Secret memo from Heinrich Himmler to Adolf Hitler.
In the treatment of the alien populations of the East we shall have to endeavor to recognize and nurture as many individual peoples as possible; that is, in addition to the Poles and Jews also the Ukrainians, the Byelorussians, the Gorals (Goralen), Lemcos (Lemken), and the Cashubes (Kaschuben). And if there are any other splinter peoples to be found anywhere, then these too.
I wish to say by this that we have the greatest interest in not uniting the population of the East, but, on the contrary, in dividing it into as many parts and splinters as possible.

Whatever is said concerning these splinter peoples applies on a correspondingly larger scale to the Poles.
