On March 26th 1942, the Führer received Lieutenant-General Hube, Colonel Traut, two majors, and Lieutenant Ströhlow for the delivery of the Oak Leaves.

On this occasion, the Führer gave a speech about the reconstruction of the East and said verbatim:

"I know how far I have to go, but in return the entire East will become Germanic, PROTO-GERMANIC." This message is from a primary source and is reliable. (And in a very affectionate tone): "For now, we don't need to think about it, and I won't talk about it. I have entrusted this to my Himmler, and he will take care of it."

— Gottlob Berger
