Dum-dum Bullets used Against the Russians
That the Germans used dum-dum bullets against the Russians was proved in a hospital at Vilna, where a lieutenant-colonel in the Russian infantry, wounded in the leg, chanced to be under treatment. The wound, which at its entrance was smaller than a penny, was as large as a hand where the bullet left the body.
The photograph of one of the dum-dum bullets used in this way was given by the Novoïé Vrémia on 17th September, 1914.
Moreover, the German missiles used against the Russian troops often gave off poisonous gases which caused the death of the wounded, and which were expressly forbidden by the Hague Conventions (1899) under the category of “projectiles, the sole purpose of which is to spread asphyxiating or noxious gases.”
