This year marks the 100th anniversary of the start of the Great War.
Rare black and white images have captured life on the trenches during World War One.
A Viscount in the Armoured Cavalry Branch of the French Army left behind a collection of hundreds of glass plates taken during WWI that have never before been published.
The images, by an unknown photographer, shines a light on the daily lives of soldiers in the trenches.
