Reinhard Heydrich, then head of RSHA, sent Paulsen back to Kraków in order to seize additional museum collections, but Göring had already sent a team of his own men, commanded by SS-"Sturmbannführer" Kajetan Mühlmann under the supervision of Dagobert Frey, to loot the museums. Mühlmann agreed to let Paulsen take items of scholarly interest back to the Ahnenerbe, while keeping artworks for Göring. During the looting, however, Hans Frank, the head of the German General Government in occupied Poland, issued an order dated November 22, 1939 prohibiting the “unapproved export” of Polish items. Paulsen obeyed the order, but his colleague Hans Schleif arranged for five freightcars of loot from the Warsaw Archaeological Museum to be shipped to Poznań, which was outside Frank's control. In return, Schleif was appointed as a trustee for Wartheland. Paulsen later tried to take credit for the freightcars' contents in his report to RuSHA, but was reassigned.
