For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while serving with the 2d Battalion, 6th Marines, 2d Marine Division, during action against enemy Japanese forces at Tinian Island, Marianas Group, on 4 August 1944. As 1 of a group of marines advancing through heavy underbrush to neutralize isolated points of resistance, Pfc. 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.
