apr. 6, but arrived too late to engage until the following morning.
