General Rosecrans had succeeded McClellan as ranking officer in West Virginia, but it was not until the latter part of September that the region was made a department and he was regularly assigned to command. [Footnote: Official Records, vol. v. pp. 604, 616, 647.] Meanwhile the three months' enlistments were expiring, many regiments were sent home, new ones were received, and a complete reorganization of his forces took place. Besides holding the railroad, he fortified the Cheat Mountain pass looking toward Staunton, and the pass at Elkwater on the mountain summit between Huttonsville and Huntersville. My own fortifications at Gauley Bridge were part of the system of defensive works he had ordered. By the middle of August he had established a chain of posts, with a regiment or two at each, on a line upon which he afterwards marched, from Weston by way of Bulltown, Sutton, and Summersville to Gauley Bridge.
