Jacques Trolley de Prévaux

'En Dirigeable sur les champs de bataille' is a 78-minute film recently discovered in the archives of the French army in Paris. The pilot was Jacques Trolley de Prévaux. His cameraman was Lucien Lesaint. In August and September 1919 they filmed the remains of the Western front, from Nieuwpoort, on the North Sea in Belgium, to the Swiss Alps.

The story of the Great War told from a unique new aerial perspective. Featuring two remarkable historical finds, including a piece of archive footage filmed from an airship in summer 1919, capturing the trenches and battlefields in a way that has rarely been seen before. It also features aerial photographs taken by First World War pilots - developed for the first time in over ninety years - that show not only the devastation inflicted during the fighting, but also quirks and human stories visible only from above.
