In the spring of 1864, Grant had been appointed to command all Union armies. Grant's plan to end the war had several parts. Union General William Tecumseh Sherman's Atlanta Campaign and Grant's Overland Campaign were supported by other campaigns. They were all intended to keep Lee from reinforcing his main army. George Meade was still in (nominal) command of the Army of the Potomac, but there was little doubt Grant was in direct control of the army's movements.
