North Koreans had also approached Yongsan from the south . The US 2nd Division Reconnaissance Company and tanks of the 72nd Tank Battalion opposed them in a sharp fight . In this action , Sergeant First Class Charles W. Turner of the Reconnaissance Company particularly distinguished himself . He mounted a tank , operated its exposed turret machine gun , and directed tank fire which reportedly destroyed seven North Korean machine guns . Turner and this tank came under heavy North Korean fire which shot away the tank 's periscope and antennae and scored more than 50 hits on it . Turner , although wounded , remained on the tank until he was killed . That night North Korean soldiers crossed the low ground around Yongsan and entered the town from the south .
