Donelson at once became, like Grant, a name to conjure with. The fact that the Union had at last won a fight in which the numbers neared, and the losses much exceeded, those at Bull Run itself, the further fact that this victory made a fatal breach in the defiant Southern line beyond the Alleghanies, and the delight of discovering another, and this time a genuine, hero in "Unconditional Surrender Grant," all combined to set the loyal North aflame with satisfaction, pride, and joyful expectation. Great things were expected in Virginia, where the invasion had not yet begun. Great things were expected in the Gulf, where Farragut had not yet tried the Mississippi. And great things were expected to result from Donelson itself, whence the Union forces were to press on south till they met other Union forces pressing north. The river campaign was then to end in a blaze of glory. Donelson did have important results. Johnston, who had already abandoned Bowling Green for Nashville, had now to abandon Nashville, with most of its great and very sorely needed stores, as well as the rest of Tennessee, and take up a new position along the rails that ran from Memphis to Chattanooga, whence they forked northeast to Richmond and Washington and southeast to Charleston and Savannah. Columbus was also abandoned, and the only points left to the Confederates anywhere near the old line were Island Number Ten in the Mississippi and the Boston Mountains in Arkansas. But the triumphant Union advance from the north did not take place in '62. Grant was for pushing south as fast as possible to attack the Confederates before they had time to defend their great railway junction at Corinth. But Halleck was too cautious; and misunderstandings, coupled with division of command, did the rest. Halleck was the senior general in the West. But the three, and afterwards four, departments into which the West was divided were never properly brought under a single command. Then telegrams went wrong at the wire-end advancing southwardly from Cairo, the end Grant had to use. A wire from McClellan on the sixteenth of February was not delivered till the third of March. Next day Grant was thunderstruck at receiving this from Halleck: "Place C. F. Smith in command of expedition and remain yourself at Fort Henry. Why do you not obey my orders to report strength and positions of your command?" And so it went on till McClellan authorized Halleck to place Grant under arrest for insubordination. Then the operator at the wire-end suddenly deserted, taking a sheaf of dispatches with him. He was a clever Confederate. Explanations followed; and on the seventeenth of March Grant rejoined his army, which was assembling round Pittsburg Landing on the Tennessee, near the future battlefield of Shiloh, and some twenty miles northeast of Corinth.
