Hopkinsville, Ky., was this day captured by a force of rebel guerrilla cavalry, under the command of Colonel A. R. Johnson. A quantity of ammunition and a number of rifles fell into their hands. Colonel Johnson issued a notice to the inhabitants of the town and its vicinity, informing them that he occupied the town and had taken the arms, etc., as a confederate soldier; and that if any Southern man or his property should be molested on account of his visit, he would retaliate on the Union men of the place.

The Richmond (Va.) Examiner of this date, speaking editorially of the approaching session of the rebel Congress, among other things, said: “It will be for Congress to repair, as it best can, the mischief done the public service by a weak and impracticable executive; to look at the reduction of our forces in the field; the decay of military discipline; the demoralization of our armies, and the jeopardy to which our cause has been put by a long course of trifling conduct, childish  pride of opinion, unworthy obstinacy, official obtuseness, conceit, defiance of public opinion, imperiousness and despotic affectation on the part of those intrusted with the execution of the war.”
The evacuation of Harrison's Landing, on the James River, Va., by the army of the Potomac, which commenced on the eleventh instant, was this day completed.--(Doc. 184.)
