The President of the United States of America, in the name of Congress, takes pride in presenting the Medal of Honor (Posthumously) to Private First Class Robert Lee Wilson, United States Marine Corps, for conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while serving with the Second Battalion, Sixth Marines, SECOND Marine Division, during action against enemy Japanese forces at Tinian Island, Marianas Group, on 4 August 1944. As one of a group of Marines advancing through heavy underbrush to neutralize isolated points of resistance, Private First Class Wilson daringly preceded his companions toward a pile of rocks where Japanese troops were supposed to be hiding. Fully aware of the danger involved, he was moving forward while the remainder of the squad, armed with automatic rifles, closed together in the rear when an enemy grenade landed in the midst of the group. Quick to act, Private First Class Wilson cried a warning to the men and unhesitatingly threw himself on the grenade, heroically sacrificing his own life that the others might live and fulfill their mission. His exceptional valor, his courageous loyalty and unwavering devotion to duty in the face of grave peril reflect the highest credit upon Private First Class Wilson and the United States Naval Service. He gallantly gave his life for his country.
