As Colonel Porterfield's Virginians fled past here, surgeons quickly began helping the injured, using the church on the left side of the street as a hospital. James E. Hanger of the 14th Virginia Cavalry was among the Confederate casualties treated there after a cannonball crashed into a stable near the intersection of Main and Pike streets and struck his left leg. Doctor James Robinson of the 16th Ohio Volunteers amputated Hanger's leg about seven inches below his hip, one of the first of approximately 60,000 amputations during the war. Hanger remained in Philippi until he was sent to the prisoner-of-war camp at Camp Chase in Ohio, and about three months after the battle he was sent home to Mount Hope, Va. His wounding began a medical revolution: unhappy with his uncomfortable false leg, he patented a prosthetic in 1871 with a joint at the knee and a hinge at the ankle, formed Hanger Orthopedics, and helped bring about some of the first practical artificial limbs, with the company still producing prosthetics today.
