Early in the Korean War, U.S. Air Force Captain John Walmsley, Jr., of Baltimore, Maryland, volunteered to fly nighttime bombing missions against communist truck and train convoys carrying war materiel from China into North Korea. His Douglas B-26 Invader carried an 80-million candlepower arc light that improved night vision but also made the aircraft an easy target for enemy fire. On the night of September 14, 1951, about 100 miles inside North Korean territory, Walmsley and his three-man crew found an armed train moving south and damaged it through several bombing and strafing passes. When a second B-26 arrived, Walmsley kept flying at low altitude directly over the train to illuminate it with his arc light, enabling the other bomber to destroy the train. Anti-aircraft fire then badly damaged Walmsley’s aircraft, which began leaking fuel and caught fire. He tried to fly the B-26 to safety, but it crashed in a mountainous region, killing Walmsley and two crewmen, while a third survived and was captured. For their extraordinary heroism, each member of the crew received the Distinguished Flying Cross, and Walmsley was awarded the Medal of Honor posthumously, presented to his widow.
