The President of the United States of America takes pleasure in presenting the Silver Star to Lieutenant Colonel Royal Bertram Allison (ASN: 0-437462), United States Army Air Forces, for gallantry in action while serving as Pilot of a B-25 Bomber in the 310th Bombardment Group (Medium), TWELFTH Air Force, while leading a thirty-plane formation in an attack upon a railroad bridge at Ora, Italy, on 10 March 1945. Upon the commencement of the bomb run, direct hits and shell fragments from an intense and accurate anti-aircraft fire destroyed four B-25s and damaged 18 others. Displaying great courage and determined leadership in the face of this strong resistance, Lieutenant Colonel Allison maintained his plane in lead position and guided the bombers on a perfect run over the objective. With all bombardiers releasing in perfect coordination with the lead bomber, a concentrated pattern of bombs in the target area heavily damaged a bridge thereby blocking a vital link in enemy communication lines. Lieutenant Colonel Allison's gallant devotion to duty and outstanding proficiency in combat reflect highest credit upon himself and the Armed Forces of the United States.
