"For extraordinary heroism in operations against the enemy while serving as Pilot of a carrier-based Navy Torpedo Plane of Torpedo Squadron THREE (VT-3), embarked from the U.S.S. YORKTOWN (CV-5), during the "Air Battle of Midway," against enemy Japanese forces on 4 June 1942. Participating in a Torpedo Plane assault against Japanese naval units, Ensign Osmus, in the face of tremendous anti-aircraft fire and overwhelming fighter opposition, pressed home his attack to a point where it became relatively certain that, in order to accomplish his mission, he would probably sacrifice his life. Undeterred by the grave possibilities of such a hazardous offensive, he carried on, with extreme disregard for his own personal safety, until his squadron scored direct hits on two enemy aircraft carriers. His self sacrificing gallantry and fortitude were in keeping with the highest traditions of the United States Naval Service. He gallantly gave his life for his country."
