The Battle of Passchendaele took place between July and November 1917 and is widely regarded as one of the worst battles of both World Wars.
Fought by the Allies against the German Empire in a small corner of Belgium, it was a horrific event that ended with over 500,000 men killed, maimed, gassed or drowned - and many bodies were never found.
This book marks the centenary of the event. Historian Nick Lloyd references previously unexamined German documents to explain how the offensive put the Allies nearer to a major turning point in the war than anyone has ever imagined...
It's a fascinating and poignant read for anyone with an interest in military history, trench warfare or past wars.
