This is the first part of a planned four-volume series focusing on a hitherto largely neglected aspect of the Great War on the Western Front the war underground. The subject has fascinated visitors to the battlefields from the beginning of battlefield pilgrimages in the years immediately after the Armistice, and locations such as Hill 60 and the Grange Subway at Vimy have always been popular stops on such tours. Three other volumes will follow, covering the Somme, Ypres and French Flanders. Each book in the series has a short description of the formation and development of Tunnelling Companies in the BEF and a glossary of technical terms. This volume looks mainly at the central Artois, the environs of the whole line of the Vimy Ridge to the River Scarpe and Arras. It does not aim to be a complete treatment of the intensive mining operations along this front. It concentrates on mining, in the area of Vimy Ridge, in Arras itself and at the use of ancient underground quarries, taking Roeux as a good example. There are extensive descriptions of mining on and around Vimy Ridge, including photography and explanations of systems that have been accessed recently but are closed to the public, such as the Goodman Subway. The narrative draws on French and German archival material and personal descriptions. The text is illustrated with numerous diagrams and maps, in particular from the British and German records, and there is an exhaustive guide to the Grange Subway. Other sites opened to the public, in particular the Wellington Cave, are also explained and put into context. AUTHOR: Phillip Robinson is a retired Royal Engineers officer.
