Gouverneur K. Warren
In August, the II Corps operated north of Petersburg, threatening Richmond and its railroads in the Second Battle of Deep Bottom. Simultaneously, Grant planned another attack against the Weldon. The V Corps supported by units from the IX Corps, II Corps, and a small cavalry division commanded by Brig. Gen. August Kautz, was chosen for the attack under the overall command of the V Corps commander, Maj. Gen. Gouverneur K. Warren. While the overall Confederate commander, Gen. Robert E. Lee, was observing at the Deep Bottom battle, Gen. P.G.T. Beauregard was the senior commander at Petersburg. Lt. Gen. A.P. Hill commanded the Third Corps, Beauregard's primary infantry force.
