The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pride in presenting the Distinguished Service Cross (Posthumously) to Technician Fourth Grade Oliver L. Yambert (ASN: 6931736), United States Army, for extraordinary heroism in connection with military operations against an armed enemy while serving with Company G, 2d Battalion, 129th Infantry Regiment, 37th Infantry Division, in action against enemy forces at Manila, Luzon, Philippine Islands, on 9 February 1945. Technician Fourth Grade Yambert was a member of an assault platoon which captured a concrete power plant building on Provisor Island, a small plot of land covered with buildings and completely surrounded by estuaries of the Pasig River. After fighting for four hours against a numerically superior enemy, they were driven from the building and dug in behind a coal pile near its entrance. The enemy, supported by fire from atop the structure, then attempted to outflank the group on both sides, and offered a serious threat to the assault troops. Every man in the group had been wounded or killed. Technician Fourth Grade Yambert volunteered to attempt to carry information of his comrades; plight to his company command post by swimming across the fifty yard estuary, which was covered by grazing fire from enemy automatic weapons. While swimming, he was hit and killed by fire from an enemy machine gun. His heroic action in giving his own life for his comrades in arms exemplifies the highest traditions of the military forces of the United States and reflects great credit upon himself, the 37th Infantry Division, and the United States Army.
