Engagement on the Potomac.
A dispatch was received yesterday, at the War Department, announcing that nine Federal steamers had opened fire upon our batteries in the vicinity of Evansport
, on the Potomac
, and that a brisk engagement was going on at 11 o'clock. By later advices, we learned that the enemy withdrew from the contest in the afternoon, having probably got enough of it. The news served to excite the public mind to some extent, and efforts were made together store definite particulars; but all applications at the Department proved unsuccessful.
We were prepared to expect an early fight on the Potomac
, having previously received an intimation of the unmasking of our batteries, which the Federals
had been vainly endeavoring to ‘"locate."’
