This occurred on the second day of the Shiloh battle, April 7, 1862, on which day, after a heroic effort to breast Grant's overwhelming numbers, Beauregard withdrew from Shiloh to Corinth. This capture of Island Number 10 opened the Mississippi to Memphis, except for the single and, as it afterwards proved to be, the utterly ineffective position at Fort Pillow. General Halleck was fully informed of all that had happened. He knew that Pope's way was open down the Mississippi to Memphis, and that Memphis, scarcely at all defended, was within his easy grasp. He knew of course that Memphis was the westerly end of the new defensive line of the Confederates, and that its capture must compel them still further to retire toward the south, even should he fail or neglect to drive them from the Memphis and Charleston railroad line at Corinth, as he easily might have done with his utterly overwhelming force, and as Grant would undoubtedly have done if that vigorously aggressive general had been left in control of that splendidly equipped army. But Halleck sat still and pottered over "reports" that annoyingly paid no tribute to his genius and suggested no credit to him for the victory that had been won. Meanwhile Grant was losing time. The Confederates, foreseeing the inevitable loss of Memphis, which happened on the sixth of June, nearly two months after energy would easily have compelled it, were busily fortifying all defensible positions on the river below, especially at Vicksburg and Port Hudson, and thus making necessary one of the most strenuous and one of the bloodiest campaigns of the war, where scarcely any campaign at all would have been necessary but for the fact that a martinet officer, much too "scientific" and too "regular" for the practical purposes of war, was in authority over a man who knew not only how to plan campaigns but how to conduct them quickly to a successful conclusion. CHAPTER XXV FARRAGUT AT NEW ORLEANS There was still another man of splendid genius and capacity who about this time came to the front as a winner of victories for the Federal arms, and above all, as a man like Grant, who knew how to do things when officialism permitted him to act. Like Grant on the one side, and Lee on the other, Farragut was at first treated as a negligible factor in the war.
