 After initially trapping this rolling stock on the Virginia-controlled portion of the Baltimore & Ohio, Jackson immediately "helped himself to four small locomotives not too heavy for the flimsy flat-bar rails of the Winchester and Potomac Railroad, and had them sent to Winchester" where they were disassembled near Fort Collier, mounted onto special dollies and wagons, and hauled by 40-horse teams "down the Valley turnpike to the [Manassas Gap] railroad at Strasburg".Eventually almost all of the B&O locomotives and most of the railroad cars were taken to the Manassas Gap Railroad.During the summer of 1861, the Manassas Gap Railroad became the first railroad in American history to move troops to a major battle.
