Although no one in my family fought in the Second World War, my great grandfather was in the Canadian Army during the First World War.
He was a messanger, and unfortunately he got gassed up pretty badly. I don’t remember how long he was in the war, but I do remember records saying that he fought in the battle of Passendale. He later got brought back to Canada after he got shot in the leg  :-(
My grandmother tells me that he never talked about the war; he never even kept any part of his uniform. But at least my grandmother kept his medals and she still has a photo of him in his military uniform :-D
I wished I had asked more questions to my relatives.
I believe one serviced Halifaxs in India though on reflection
I was unaware whether they were based there, others served
in the Merchant navy or in the Fire service etc.
One account I recently read about the gassing in WW1 was
a doctor treating two patients, the Chlorine gas was so strong
on them that he left the room to be sick.
