For extraordinary heroism and distinguished service as pilot of an airplane of Scouting Squadron Five in action against enemy Japanese forces in the Battle of Midway during the period June 4-6, 1942. Defying extreme danger from concentrated anti-aircraft fire and fierce fighter opposition, Lieutenant Horenburger, with utter disregard for his own personal safety, participated in persistent and vigorous attacks against the Japanese invasion fleet. His gallant intrepidity and loyal devotion to the accomplishment of a vastly important objective contributed in large measure to the success achieved by our forces and were in keeping with the highest traditions of the United States Naval Service.
