Circa1865

Grant took command of Lincoln’s Army of the Potomac on March 17, 1864, now massed on Virginia’s Rapidan River and numbering 141,160 men. To oppose this invasion of Virginia, General Robert E. Lee’s strength was 50,403 muskets. His cavalry, artillery and supplies were all depleted, and his numerical strength in all arms did not exceed 64,000 as Grant began his march southward on May 4, 1864.

Grant’s Theory of Attrition

“General Grant’s theory of war was, “to hammer continuously against the armed force of his enemy, until, by mere attrition, there should be nothing left.”

Military genius, the arts of war, the skillful handling of troops, superior strategy, the devotion of an army of men, the noble self-denial of commanders, all must give way before the natural forces of “continuous hammering” by an army with unlimited reinforcements, an inexhaustible treasury, a well-filled commissariat, and all directed by a unanimous people.

The work of Lincoln’s war department was based upon the need for an army of a million men. Vast stores were accumulated. The US Congress, with reckless prodigality, continued to pass the most extravagant appropriations for organizing armies, and for maintaining the countless forces which constituted an invasion so vast, that it was hoped it would be invincible.

At the Wilderness, Grant’s onslaught overpowered two divisions and drove them back until Lee himself rode among his troops to rally them and reestablish his lines. In early June, Grant ordered an assault at Cold Harbor which was repelled with extraordinary slaughter, though he ordered a second attack in the afternoon which his men sullenly refused to obey.

Grant then pivoted toward the James River below Richmond to surprise and capture Petersburg, but was thwarted by Generals Beauregard and Wise, who had been reinforced with local militia and home guards. At this point Lee’s aggregate strength had increased to 78,400 men with which to oppose Grant, who had been reinforced and was now up to 192,160 troops.

Mr. Swinton, in his ‘History of the Army of the Potomac,’ estimates Grant’s losses at the Wilderness, Spottsylvania, North Anna and Cold Harbor battles at “above 60,000 men’ which included 3,000 officers, ‘while the loss of Lee did not exceed 18,000 men, of whom few were officers). This result would seem an unfavorable comment upon the choice of route by Grant, as McClellan two years prior attained the same point with trifling losses.

Grant had achieved no signal victory nor important success to offset his losses and had not defeated Lee on any of the campaign’s battlefields. The Army of Northern Virginia, not reinforced until it had reached Hanover Junction, and then only by 9,000 men, had repulsed every assault, and in the final trial of strength with a force vastly superior, had inflicted upon the enemy, in about an hour, a loss of 13,000 men.”
