And is this war for the Union indeed a failure? Let our many and well-fought battles upon the ocean and the land answer the question. Let a country nearly as large as half of Europe, taken from the rebels since the war commenced, respond. Let Shiloh, and Donelson, and Gettysburg and Vicksburg, and Port Hudson, and New Orleans, and the Mississippi from its source to its mouth, answer. Why, this wretched calumny had scarcely been uttered by the McClellan Convention, when Sherman, the great commander, and his army had washed out the accusation in the blood of the vanquished, and unfolded our banner at Atlanta, the grand military strategic centre of Georgia, never to be recalled. And while the shouts of the great victory in Georgia were still sounding in our ears, Oppequan responded to the thunders of Atlanta, and the heroic Sheridan, after a decided victory, was driving the rebel army from the valley of Virginia. Was Sherman's campaign from Memphis and Nashville to Chattanooga, and from Chattanooga to Atlanta, a failure? Why, that campaign is unsurpassed in history. Was Grant's Potomac advance a failure? What, the hero of the great campaign of the West, terminating with the capture of Vicksburg and its garrison, not know, or do his duty! Was the victory of the Wilderness a failure, or the destruction in successive battles of one third of Lee's army, together with the seizure of the great Weldon Railroad, or the repulse there of the Confederate attack--were these failures? Recollect, Grant was Lieutenant-General, subordinate only to the President and Secretary of War, in planning the whole campaign, and, while too much credit cannot be given to the heroic Sherman and noble Sheridan, and their gallant armies, yet, it must be remembered, that their great victories and strategic military movements are but a part of Grant's plan--_concentrating_ the three armies of the Potomac, the Shenandoah, and the West, so as to seize and hold all the roads connecting with Richmond, and capture the Confederate army and government.
