The Battle of the Wilderness, May 5-7, 1864, began what proved to be the start of the final campaign against the Army of Northern Virginia. Here Meade’s Army of the Potomac, numbering approximately 118,000 troops, fought the Confederate defenders of Richmond. Lee had about 62,000 men with him, while an additional 30,000 under Gen. P. G. T. Beauregard held the Richmond-Petersburg area. The battle resulted in a fearful loss of men on both sides, although the armies remained intact. This was followed by a series of fierce engagements around Spotsylvania Court House from May 8 to 21. Failing to destroy the Army of Northern Virginia in these battles, Grant moved the Army of the Potomac to the east of Richmond. It was his hope that he would outflank the Confederate defenders by persistent night marches. Lee was not to be so easily outguessed, however. After minor battles at the North Anna River (May 23) and Totopotomoy Creek (May 29), Grant arrived at Cold Harbor, about 8 miles northeast of Richmond, but Lee’s army still stood between him and that city. On June 3, 2 days after he arrived at Cold Harbor, Grant ordered a direct frontal assault against the Confederate lines. He was repulsed with heavy losses—about 7,000 men. “I have always regretted that the last assault at Cold Harbor was ever made,” Grant would write many years later. By the end of the first month of Grant’s campaign, both sides had suffered heavy casualties, but the North’s ability to refill its depleted ranks was greater than the South’s. Lee’s offensive strength had been sapped. From the Battle of Spotsylvania Court House until the end of the war, except for counterattacks and the lunge at Fort Stedman during the siege of Petersburg, the Army of Northern Virginia was a defensive weapon only. After Cold Harbor, Grant decided to turn quickly to the south of Richmond and isolate the city and the defending troops by attacking Petersburg and cutting the railroads that supplied them. Lee knew he could not allow this to happen. “We must destroy this army of Grant’s before he gets to James River,” he told one of his generals. “If he gets there, it will become a siege, and then it will be a mere question of time.” STRATEGIC PETERSBURG According to the United States census of 1860, Petersburg was a city of 18,266 people. It was situated on the southern bank of the Appomattox River about 8 miles from City Point, where the Appomattox joins the James, and 23 miles south of Richmond. As the war progressed and the territory to the north and east was shut off, Richmond became increasingly dependent on Petersburg for supplies. Through it passed a constant stream of war materials and necessities of life from the South to sustain the straining war effort. In short, Petersburg was a road and rail center of vital importance to the Confederacy, and its capture would almost certainly lead to the abandonment of Richmond.
