I never thought about it, they were the enemy, I never thought about it till years later.

And the reason I thought about it, I took the life probably 12 to 20 men somewhere, he's

a guy who never had a chance to reproduce children, and that bothered me.

These guys were denied that, and I've thought of it in that vein.

Still within touching distance in history, the long shadow of the Second World War,

the biggest and deadliest conflict the world has ever known, which drew in more than 30 countries

and killed around 80 million people. Still looms large over modern life, but for a precious few

scattered around the world, it lives on in their memories.

And then we went to Guam, and that's a day that I'll never forget.

William Gosh is one of them. We went down the ropes,

cannon board landing craft, and our ships all over the place. Battleships, cruisers,

destroyers, I know what all over the horizon, what an experience.

He's now 99, and stories like his from the battlefields in Japan and Guam,

a tiny island in the western Pacific could easily be lost forever.

But there's one person who spends day after day on a lonely mission to preserve every single one

of these accounts for the generations to come. By preserving a World War 2 veteran on camera,

I know that they're great, great, great, great grandchildren are not just going to get to know

their name, but they're also going to get to know the way they speak, the way they talk,

the way they laugh, the way they tell their stories, their characteristics.

The Imperial War Museum does that, and they have oral histories, and so do other museums and

institutions. But no one was doing it as systematically as Rishi was doing it as far as I can tell.

I mean, he was trying to get every single combat veteran.
