A little over two months after the invasion , '' SS-Obersturmbannführer '' Bruno Müller , the newly appointed chief of the Gestapo in Kraków , called a meeting of all university professors and academics at the Collegium Novum . He informed them that the Poles did not have permission from the German authorities to start a new school year . They were arrested on the spot , as part of an integrated action plan known as '' Sonderaktion Krakau '' . Klimecki was apprehended at his home at 5 pm the same evening . Within days , they were deported in one rail car – 184 persons in all – to Reichsgau Wartheland and soon imprisoned at Sachsenhausen concentration camp near Berlin . Klimecki spent over three months there during the winter
