He then spent three years in Prisoner of War camps in Italy (Chieti), Germany (Moosberg, Brunswick) and Czechoslovakia (Marisch Trubeau Oflag VIII-F). While imprisoned, Murray wrote a book entitled Mountaineering in Scotland. The first draft of the work was written on the only paper available to him ? rough toilet paper. The manuscript was found and destroyed by the Gestapo. To the incredulity of his fellow prisoners, Murray's response to the loss was to start again, despite the risk of its loss and that his physical condition was so poor from the near starvation diet that he believed he would never climb again. The rewritten work was finally published in 1947 and was followed by the sequel, Undiscovered Scotland, in 1951. Both concentrate on Scottish winter climbing and were widely credited with helping to inspire the post-war renaissance in the sport.
