The President of the United States of America takes pride in presenting the Navy Cross (Posthumously) to First Lieutenant Robert E. Stevenson (MCSN: 0-11643), United States Marine Corps Reserve, for extraordinary heroism as Commanding Officer of Company A, Fourth Tank Battalion, FOURTH Marine Division, in action against enemy Japanese forces at Saipan, Mariana Islands, on 20 June and 4 July 1944. Learning that two attempts to close a 400-yard gap between two infantry battalions had failed, First Lieutenant Stevenson immediately reported to the area and volunteered his services. Fully realizing the danger to his tanks, he unhesitatingly pressed forward and, penetrating the entire distance under heavy artillery and mortar fire, steadfastly maintained his position for a period of two hours, drawing all enemy fire to the area and enabling the battalions to establish contact free of Japanese resistance. Again volunteering to enter a large draw where the intensity of hostile fire had prevented a reconnaissance, he gallantly advanced and, when three of his tanks were rendered inoperative by enemy action, maneuvered so skillfully as to effect evacuation without a single casualty. By his brilliant leadership, his indomitable fighting spirit and cool courage in the face of grave peril, First Lieutenant Stevenson contributed materially to the success of these and other hazardous operations in this vital war area, and his valiant devotion to duty throughout this period was in keeping with the highest traditions of the United States Naval Service.
