It is awful to think all those poor people were killed for such an unnecessary war, which led directly to WW2, which we did have to fight.
I have put up a framed photo of my paternal grandfather who fought in WW1. He is wearing his uniform and it was taken just before he was sent across the channel. He was gassed and was never 100% again. He died in 1943 at the age of 48!
That's very sad floo. I had an uncle (who was old enough to be my grandfather), who was gassed. He was lucky I suppose, certainly compared to your grandfather, he lived to his early seventies, brought up three children. His chest was never very good, which one would expect, and he was quite 'nervy', ie would be easily startled. Nice man, he died when I was 18.
WWl was terrible and, as you said, unnecessary. What a waste of life - and such extreme patriotism! When you think how Rudyard Kipling connived so that his son, Jack, was able to join up, even though his eyesight was terrible, it beggars belief. Kipling regretted that of course when the boy was killed in action. People had no idea how difficult it would be, thought it would be all over in no time.
