Pressed post too early! Anyway, the children picked up shrapnel off the beach and sent it home with a message saying, "It's just as dangerous here as at home, please let us come home," which was of course not true, and were allowed home.
Gran was then in London during the worst of the Blitz. She remembers coming home from school and finding her mum's slippers in the middle of the road where she'd left them in her hurry to get to the air raid shelter with the younger sister, and not knowing if that meant her mum had been killed by a bomb (she hadn't been).
Her brother's best friend was killed, but she never talked about that much, and they were bombed out at one point.
When my mum was a child, 20 years later, gran had what I can only describe as a PTSD attack when an aircraft came over and for some reason cut its engine overhead. (When you heard the engine of a Doodlebug cut out, that's when the danger was - it was about to land.) Something I think is interesting though is that she's never, ever expressed regret that they came back from Cornwall. Even though they were well treated there, and London was clearly traumatic, they preferred London and being with their family (her dad wasn't called up, as too old - he'd fought in WW1.)
