From the M.I.S.-X Manual, circa 1944, I have posted the following sections that I thought would be of most interest. Click on the title to continue to that page.
Another source worth looking at is the book by John Nichol and Tony Rennell, Home Run, Escape from Nazi Europe, London: Penguin Books, 2008. See in particular the Appendix, Tips for Evaders and Escapers, Medical and Fieldcraft Hints (Issued by MI9 to escape and evasion lecturers, July 1944).
Also available on this website is the report, It’s the Little Things, Escape and Evasion During World War II.
