Conspirators in the Polish Blue Police and Polish Criminal Police in Kraków during 1939-1945

The article describes the history of Polish pre-war policemen who were forced to continue their service in the Polish Police in the General Government (the so-called Blue Police), created by German occupying authorities. Many of these policemen, faithful to the oath they had made before the war, worked for the Polish Underground State. In Kraków, the capital of the General Government, in the Autumn of 1939, Polish policemen began to create conspiracy structures, which gradually became one of the most effective Polish intelligence networks. Thanks to them, the Home Army, subordinated to the Polish Government-in-exile in London, could learn the secrets of the Kraków Gestapo and the German police. Despite the enormous efforts of the German counter-intelligence machine and the losses among the conspirators, they worked out the exact structure of the German forces in Kraków, helped the persecuted population and infiltrated secret German institutions. In post-war Poland, many of them experienced persecution at the hands of the communist regime. Most of them preferred to keep their wartime experiences secret. To this day their activities are poorly known, being suppressed by the popular image of a Polish policeman-collaborator created by the media.
