The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Silver Star to Colonel (Air Corps) Walter Campbell Sweeney, Jr. (ASN: 0-18080), United States Army Air Forces, for gallantry in action against the enemy while serving as Command Pilot of a B-29 Superfortress Bomber of the 73d Bombardment Wing, TWENTIETH Air Force, in aerial operations on 9 March 1945. Colonel Sweeney was participating in the greatest mass flight of B-29 aircraft ever dispatched against a single target. The historical very long range low altitude attack was a carefully planned and superbly executed incendiary mission launched from bases in the Mariana Islands against urban Tokyo. Three Hundred B-29 aircraft dropped the greatest load of bombs ever carried over such a vast distance. With exceptional precision and with devastating effect plane after plane released its bomb load with an efficiency, thoroughness and intrepidity that left transportation and communication facilities, plants and installations a mass of blazing wreckage. By this bold stroke the enemy suffered a crushing blow, resulting in the complete destruction of 15 square miles of Japan’s capitol city and the devastation of large industrial targets. Colonel Sweeney by his untiring efforts and initiative aided immeasurably in the careful and efficient preparation of this wing for its assigned task. His outstanding bravery and courageous leadership in the face of enemy opposition during this attack were a distinct contribution to the eminently successful conduct of this mission and will always be worthy of emulation.
