In outline this comprehensive book describes the German structures employed to defend the territory captured around Ypres and makes excellent use of official drawings and maps as well as photographs from the authors' collections.
The many photographs are fascinating. As acknowledged experts - and with Nigel Cave's editing involvement and a decent translation from the original - the author leaves little to say about the subject and have delivered a readable book.

Stand To! Journal of the Western Front Association

Overall this work provides the reader, whether military history buff or not, with a clear insight into just how ‘tough a nut’ the German line was for the Allies to crack in 1918. Its place on our library shelves is well deserved.

RUSI Victoria

The book is complimented by fantastic photographs, diagrams and support text detailing the various aspect of these constructions.  Many of these have not been seen in Britain before.   A tremendous resource for anyone interested in the Western Front, and also a complementary on the ground book to use if you are visiting the area.

The English-language edition has added to their work to include a tours section that takes the visitor to accessible remaining structures in the Salient area, with a glossary of German terms and their English equivalents... There is extensive illustration of the highest quality.

This is something outside of the norm and well recommended.

Highly recommended. 10/10
