I got the link to that via Herb's retweet from @SarahJSchles link ... which led me to the following:
That man is not an actor. That is Jack Jennings, Private, British Army. A short interview.
Jack served with the Suffolk Regiment, the First Battalion of the Cambridgeshire Regiment, and was fighting a fierce last stand in Singapore when it eventually fell to the Japanese in February 1942.Read it all, here.
Jack explains: “After the surrender had been signed we had to just wait for the Japanese to come and collect us. 500 of us were rounded up and taken to sit in a tennis court at the back of a large house. We had to sit there for five days, in the full sun, with water only occasionally and just biscuits thrown over the fences for food.
“We were then moved and put into Changi prisoner of war camp – worn out, tired and starving. The camp was packed by the time our company had arrived, so we had to settle for anything. After a meal of rice and watery soup, we felt better.
