October 12.—This day, the rebel General Stuart’s cavalry, which had passed around the Union army of General McClellan, made good its escape across the Potomac at White’s Ford, near the mouth of the Monocacy River. During the day, General Pleasanton, with five hundred cavalry, harassed the rebel rear, and engaged them in a sharp skirmish, but with no material loss on either side.—(Doc. 5.)
—Considerable excitement was created in Gainsville, Texas, by the discovery of a secret organization of Unionists, whose object was said to be that of killing the secessionists, after which, they were to remove to Missouri, taking with them whatever property they could carry, and burn the remainder. The militia were called out, and arrested twenty-nine persons supposed to belong to the organization, two of whom were immediately hanged.—Houston News.
