Part of the book includes account of Foyster's time in a Prisoner of War Camp in Göttingen.

His wound was slow in healing, and this fact finally led to his transfer to neutral Switzerland where he was interned at the holiday resort of Mürren. This account is probably one of the few published accounts which gives details of Internment in Switzerland.
