Aerial photography was a relatively new technology at the onset of World War I & was embraced as an indispensable tool of wartime intelligence by all nations involved in the conflict. As a result, thousands of photographs taken from the air over the battlefields of the Great War have survived in archives throughout Europe, Australia & the United States. These pictures present the war from a unique perspective, clearly showing the developing trench system, artillery batteries, bunkers, railway lines, airfields, medical evacuation routes & more. They reveal the expanding war in Flanders Fields as the hostilities spread, kilometre by kilometre, devastating the environment & resulting in the complete destruction of the landscape at the front. This illuminating volume, the results of a collaboration between the In Flanders Fields Museum, Ypres, the Imperial War Museum, London, & the Royal Army Museum, Brussels, features hundreds of photographic case studies, illustrating in unprecedented detail the physical extent of World War I & the shocking environmental damage it left in its wake. Supplementing aerial images with maps, documents & photographs taken from the ground, this one-of-a-kind visual record stands as an important contribution to World War I history, revealing the wartime landscape of Flanders Fields as rarely seen before.
