Verdun 1916: The Deadliest Battle of the First World War (Paperback)

Fought on the heights above the garrison town of the same name on the River Meuse, 140 miles east of Paris, the Battle of Verdun lasted for ten months, between February and December 1916, double the length of the Battle of the Somme and over three times the length of the Battle of Passchendaele. Conceived by the Germans as a means of destroying the French army through attrition rather than breakthrough and encirclement, the battle cost 300,000 lives.

Massed artillery was employed on a hitherto unprecedented scale; the initial bombardment lasted for nine hours and saw 80,000 shells fall on the French trench line, while on the ground the initial attack saw the combat debut of storm-troop tactics and the man-pack flamethrower. As the battle raged the combatants endured heat and thirst akin to desert conditions together with bottomless mud as bad as at Passchendaele. In addition, fixed defences like the forts of Douaumont and Vaux sparked hellish underground fighting in subterranean pitch darkness that occurred nowhere else on the Western Front.

The result was almost 200 square kilometres of ground that had been blasted, ploughed and poisoned into a wasteland by explosives and gas, so much so that the post-war French authorities were unable to return it to its former agricultural use and simply left it to the elements.
