As Christopher Nolan's film Dunkirk celebrates one of history's most successful rescue operations, never-before-seen images document the fate of more than 80,000 Allied troops who failed to escape Dunkirk.
Described as the forgotten heroes, these images give a haunting glimpse into the torture that awaited the Prisoners of War captured during the Dunkirk evacuation.
Matthew Smaldon (@wwiistories) shares photographs taken by German soldiers to reveal the reality of the horrors the captured men went through.

An unknown British soldier was buried under a tree with a burnt out lorry in the background. The grave has been adorned with flowers, presumably by French civilians.

While the reviews of Christopher Nolan's Dunkirk have been overwhelmingly positive, some criticism has been leveled at the lack of French troops in the movie.
Many of the troops fighting in French uniform were from the French colonies, including Senegal, Mauritania and Niger.
German troops, as pictured above, often took photographs of these men when captured, as colonial troops were seen as a novelty to the Germans.
Over 100,000 French colonial soldiers were held captive during the war.
Despite the smiling faces in this picture, tragically some POWs were killed by their captors close to the battlefield.

In the distance you can see ships sunk during the evacuation and a row of lorries used as a temporary bridge to help soldiers reach ships in deeper water.
German soldiers inspect abandoned vehicles somewhere near Dunkirk.
Whether these had been brought to this location after being removed from roads and ditches is unclear.
But the sheer number of vehicles gives an indication of the material left behind.

The Germans had been clearing the beach of material and ammunition boxes have been neatly lined up.
Note the four Vickers machine guns which have been recovered.
