The enemy was pursued along the road to Dalton to a gorge about three miles from the town. The railroad runs through this gorge, formed in Rocky Face Ridge or Buzzard’s Roost, and the position occupied here by the rebels appeared to be almost impregnable. An advance on the 24th had driven the enemy from all the ridge north of the creek, but on the retirement of the Union troops at night, it was reoccupied by the rebels, who, being now thoroughly aroused to their danger, recalled Claiborne’s, Stevenson’s, and other divisions to aid in repelling their assailants. At about eleven o’clock, A. M., on the 25th, soon after all the forces comprising the expedition had arrived, the Union troops, in long blue lines, moved in splendid order upon the enemy’s works. The skirmishers became at once closely engaged in the woodland. The advance was steady and rapid, clearing the enemy from the ridge as it proceeded. The object of the reconnoissance was accomplished; the enemy, in overwhelming force, was found to be strongly posted in the gorge, and, accordingly after much heavy skirmishing, the Union forces were ordered to retire. Some rebel cavalry attempted to pursue them, but were soon driven out of sight. The capture of Tunnel Hill, and the other important operations of the expedition, had been accomplished with a loss of about seventy-five killed and two hundred and fifty wounded. The rebels suffered much more severely. THE CAPTURE OF UNION CITY, TENN. MARCH 25, 1864. The Federal posts in West Tennessee and Kentucky, were, in consequence of the withdrawal of the forces under Generals Sherman and A. J. Smith from Vicksburg, left much exposed, and General Forrest did not hesitate to avail himself of the opportunity thus presented of successfully attacking them. He accordingly concentrated and reinforced his command, and, on the 23d of March, started, with about five thousand men, from Jackson, Tenn., and reached Union City on the twenty-fourth. Here he found Colonel Hawkins with the Eleventh Tennessee Union cavalry, consisting of about four hundred and fifty men. At first Colonel Hawkins refused to surrender. His subordinate officers were confident of their ability to hold out till succor arrived, which they believed would soon reach them. Colonel Hawkins was, however, less sanguine, and finally surrendered to the enemy after a slight assault, who captured beside the garrison, two hundred horses and five hundred small arms. Hardly had the place been surrendered, when General Brayman, from Cairo, advanced to its relief. When within six miles from the post, he learned that its surrender had just taken place, and marched back with the shameful tidings to Cairo. THE ATTACK OF PADUCAH, KY. MARCH 26, 1864.
