as promised, pictures between 1900-1940 ( most around 1920) of soldiers of the Sultan but also tribesmen from the North and South who were battling the Sultan's forces as well as the French ( "tiens, voilą du boudin..." ) and Spanish who all didn't always enjoy their stay at the territory of these men ( Morocco as we know it now with its present borders, is a very young ...) and meeting these gents uninvited was no pleasure at all to say the least. The Romans already found that out very quickly...
Especially the Riffians were severe opponents not to mess with ; over 20 tribes of which the Aith Waryagher (Aith Ouariaghel) from the Nort-East Morocco and North-West Algeria were very fierce fighters. Supposedly their name means "those who do not retreat "
