Movements of Gen. Cadwallader--Capture of prisoners, &c.
Gordonsville, June 21.
--Gen. Cadwallader commanded the Federal troops approaching Harper's Ferry.
He has retired beyond Hagerstown, and Harper's Ferry is again held by our troops, consisting of 400 to 500 Marylanders.
Gen. Johnston is at Winchester.
Two prisoners of war, taken at Williams port, will go to Richmond to day. One is Lieut. Col. Bowman, of the Eighth Pennsylvania Regiment; the other Maj. Chase, connected with the Adjutant's Department, same Regiment.
They are under charge of Colonel Thomas, of the Maryland Volunteers, who carries the official report of the engagement at New Creek Depot.
Winchester now commands the whole Valley as a strategic position.
Gen. Johnston's movement from Harper's Ferry toward Martinsburg to meet the enemy, instead of being a retreat was an advance upon the enemy, who were approaching by Williamsport and Martinsburg.
Gen. Johnston's march was North.
He also sent a detachment to Romney, thus checkmating the Federal advance in both directions.
The Valley may now be considered safe.
