It was not without well-meditated reasons that Mr. Lincoln had so long kept McClellan in command of the Army of the Potomac. He perfectly understood that general's defects, his want of initiative, his hesitations, his delays, his never-ending complaints. But he had long foreseen the difficulty which would and did immediately arise when, on November 5, 1862, he removed him from command. Whom should he appoint as McClellan's successor? What officer would be willing and competent to play a better part? That important question had also long been considered; several promising generals had been consulted, who, as gracefully as they could, shrank from the responsibility even before it was formally offered them. The President finally appointed General Ambrose E. Burnside to the command. He was a West Point graduate, thirty-eight years old, of handsome presence, brave and generous to a fault, and McClellan's intimate friend. He had won a favorable reputation in leading the expedition against Roanoke Island and the North Carolina coast; and, called to reinforce McClellan after the Peninsula disaster, commanded the left wing of the Army of the Potomac at Antietam. He was not covetous of the honor now given him. He had already twice declined it, and only now accepted the command as a duty under the urgent advice of members of his staff. His instincts were better than the judgment of his friends. A few brief weeks sufficed to demonstrate what he had told them--that he "was not competent to command such a large army." The very beginning of his work proved the truth of his self-criticism. Rejecting all the plans of campaign which were suggested to him, he found himself incapable of forming any very plausible or consistent one of his own. As a first move he concentrated his army opposite the town of Fredericksburg on the lower Rappahannock, but with such delays that General Lee had time to seize and strongly fortify the town and the important adjacent heights on the south bank; and when Burnside's army crossed on December 11, and made its main and direct attack on the formidable and practically impregnable Confederate intrenchments on the thirteenth, a crushing repulse and defeat of the Union forces, with a loss of over ten thousand killed and wounded, was the quick and direful result.
