October 19th, 1863, General Grant assumed full command of the Departments of Tennessee, the Cumberland, and Ohio, Thomas holding under him the first, and Sherman the second. After the desperate battle of Chicamauga, Thomas followed Rosencranz to Chattanooga, and the rebels invested the place. In October, Rosencranz was relieved. Grant arrived on the 18th, and found the enemy occupying the steep and rocky Missionary Ridge and Lookout Mountain, on whose summit they sat like eagles. Grant had under him General Thomas, the invincible Sheridan, Hooker--who, as a hard-fighting corps-commander, was without an equal--Howard and Blair. This battle of Chattanooga, in which the Union army charged with irresistible strength, and the storming of Lookout Mountain, formed, as has been said, the most dramatic scene of the war. There was desperate fighting above the clouds, and advancing through the mist, made denser by the smoke of thousands of guns. The Union loss in this battle was 5286 killed and wounded, and 330 missing; that of the Confederates about the same, but losing in prisoners 6242, with forty cannon. Thus Tennessee was entirely taken, in gratitude for which President Lincoln issued a proclamation, appointing a day of thanksgiving for this great victory. In the July of this year, John Morgan, the guerilla, made a raid, with 4000 men, into Ohio--not to fight, but to rob, burn, and murder. He did much damage; but before he could recross the river, his men were utterly routed, and the pious Colonel Shackelford announced in a despatch, “By the blessing of Almighty God, I have succeeded in capturing General John Morgan, Colonel Chike, and the remainder of the command.” President Lincoln, when informed soon after of the death of this cruel brigand, said, “Well, I wouldn’t crow over anybody’s death, but I can take this as resignedly as any dispensation of Providence.”
