"The product of over twenty-five years of research, Beneath Flanders Fields illustrates the evolution of military mining, leading to its deployment in the greatest siege in military history - in the trenches of the Western Front." "In the words of the tunnellers themselves, and through previously unpublished photographs - many in colour - as well as contemporary plans and drawings, this book reveals how this most intense of battles was fought - and won. Few on the surface knew the horrific details of the tunnellers' work, yet this silent, claustrophobic conflict was a barbaric struggle that raged day and night for almost two and a half years, and one which generated mental and physical stresses often far beyond those suffered by the infantry in the trenches. On 7 June 1917 at Messines Ridge, the tension was broken with the opening of the most dramatic mine offensive in history."--BOOK JACKET.

Simon Joness graphic history of underground warfare during the Great War uses personal reminiscences to convey the danger and suspense of this unconventional form of conflict. He describes how the underground soldiers of the opposing armies engaged in a ruthless fight for supremacy, covers the tunneling methods they employed, and shows the increasingly lethal tactics they developed during the war in which military mining reached its apotheosis. He concentrates on the struggle for ascendancy by the British tunneling companies on the Western Front.But his wide-ranging study also tells the story of the little known but fascinating subterranean battles fought in the French sectors of the Western Front and between the Austrians and the Italians in the Alps which have never been described before in English. Vivid personal testimony is combined with a lucid account of the technical challenges and ever-present perils of tunneling in order to give an all-round insight into the extraordinary experience of this underground war.
