Katy my dad was the same he died at 79 sorry I got his age wrong earlier.  He would never talk about the war, when he died he still had shrapnel in his back from were a mine went off behind him, he never told us what it was in his back it was one of my Uncles that let on.

My grandfathers were in the Irish guards in WW1 like yours they both died from lung problems. I am ex military myself so Remembrance day and ANZAC day are very special for me.
