Here is another excerpt from the interview the Joong Ang Ilbo conducted with South Korean military hero Paik Sun-yup:

The battle went on this way for quite some time but in the end the tanks prevailed.

When they returned, they created quite a stir within the whole unit. Seeing two tanks completely soaked in blood was more than enough for the rumor mill. According to General Kim’s memoir, a strange thing happened when the tanks returned. Upon arriving at the base, a tank gunner jumped from the blood-soaked tank and started running, making incomprehensible sounds as he went. The tank platoon commander went off in pursuit of the soldier to calm him down and finally had to tackle him to stop him from running around like a crazy man. Needless to say, the soldier had lost his mind amid the carnage as the fear he felt became relentless.

So started the Battle of Unsan: Two blood-soaked tanks and a G.I. gone mad. But that was only the beginning.  [Joong Ang Ilbo]
