Mr. Seward to Mr. Adams.

No. 341.]

Sir: Just at the moment when the mail is about to close authentic information reaches the government that the insurgent forces which have been approaching and menacing Cincinnati and Louisville have receded, and are retreating in Kentucky. The alarm in that quarter has passed.

The press has already announced that the insurgent army, which has been threatening Washington, Baltimore, and Pennsylvania, evacuated Frederick on the 12th instant. I now give you a despatch which has just been received from Major General McClellan, which shows the position of the two armies at the present moment.

I am, sir, your obedient servant,

WILLIAM H. SEWARD.

Charles Francis Adams, Esq., &c., &c., &c.
