Typically, when long-lost photos are found and restored they're a bit underwhelming. But this new series of images, captured by an unknown photographer, are just incredible โ€” from their portrayal of life in the trenches to the intimate glimpses of famous leaders.

All images: Collection Odette Carrez/Reuters. Above: German soldiers (rear) offering to surrender to French troops.

As Reuters reports, these new images are part of a collection of hundreds (yes, hundreds) of previously unpublished glass plates taken at the Western Front during the war. They were left behind by a viscount in the Armoured Cavalry Branch of the French Army.

French artillery officers:


They can be seen relaying instructions to adjust the cannon fire in a trench on the front line.

Moving artillery:


That's a 95 mm.

A seized German trench:


Anti-aircraft machine gun:

This French gunner was in a trench at Perthes les Hurlus in eastern France.

Inspecting trenches in the forest:


French officers inspecting trenches on the Argonne front in May 1916. Talk about impenetrable.

An unlikely beast of burden:

General Joseph Joffre:


Handing out medals to soldiers who fought in the Battle of Verdun, March 1916. Hardcore History podcaster Dan Carlin refers to him as the "Winston Churchill of World War I."

Field Marshal Horatio Herbert Kitchener:


He's the second from the left, meeting meeting French General Albert Baratier (R), on horseback, as French Marshal Joseph Joffre looks on (2nd R), on the Champagne front, Eastern France in 1915. Among other things, Kitchener is famous for his iconic moustachioed mug on British recruitment posters.

Time for a body cavity search:
