By this brilliant and important victory Grant's fame sprang suddenly into full and universal recognition. President Lincoln nominated him major-general of volunteers, and the Senate at once confirmed the appointment. The whole military service felt the inspiriting event.--_Nicolay and Hay, in "Life of Lincoln."_ The grasp of a great section of western Kentucky and Tennessee by the Northern armies, the capture of a stronghold that was thought impregnable, the forced surrender of a great army, and the bringing into public notice of a new commander who was destined to outshine all his fellows--these were the achievements of the short, vigorous campaign of Fort Donelson. There were two great battle-grounds of the Civil War, nearly a thousand miles apart--Virginia and the valley of the great river that divides the continent--and the two definite objects of the Northern armies during the first half of the war period were to capture Richmond and to open the Mississippi. All other movements and engagements were subordinate to the dramas of these two great theaters, incidental and contributory. The South, on the other hand, except for the early threatening of Washington, the Gettysburg campaign, the raid of Morgan in Ohio, and the expeditions of Bragg and Hood into Kentucky and Tennessee, was on the defensive from the beginning of the war to the end. In the East after the initial engagement at Bull Run "all was quiet along the Potomac" for some months. McClellan had loomed large as the rising hero of the war; but McClellan did not move with the celerity that was expected of him; the North became impatient and demanded that something be done. But while the public was still waiting there were two occurrences in the West that riveted the attention of the nation, sending a thrill of gladness through the North and a wave of depression over the Southland. These were the fall of Fort Henry and of Fort Donelson. After Missouri had been saved to the Union in spite of the disaster at Wilson's Creek in August, 1861, a Union army slowly gathered in southern Illinois. Its purpose was to dispute with the Confederates their hold on Kentucky, which had not seceded, and to regain control of the Mississippi. To secure the latter end a flank movement was decided upon--to open the mighty river by moving up the Cumberland and Tennessee--the greatest flanking movement in the history of warfare. It began at Fort Henry and ended at Vicksburg, covered a year and five months, and cost tens of thousands of human lives and millions of dollars' worth of property--but it was successful.
