The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pride in presenting the Army Distinguished Service Medal (Posthumously) to Major (Air Corps) William Grover Benn (ASN: 0-21524), United States Army Air Forces, for exceptionally meritorious and distinguished services to the Government of the United States, in a positions of great responsibility with Headquarters, FIFTH Air Force, in the Southwest Pacific Theater of Operations, from 19 September 1942 to 18 January 1943. As Commanding Officer of the 63d Bombardment Squadron, 43d Bombardment Group, Major Benn’s planning and leadership brought remarkable achievement to his group as well as to his squadron. Despite interception and difficult flying weather, his combat crews fought their way over the target on 30 days of the period between 19 September and 18 November 1942. During this period 33 Japanese vessels were destroyed or severely damaged, and 18 enemy aircraft destroyed. This notable record was made without the loss of an airplane, and only three men were wounded. Major Benn’s squadron also was largely responsible for introducing low altitude bombing and proving it practicable. Later, as assistant to the Chief of Operations, Advance Echelon, Headquarters FIFTH Air Force, he continued to develop low altitude bombing, and by his tactical ingenuity, bold experimentation, and extensive planning of combat operations, contributed greatly to the success of the FIFTH Air Force in the New Guinea and New Britain areas. The singularly distinctive accomplishments of Major Benn and his dedicated contributions in the service of his country reflect the highest credit upon himself and the United States Army Air Forces.
