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. The enemy directed intense small-arms fire at the driver, and Sgt. Libby, realizing that no one else could operate the vehicle, placed himself between the driver and the enemy thereby shielding him while he returned the fire. During this action he received several wounds in the arms and body. Continuing through the town, the tractor made frequent stops and Sgt. Libby helped more wounded aboard. Refusing first aid, he continued to shield the driver and return the fire of the enemy when another roadblock was encountered. Sgt. Libby received additional wounds but held his position until he lost consciousness. Sgt. Libby's sustained, heroic actions enabled his comrades to reach friendly lines. His dauntless courage and gallant self-sacrifice reflect the highest credit upon himself and uphold the esteemed traditions of the U.S. Army.
