LOUISVILLE, November 6, 1862.

Major-General ROSECRANS:

The engineer of bridge force reports that a small party of rebels were at Richland Station this a.m.,and that mounted men have been seen by the carpenters to-day in numbers. The whole country from Richland to Gallatin has been occupied by bands of mounted men, who will cut off working parties and destroy their work unless a sufficient force is placed on the line. So large is this force of rebels that, in my opinion, there should, for the present, be placed a large force at Gallatin and at Tunnel Hill, with sufficient mounted men to intimidate them. I understand that no troops are on the line below Mitchellsville. The turnpike is too far from the railroad to enable troops by that line to protect the railroad. Can a guard be sent to Richland?

Major General W. S. ROSECRANS:

bridge men are at work 2 miles beyond Mitcellsville Station. Officer commanding forces at that place cannot send a guard to protect bridge party. Will it be safe to send the carpenters in advance of the troops? One bridge, 6 miles beyond Richland, was safe on Monday, and two, 4 miles, were partially burned. If the line can be occupied at once by troops these may be saved. Answer.

Major-General ROSECRANS:

General Wright went to Lexington. Heard he had gone to Cincinnati.

There are stragglers and deserters and convalescents, &c., but cannot get transportation, as all is used for your commissary stores. Will want regiment of cavalry, say Eighth Kentucky Cavalry, besides Seventeenth Kentucky ; wish them sent to Hopkinsville.
