Trench Raiders series takes place on the Western Front. There were other fronts, however, including those in the Alps, Eastern Europe, Turkey, the Near East, and Africa.
This shot shows a German trench in Cameroon sometime between 1914 and 1916. The Germans had a number of colonies in Africa and their colonial forces fought the colonial forces of Belgium, France, and Britain. The majority of soldiers were local recruits fighting in colonial regiments. Civilians, too paid the price.
In a fascinating article on the BBC about the East Africa Campaign, the author tells how more than one million died just in that one region of the continent. No one is clear just how many died in Africa as a whole since the colonial rulers didn't bother counting.
