Citation... Sgt. Libby distinguished himself by conspicuous gallantry and intrepidity above and beyond the call of duty in action. While breaking through an enemy encirclement, the vehicle in which he was riding approached an enemy roadblock and encountered devastating fire which disabled the truck, killing or wounding all the passengers except Sgt. Libby. Taking cover in a ditch Sgt. Libby engaged the enemy and despite the heavy fire crossed the road twice to administer aid to his wounded comrades. He then hailed a passing M-5 artillery tractor and helped the wounded aboard.
