第三次チャタヌーガの戦い
In mid-1863 the Confederate government finally initiated an overall policy concerning railroads, and even then it was confined solely to aiding the war effort rather than shoring up the weakening economy of the Confederate States of America. New legislation allowed commandeering (under the name of "impressment"), which brought railroads and their rolling stock under the de facto control of the military. Meanwhile, Union victory in the Chattanooga Campaign gave the United States Military Railroad full control of the Nashville and Chattanooga Railroad which after repairs supplied the Atlanta Campaign.
