there were many major trials against the nazis: the imt (nuremberg trials) and the subsequent trials against ig farben and oswald pohl  the bergen belsen trials the frankfurt auschwitz trials the eichmann trial i cant tell you how many nazis confessed probably almost all of them as actually arguing the defence that they didnt commit their crimes was holocaust denial and therefore illegal, as well as being judged as perjury since the facts of the holocaust were and are viewed as ipso facto true. there were a few high ranking nazis who denied the holocaust including: hans aumeier josef kramer thies christopherson wilhelm staglich etc
