This is a real situation from September 1939. It shows a beginning of an attack. They jumped over the edge of their trench, and one of the soldiers had been hit.  

Attack of the Polish infantry Sept. 1939

Not great quality - but a nice snapshot of Wojtek, the famous Polish soldier bear, with an unidentified Polish artilleryman, that I just happened across.  As Wojtek was little more than a big cub here, this was presumably taken in Syria, or in the Poles' early days in North Africa.  Best regards, JR.
