On June 28, 1863, Confederate cavalry from the mountains of West Virginia conducted a daring raid in unfamiliar enemy territory to destroy a pair of the Northern Central Railway's wooden railroad bridges over the Conewago Creek just south of York Haven in northeastern York County, Pennsylvania. The map shows the likely route, pieced together from surviving Confederate and civilian accounts, as well as from studying the postwar damage claims filed with the court system. These sworn testimonies were from farmers and residents who were trying to recoup their losses in horses and property taken by the Rebels.
