In yet a further irony of history, we find:

Hitler also had a penchant for the Saxon novelist Karl May’s Wild West adventure stories, which he had reissued in a special field edition for German soldiers at the front and later recommended to his military commanders as manuals of strategy. (Don’t blame the innocent May, whose entertaining tales of the wise Apache Chief Winnetou and his “white blood brother” Old Shatterhand were also a favorite of Albert Einstein.)
