Sherman, in his official report, gave his officers and men due credit for their "patience, cheerfulness, and courage." "For long periods," he said, "without regular rations or supplies of any kind, they have marched through mud and over rocks, sometimes barefooted, without a murmur. Without a moment's rest after a march of over four hundred miles, without sleep for three successive nights, we crossed the Tennessee, fought our part of the battle of Chattanooga, pursued the enemy out of Tennessee, and then turned more than a hundred and twenty miles north, and compelled Longstreet to raise the siege of Knoxville." Congress soon passed a resolution of thanks to Sherman and his army for their "gallant and arduous services in marching to the relief of the Army of the Cumberland, and for their gallantry and heroism in the battle of Chattanooga, which contributed in a great degree to the success of our arms in that glorious victory." The grade of lieutenant-general was now revived in the army, and bestowed upon Grant. He wrote Sherman at once to "express my thanks to you and McPherson, as _the men_ to whom, above all others, I feel indebted for whatever I have had of success. How far your advice and suggestions have been of assistance, you know. How far your execution of whatever has been given you to do entitles you to the reward I am receiving, you cannot know as well as I do." And Sherman wrote back: "I believe you as brave, patriotic, and just as the great prototype Washington; as unselfish, kind-hearted, and honest as a man should be; but the chief characteristic in your nature is the simple faith in success you have always manifested, which I can liken to nothing else than the faith a Christian has in his Saviour. "This faith gave you victory at Shiloh and Vicksburg. Also, when you have completed your best preparations, you go into battle without hesitation, as at Chattanooga--no doubts, no reserve; and I tell you that it was this that made us act with confidence. I knew, wherever I was, that you thought of me, and if I got in a tight place you would come--if alive." Sherman at this time was put in command of the military division of the Mississippi, with Schofield, Thomas, McPherson, and Steele under him. Grant was to conquer Robert E. Lee and his large army at the East; and Sherman, Joseph E. Johnston's army at the West and South. Supplies were at once gathered by Sherman at Chattanooga for one hundred thousand men, which would necessitate one hundred and thirty cars, of ten tons each, to reach that city daily. Confederate raids under Forrest and others were frequent; but, as in the case of Grant, nothing could deter Sherman. On May 5, 1864, the great army started for Atlanta, Ga., prepared to fight its way. The men fought bravely at Resaca, at Allatoona Pass, and elsewhere.
