After the war he lived four years in the same small village as my grandmom, breeding chicken and working in the woods until he saved enough money for his escape to Argentina. He supposedly even sold his eggs to the Jewish survivor community of the closeby concentration camp Bergen-Belsen.
For anyone who hasn't seen it, the 2018 movie "Operation Finale" with Oscar Isaac and Melanie Laurent shows how Eichmann was found and captured by Mossad agents in South America. I don't know how accurate the movie is but these are great actors and I really enjoyed the movie.
