They thought the yanks were babaric.
World War I, US forces deploy the Winchester Model 1897 short barrel, pump action shotgun, or M97 Trench Gun, to devestating effect — each round of buckshot ammunition contained nine 00 (.33-caliber) pellets. So devestating in fact, that Imperial Germany formally protests the US’s use of this barbaric weapon. From a period political cartoon, Uncle Sam laughs off the Kaiser’s protest, pointing out the extensive list of barbaric actions taken by Germany.
