The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting a Bronze Oak Leaf Cluster in lieu of a Second Award of the Distinguished Service Cross to Captain (Air Service) Harvey Weir Cook, United States Army Air Service, for extraordinary heroism in action while serving with 94th Aero Squadron, 1st Pursuit Group, U.S. Army Air Service, A.E.F., near Crepion, France, 30 October 1918. Captain Cook attacked three enemy bi-place planes at an altitude of 1, 000 meters. After a few minutes of severe fighting his guns jammed, but after clearing the jam he returned to the attack, shot down one of his adversaries in flames, and forced the other two to retire to their own lines.
