 As such, to prove his thesis Goldhagen focused on the behavior of ordinary Germans who killed Jews, especially the behavior of the men of Order Police Reserve Battalion 101 in Poland in 1942 to argue ordinary Germans possessed by "eliminationist antisemitism" chose to willingly murder Jews.The 450 or so men of Battalion 101 were mostly middle-aged, working-class men from Hamburg who showed little interest in National Socialism and who had no special training to prepare them for genocide.Despite their very different interpretations of Battalion 101, both Browning and Goldhagen have argued that the men of the unit were a cross-sample of ordinary Germans.
