360 SOLDIERS AND SAILORS Hooker carried Lookout Mountain and Thomas captured the Ridge on No- vember 25th. In the latter operation Sheridan's division was the first to cross the crest, and it pressed the enemy's rear-guard until long after dark, seizing wagons and artillery. By his successful conduct in the West, Sheridan had now thoroughly established his military reputation. Grant, who had now become lieutenant-general, established his headquarters in Virginia in March, 1864. He was very badly off for an energetic command- er of cavalry there, and discussed the matter with General Halleck. The latter at once suggested Sheridan, remembering his splendid dash and bravery at Mis- sionary Ridge. " The very man ! " exclaimed the laconic Grant, and Sheridan accordingly became commander of the Cavalry Corps of the Army of the Potomac. Sheridan's progress during the campaign of 1 864 was like a whirl- wind. His troops covered the front and flanks of the infantry through the battle of the "Wilderness " until May 8th, when the greater part of the force was with- drawn, and next morning Sheridan started on a raid against the enemy's points of communication with Richmond. Getting within the Confederate lines he dashed upon the outworks of Richmond itself, where he took one hundred prisoners, and thence moved to Haxall's Landing, from which point he returned to the Northern army, having destroyed many miles of railroad track, besides trains and a great quantity of rations, and liberated Union soldiers. This expe- dition included repulses of the enemy at Beaver Dam and Meadow Bridge, and . the defeat of the enemy's cavalry at Yellow Tavern, where their best cavalry leader, J. E. B. Stuart, was killed. From May 27th to June 24th Sheridan was engaged in almost daily engagements and skirmishes, harassing the enemy, and, with that good fortune which sometimes attends the most daring soldiers, resist- ing all attempts to defeat or capture him. The Middle Department and the Department of West Virginia, Wash- ington, and Susquehanna were constituted the " Middle Military Division " in August, 1864, and General Grant put Sheridan in command of the same. He chafed for opportunities of further distinguishing himself and justifying his ap- pointment ; but the enemy, under General Early, had been reinforced, and for six weeks Sheridan was kept on the defensive near Harper's Ferry. At length, when Early's forces had been diminished, Sheridan expressed such confidence of success if he were allowed to attack, that Grant gave him permission in only two words of instruction, " Go in ! " Sheridan went in, attacking Early with great vigor, on September 19th, at the crossing of the Opequan. After a severe battle the enemy was routed ; Sheridan captured three thousand prisoners and five guns, and sent Early, as he expressed it, "whirling through Winchester." Next day President Lincoln, on Grant's recommendation, appointed the victorious soldier a brigadier- general in the regular army. Taking up the pursuit of Early in the Shenandoah Valley, Sheridan found him on the 20th strongly posted on Fisher's Hill, just beyond Strasbnrg. Quietly moving Crook's command through the wood, he turned the enemy's left on the 2 2d, and drove him from his stronghold, capturing sixteen guns.
