Can you identify this book from my two vague recollections?

[Yeni]

I've decided to read all the set books I didn't read in my first year of secondary school. I was a complete slacker at school and did the bare minimum and now I'm making up for lost time almost 30 years after the event.

So...the book I am looking for is set in or around WWII and the plot involved three, or possibly two, children trying to get to Lake Constance. That's all I can remember!

Any ideas? It took me months to figure out the title of A Traveller In Time, and at least I could remember some of the characters in that. I won't be able to work this one out without help.

Quick Google came up with the Silver Sword?

It could be The Silver Sword by Iain Serrailler? Were they Polish children?

if it silver sword then it's been read on radio 4 extra at the moment

Def The Silver Sword

I loved The Silver Sword. It is supposed to be based on a true story.

Wow, that was quick! Thank you! That's it. Great about it being on R4 extra, or R7 as I insist on calling it. I've recorded loads of great things onto DVD and I was actually going to ask on MN how to put them onto CD as I find the concept of watching the radio a bit odd, and I don't have a digital radio.

You can rely on MN for a prompt answer.
