On 2 October 1918, during the Ypres-Lys offensive, French forces were cut off from supplies. Capt Francis F. Mulcahy, USMC, and his observer, Sgt Thomas L. McCullough, flew four successful missions to drop food for the French. They came under intense enemy ground fire. Here, Sgt McCullough is depicted leaning over the side of the aircraft, sighting his drop. For this action, Capt Mulcahy received the Navy Distinguished Service Medal. McCullough was awarded the Navy Cross.
