 Hitler then issued on 18 November his own directive, a "Führerbefehl" similar to the ones he had issued for Poland and Austria, announcing his prerogative over all confiscated art in the occupied Western territories.Rosenberg thus became a formal procurement agent for the "Führermuseum", except when Göring intervened.This apparently brought about some internecine squabbling, as Dr. Posse had been given the authority to act on Hitler's behalf, and the German commanders of occupied countries were required to keep him regularly informed about their confiscations of artwork.
