I once posted a photo of my grandfather as a young man of 18 or so here on the old CP. Actually since that's toast now, here it is again:
This was my Mum's dad. He died before I was born. When this photo was taken, he was in the Royal Horse Artillery. He was given the dress uniform pictured to take part in a recruitment tour. This involved a lot of charging around parks on horseback to encourage the lads who came to watch to join up.
He met my grandmother only months before going to India, and didn't see her again until he came back in 1926. They were married shortly afterwards. He was very disappointed to have missed out on the Great War. It was all done and dusted by the time he was old enough to go and fight.
I don't know if he met my other grandfather - I suppose he must have done. If he could have spoken to him about his time in the war, he wouldn't be sorry he'd missed out.
And here he is thirty-five years later, in 1953:
.. that's my older brother and one of my cousins in the back.
