Augustyn Träger (25 August 1896 – 22 April 1957), codenames Sęk (Knot) and Tragarz (Porter), was a Polish-Austrian soldier during World War I and an intelligence officer in interwar and German-occupied Poland.
[1] Initially, right after the Nazi invasion of Poland, Träger became a member of the Polish anti-Nazi resistance group Miecz i Pług (Sword and Plough) (MiP) in Pomerania.
In May 1943, Träger made his way clandestinely from Pomerania to Warsaw where he met with his contacts in the Home Army (specifically, intelligence department, Lombard) and transferred Roman's reports to them.
[6] After the war, in July 1945, he was arrested by the NKVD and imprisoned by the Polish secret police, as part of a general communist reprisal against former soldiers of the Home Army, and other anti-Nazi (but non-communist) resistance groups.
It was only in the 1970s, after some limited political and social reforms, that a commemorative plaque for both father and son was finally put up, at the kamienica in Wełniany Rynek (Wool Market) where Träger lived during the war.
