Career
Flisykowski was captured by the Germans on 2 September 1939 and handed over to the Gestapo. Denied the legitimate status of Prisoner Of War, he was put on trial (which was later found to be illegal), together with the other 37 captured post-office workers. Designated as a "bandit" by a paramilitary court (and therefore not protected by the Geneva Convention), he was sentenced to death and executed by firing squad in Danzig-Saspe on October 5, 1939.
Flisykowski"s grave was discovered in 1991.
In the same year the families of the killed postmen founded an association called Circle of the Families of the Former Workers of Gdańsk Post Office (Koło Rodzin Byłych Pracowników Poczty Gdańskiej) with a goal to repeal the verdict qualifying the postmen as bandits. With the help of Dieter Schenk, a former worker of Interpol and the author of a book on the subject, the case was put into a verification trial.
As a result of these actions the Land Court in Lübeck made a decision, on 30 December 1996, that the previous verdict of 1939 sentencing Flisykowski to death was illegal. He was awarded the posthumously on 1 September 1990.
