They probably didn't. BTw, none of the documents so far contain the "evil man in Potsdam/Berlin" quote, either, nor for Fritz the "three whores of Europe/must smell of diapers/birthing machine quotes. Though they do have the "bigotted maenad" I was already familiar with, as well as "It's easier to fight brave men than a malicious woman". (When MT post Leuthen doesn't offer peace.)
