4 June 2021 - I finished this interesting read off this afternoon.
It tells the true story of two English soldiers, Fred Foster and Anthony Coulthard, who escaped from Stalag XXA in Nazi-occupied Poland. Their achievement was more remarkable as they didn't take the most direct route home, instead they travelled by train into Berlin, and all the way across Third Reich Germany to the Swiss border.
