LOUISVILLE, July 29, 1862.

Morgan is at Livingston or Sparta, resting their party for another raid. The rebels are recruiting a larger force in Tennessee. I have over 2,000 cavalry ready for arms, &c., under orders issued to me last week by War Department. I will soon have between 3,000 and 4,000 cavalry, if I can get equipments and arms. I seize my horses from secessionists by written authority from the Government. Could not get horses otherwise. Can we not catch Morgan? Shall I move into East Tennessee; leave the guerrillas to be destroyed by other forces? We ought not to give up that part of kentucky to them. If I had any officers to aid me could get on. Can I have General Johnson? Don't you want General G. Clay Smith?

HEADQUARTERS, Huntsville, July 30, 1862.

General BOYLE, Louisville:

I am gratified to hear that you are getting so considerable a cavalry force. In the phase the war is assuming it is daily becoming more important. If you have four or even three regiments the best disposition of them to protect Kentucky against any more Morgan raids would be to place two in the vicinity of Cookville, Tenn., and the rest at Columbia, Ky. The former would be in a position to act in conjunction with the latter and with the movements I am making in Tennessee. After all, the security of Kentucky depends on depriving the enemy of any resting place in Tennessee. You cannot operate advantageously toward East Tennessee except in conjunction with the troops moving from Nashville or those at Cumberland Gap, and the former would be best at this time.

If your cavalry is not sufficient to divide in the way I mention, Columbia or Glasgow is the best position for it. With the brigades fortified with stockades as I have directed nearly your whole force can be used in a body wherever required. I cannot spare General Johnson, as he is in command of the cavalry and other troops about Murfreesborough. Let me know what effective cavalry force you now have and where posted.

D. C. BUELL,
Major-General.

LOUISVILLE, July 30, 1862.

Morgan went from Livingston, taking road to Sequatchie Valley, saving his intention was to go to Knoxville. He left 400 or 500 10 miles southward of Livingston. He declared his purpose to return to Kentucky. Two hundred and fifteen of Morgan's recruits, from Owen and other counties, were overtaken by Major Bracht, Eighteenth Kentucky, and Home Guards, at Flemingsburg, and routed, 13 killed, 78 captured; pursuing the others. We had 3 wounded. I shall send Ninth Pennsylvania Cavalry into Clinton and Wayne Counties to protect people at election. The regiment turns out to be a poor concern. Metcalfe's regiment cavalry (three years) nearly completed. Almost 2,000 recruits for new cavalry regiments. I can't get horses.

Major-General BUELL.
