Yes, that was Jacqueline Le Pelley who broke her ankle. Perhaps she was on holiday in Tyrol, though why you would take a child with a broken ankle to a remote TB sanatorium (unless she fell while actually mountain climbing at the Sonnalpe) remains a mystery. 
I'm still reading Goes To It, which occupies some weirdly double positions on certain things. Obviously, that someone is showing lights during blackout in the school grounds is a serious one, yet the Colonel who shows up to investigate is viewed as a buffoon, and Joey, who can do no wrong, is allowed by EBD to mock him openly by swanning in late and answering for the behaviour of the baby triplets in front of the whole school?
And Gwensi, Daisy and Beth, when they catch the poachers who turn out to be the ones using lights, say they won't turn them in if they join up??? Despite the fact that the rest of the novel is about the suffering of war, and Jack being missing...?
And the snobbery about the evacuee children, who, understandably, have never been around farm animals or around wildflowers you're allowed to pick, annoys me every time I read it, especially when it's CS girls who have been leaving gates open so livestock gets out....
