The Miracle On Missionary Ridge

As far as the soldiers were concerned the new supply route was "the cracker line" because it brought boxes of the basic army ration, hardtack; and Grant got most of the credit for opening it simply because it happened a few days after his arrival. In his messages to the War Department, Grant was scrupulous to give the credit to Thomas and Smith, making it clear that the plan had been "set on foot before my arrival"; but he had automatically become a miracle worker when he captured Vicksburg and by now any good thing that happened in his jurisdiction was certain to be ascribed to him Besides, a new atmosphere had unquestionably come in with him General O.O. Howard, one of Hooker's corps commanders, spoke of it, later that fall, in a letter to a friend in the Senate: "This department was completely `out of joint' when we first arrived. A most complete & perfect want of system prevailed, from Louisville to Chattanooga. I can now feel the difference. . . . I cannot be too thankful for the policy that placed these three Depts. under Grant."
This was all very well, and after a long period in which he never seemed to get much recognition for what he had done, Grant may have found it pleasant to get a little too much; and yet, even though opening this cracker line was one of the decisive events of the whole Chattanooga campaign—it meant, in effect, that Bragg had gone over from the offensive to the defensive, although Bragg did not yet realize it—Grant still had problems.
The unhappy truth was that the army's whole transportation system-- that is to say, the huge array of horses and mules that pulled wagons, guns, and ambulances, without which the army could not travel—had been almost ruined by the blockade, and the damage could not be set right immediately. Montgomery C. Meigs, Quartermaster General of the army, had come out to Tennessee to do what he could to improve matters, and on October 25 he sent a gloomy report back to the War Department: "The animals with this army will now nearly all need three months rest to become serviceable. They should be returned to Louisville for this purpose. Hard work, exposure, short grain and no long fodder have almost destroyed them." It was quite true, as Grant pointed out to General Halleck, that steamboats now were running regularly between Kelley's Ferry and Bridgeport, "thus nearly settling the subsistence and forage questions"; the army was not going to starve. To restore the army's mobility would be another matter altogether.
It was at least beginning to be clear that the 25,000 men Lee was reported to be sending into East Tennessee were not coming. They never had been coming, because Lee simply did not have 25,000 men to spare. Yet even as this threat evaporated a new one appeared. On November 4, acting on a suggestion from President Davis, Bragg ordered Longstreet to take two divisions of infantry and some cavalry, leave the lines around Chattanooga, and move up the railroad toward Knoxville, with the injunction: "Your object should be to drive Burnside out of East Tennessee first, or better, to capture or destroy him." Bragg knew that Sherman was on the way to join Grant, and he seems to have hoped that Longstreet could dispose of Burnside and then get back in time to help Bragg meet any attack Grant's reinforced army might make. (At the very least, Longstreet's move might compel Grant to detach troops to help Burnside.) Longstreet, who had lost all confidence in Bragg, felt that the 12,000 infantry he would be taking were an utterly inadequate force, and he wrote bitterly that it was this army's sad fate "to wait till all good opportunities had passed and then in desperation to seize upon the least favorable one." With hindsight, it is easy to see that when he sent Longstreet away Bragg made a ruinous blunder; but in the first week in November, 1863, the move looked extremely ominous to the Federal authorities in Chattanooga and in Washington, partly because the size of Longstreet's force was grossly overestimated. Grant found himself obliged to meet a new crisis.
He hoped that Hooker could clear the Confederates off the west side of Lookout Mountain and then move up Lookout Valley in such a way as to compel Bragg to recall Longstreet, but at best this was a thin hope. All Grant could promise was that a real attack would be made after Sherman arrived. To all intents and purposes the Army of the Cumberland had no transportation system whatever; it was hopelessly stalled. The infantry, to be sure, could walk, but Grant confessed that it could go only as far "as the men can carry rations to keep them and bring them back." The artillery could not go at all. Using every expedient to provide teams, Thomas could move only one out of every six of the imposing array of cannon at his command. In mid- November the army was still paralyzed, and Grant told Halleck: "I have never felt such restlessness before as I have at the fixed and immovable condition of the Army of the Cumberland."
Not in all the war did Grant live through a more tantalizing situation. By sending away Longstreet and two divisions of infantry, Bragg had prepared the way for his own defeat; Grant knew it, knew that a hard blow well delivered must drive the Confederate army back into Georgia—and found himself utterly unable to strike. From Moccasin Bend to the end of Missionary Ridge, the Confederate army was in plain sight, its campfires making a crescent against the sky night after night, its picket lines so close that Northern and Southern boys fraternized daily in a most unwarlike manner; but Grant and Thomas and all of their men might as well have been north of the Ohio River for anything they could do about it.
