> This guy was a true hero.

Absolutely. Nor did he stop. Having left Auschwitz he volunteered to fight in the Warsaw uprising. He hid his rank so fought as a private but later took command of a unit. At war's end he tried to rebuild his network to seek evidence of Soviet atrocities in Poland. That eventually resulted in his capture, show trial and execution.

There are very few of his mould.
