Interesting action of polish Home Army during WW2.
Polish officer ,Jan poznański,who fought in France and later was trained and parachuted to Poland,made big mistake - he made friend with one neighbour,and told him that he is in Home Army and come from England.
His friend was gestapo agent.He get arrested,tortured - but,germans,instead of kill him after getting info,tried to made him their agent .he agree to found higher ups in polish underground, get free,go to his superiors,and,when he meet with two gestapo agents in coffe shop "European" - Boehme or Boehm and sidekick,probably Dolężal.
Both was schoot by waiting poles.
Poznański was send to another city,never screw up,and died during killing gestapo agent Helena Michalkowa 22.10.1943.
Interesting story - both sides made stupid mistakes,but this time we win.
