When the United States entered World War I in 1917, George Vaughn Seibold, 23, volunteered, requesting assignment in aviation. He was sent to Canada where he learned to fly British planes since the United States had neither an air force nor planes. Deployed to England, he was assigned to the British Royal Flying Corps with 148th Aero Squadron. With his squadron, he left for combat duty in France. He corresponded with his family regularly. His mother, Grace Darling Seibold, began to do community service by visiting returning servicemen in the hospitals.
