Gouverneur K. Warren
In September 1864, Union Lt. Gen. Ulysses S. Grant planned simultaneous attacks against both flanks of Gen. Robert E. Lee's Confederate army. The eastern attack would be carried out by the Army of the James under Maj. Gen. Benjamin Butler against the Confederate works at Chaffin's Farm. The western attack was to be carried out by the Union V Corps under Maj. Gen. Gouverneur K. Warren and a cavalry division under Brig. Gen. David McM. Gregg with units from the IX Corps and II Corps in support.
