Also in August, Confederate lieutenants George Baylor and Milton Rousss of Company B, 12th Virginia Cavalry, led a small raid attacking the W&P between Summit Point and Cameron's Depot, capturing eight Union soldiers, $4,000 in cash and food supplies. Following the Battle of Antietam in the 1862 Maryland Campaign, the Confederate States Army once again controlled the northern Shenandoah Valley for a brief time. The Confederates wanted to remove all the new rails laid down on the W&P, but due to a lack of wagons, were unable to take it. Therefore, General Robert E. Lee ordered Major General Lafayette McLaws' division to once again destroy the W&P in order to foil any attempt by McClellan to follow the Army of Northern Virginia. McClellan, meanwhile, on October 10, was making arrangements with the Baltimore & Ohio to reconstruct the W&P with heavier duty T-rails, locomotives and trains for planned future Union Army operations. The Baltimore & Ohio evaluated McClellan's plan, and replied that they did not have either the ties or rails to do the job, and that it would take at least six weeks to do the job, recommending that the Manassas Gap Railroad be repaired instead. McClellan then abandoned his plan to upgrade the W&P on October 12, and after a reconnaissance by Brigadier General A. A. Humphreys on October 19, the Union Army discovered that the W&P had been destroyed by the Confederates, making the upgrade plan even more unfeasible. In late October, General Robert E. Lee reported removal of the iron from the railroad for use elsewhere in the Confederacy. During the first half of 1863, Winchester, Virginia, the terminus of the W&P, was occupied by Major General Robert H. Milroy, who made no use of the railroad. Resistance to occupation in the Valley began to grow, and the 43rd Battalion Virginia Cavalry was stood up in that area under Major John S. Mosby, also known as the "Gray Ghost". On June 15, after a sweeping rout of Milroy in the Second Battle of Winchester, the Confederates once again controlled the northern Shenandoah Valley as they marched to the Potomac River during the Gettysburg Campaign. Two days later, "Captain T. B. Lee of the Corps of Engineers, C.S.A., was ordered to proceed to the lines of the Winchester & Potomac and the Baltimore & Ohio to collect any machinery, tools, rolling stock, or portions thereof which fell into Confederate hands.
