It wasn't Carrie's War, that I do know, because in that they were evacuated to Wales. I know that story very well.
I think I remember the film Vicster means, but again, I can't remember what it was called, unless it was indeed 'The Leaving of Liverpool.
I remember the girl was placed in a British orphanage by her mother, who was going to come back for her. But she was told her mother had died and then they all got shipped off to Australia to become skivvies in the outback. There was one scene where they whipped out the kids' tonsils before they went.
The boys were sent to some sort of catholic-run home, and were abused by one of the priests, and then one of the boys drowned in a quarry whilst trying to run away.
Are we thinking the same thing here?
