LOUISVILLE, July 21, 1862.

No information of Morgan since last dispatch. I have ordered General Smith to continue pursuit not allow Morgan to take position at Mill Springs. General Morgan telegraphs from the Gap that 1,100 Louisiana cavalry, to be re-enforced with artillery and infantry, are at Kingston. General Morgan says scouts from Morristown state Kentucky is to be invaded through Pound Gap. General Morgan has sent a regiment to Barboursville. I will send to London. There are rumors of bands in every part of the State.

Morgan at Somerset. He is moving from Somerset. My force pursuing. Colonel Wolford is on way for Somerset with 600 mounted men. May overhaul Morgan there, and detain him until pursuing force comes up. Morgan will go out by Mill Springs. He has been in retreat for three days' before my forces. He has the best mounted men in the world.

LOUISVILLE, July 21, 1862-10 p.m.

No information since my last as to Morgan. He is probably at Somerset. I have ordered my force to continue pursuit, and not allow him to remain at Mill Springs. General Morgan telegraphs from Cumberland Gap that 1,100 Louisiana cavalry, to be re-enforced with artillery and infantry at Kingston, Tenn., are to invade Kentucky. He says scouts state that Kentucky is to be invaded by Pound Gap. This may all be rebel lies. They have bands in many parts of this State. Many of the best men in the State believe there is preparation for a general uprising. I believe there is such purpose and plans.

Brigadier-General, Commanding.
