'They would jump in the trenches and blow themselves up'

Ken Keld is sitting in the lounge of his immaculate one-bed bungalow outside Scarborough, North Yorkshire.

Aged 91, he is a gentle and softly spoken Yorkshireman who still walks a mile a day. Given his warmth, it is hard to place him into the events he is describing.

'The shelling seemed to stop dead, you could have heard a pin drop. Within seconds they're there on top of us, we're outnumbered five to one,' he says.

'They were fanatics, they'd jump in the trenches and blow themselves up. It was hand-to-hand combat, it was practically every man for himself'.

The great grandfather-of-two is a veteran of the Korean War, a conflict which, over the course of three years, claimed the lives of 1,100 British soldiers - more than in the Falklands, Afghanistan and Iraq wars combined.
