I have a copy of Ruckmarsch then and now , superb one of the finest photo ATB's i've seen although i must also recommend Heimdals Le Couloir de la Mort by Georges Bernage which i picked up in Normandy this year , it's all in French but the photo captions are understandable even with my poor french , great maps and photos of St Lambert sur Dives, Moissy , Chambois and Montormel and of course the Vimoutiers Tiger,
