MOUNT VERNON, June 26, 1863-3.30 p. m.

GENERAL: I have just arrived at this place. Will turn the command over to Colonel Byrd, to take to Hickman, and proceed to Lexington, as directed by General Hartsuff. Major Dow, with 170 men, is still back. He will be in Loudon to-night. The number of pieces of artillery taken was ten, three at Lenoir's, two at Knoxville, and five at Strawberry Plains. The bridge at the latter place was guarded by 400 men and five pieces of artillery. We captured all the guns, 125 prisoners; killed their commanding officer and several privates. Our loss was only 1 wounded at that place, 1 killed and 2 wounded at Knoxville. Have lost some stragglers taken prisoners. The operator was taken the day we reached Knoxville. Have lost a number of horses.

LEXINGTON, June 28, 1863.

GENERAL: I was in the edge of the town limits. The force was 1,500 regular soldiers, and all the citizens were forced into the ranks. They had had pieces of artillery in position; the streets were barricaded with cotton bales; batteries protected by the same. We were engaged with the enemy for about one hour at long range at this place. General Buckner was absent at the time. He command East Tennessee, Southwestern Virginia, and Western North Carolina. Part of the troops at Knoxville were brought from Bristol the evening I arrived there. I was within 2 miles of the place from sundown until 8 o'clock the next morning.
