“How can I forget?”

A Brynaman veteran of the Korean War is to feature in a revealing S4C documentary recalling the conflict which ended in 1953.

More than 65 years on from the armistice, Meirion Davies, now 83, shared his recollections of the war in Dagrau o Waed: Rhyfel Corea, which is due to be broadcast on Thursday, 25 June.

The programme also features Young-Bok Yoo, who spent 50 years as a prisoner of war in North Korea.

The horrors they witnessed still affect them both and Mr Davies still suffers nightmares from what he saw.

"Bitter reminders about the war still hit me today and you can't do anything about it,” said Mr Davies.

“My wife used to say, 'forget about it'! And I always told her, how can I forget about it?"

In 1950, North Korea - led by the communist authorities - attacked their democratic neighbours, South Korea.

The war lasted three years and had long-lasting effects: four million soldiers died, and millions more were injured and tortured.

Thousands of British soldiers went to fight, including Mr Davies, and in the documentary he speaks openly about his soldier past and shares stories from the battlefield.

Since then, North Korea has proved a mystery to the rest of the world.

Young-Bok Yoo spent 50 years as a prisoner of war in North Korea, until he escaped aged 71 to South Korea.

Now, aged 84, Mr Yoo speaks candidly about the atrocities he witnessed and risking his life to escape.

The war tore his family apart; his father and sister lived in South Korea, and his mother and other siblings lived in North Korea.

He talks emotionally about seeing his mother and sisters sleeping in a hole in the ground.

After escaping from North Korea, he was separated yet again from his family.

"The North Korean government never treated me like a human being,” he said.

The programme is part of a co-production between S4C, JTV channel in South Korea and produced by Welsh production company Awen Media.
