Kerry Smith recalls visiting the grave of his friend in Korea when the war ended and again 40 years later.
"I looked at his grave, it had a cross, that they had there, it was just a sort of a wooden cross with his name on it and that sort of thing, serial number. And I couldn't, I didn't have the guts to talk to him then.
When we went back in '93 we walked around the graves, lot of the fellows that we knew who had been killed, I mean a lot of blokes lost a lot of mates. And I went and had a look at his grave, the headstone. I placed a card there... on which I had written to him asking his forgiveness for not going to his funeral...I'll have to have a drink of water I think...
I knew he could read it but I printed it so he could read it because my writing is shocking, but I told him too. So we had a bit of a talk. He said, 'How are you going Smithy?' He said, 'Don't worry about it mate'."
