On the morning of 11 July 1950 the enemy advanced to within 25 yards of the command post of Company K. with several platoons running out of ammunition, Master Sergeant Dunn under heavy enemy fire organized and directed an ammunition detail. During the attack the enemy set up a machine gun in a forward position. Master Sergeant Dunn crept forward and succeeded in knocking out the machine gun. At this time an order to withdraw was issued and Master Sergeant without regard for his own safety, collected men and withdrew them with a minimum of casualties. During the withdrawal the enemy set up another machine fun which brought fire on Master Sergeant Dunn and his group. He again crept forward and succeeded in knocking out this machine gun.
