I must inform him that on the night of the 14th I received orders by telegraph from Major-General Rosecrans to send two regiments toward Clarksville, and then south to Cumberland River, to co-operate with General Negley in capturing of dispersing guerrillas. The command started at 3 o'clock a. m. on the 15th, and has not yet returned. When last heard from, it was about 2 miles from Cumberland River and 40 miles from this point. During the whole time they have been without tents or baggage and in the day and night, but in good spirits. lieutenant-Colonel McKee, Fifteenth Wisconsin, commanding had captured a considerable numbers and provisions collected for the rebel army. I hope the command will be here to-day, and I shall march for Nashville to-morrow.

Hoping that the delay has occasioned no detriment to the public service,

Your obedient servant,

W. P. CARLIN,

Colonel Thirty-eighth Illinois Volunteers, Commanding .
