Was thinking about my grandparents last night and how they were involved in the wars. they all did very different things
My grandfather was an older father to my dad (IYSWIM) and fought in the trenches in World War one. He was exposed to mustard gas and left with life long breathing difficulties but was involved with Air Raid Precaution during the World War 2.
My father's mum was a nurse at one of the big military hospitals and also a volunteer for the WRVS.
Both of my mother's parents were farmers so were in reserved (and necessary) occupations. They had Italian and German prisoners of war working on the farm as well as the Land Girls and my Nana had to learn Italian and sometimes did translation for the military - not bad for a girl who left a very rural Irish school at the age of 12 and worked on teh land ever after
I don;t really know about DP's grandparents but I do know his great uncle was a code breaker at Betchley Park (DP would probably have ended up in the same place I think)
