Zygmunt Szendzielarz (12 March 1910 – 8 February 1951, nom de guerre "Łupaszka".) was the commander of the Polish 5th Wilno Brigade of the Home Army (Armia Krajowa) and after the Second World War fought against the Red Army. The unit also committed the Dubingiai massacre, murdering twenty seven Lithuanian civilians on 23 June 1944. Following the postwar Soviet takeover of Poland he was arrested, accused of numerous crimes, and executed in Warsaw's Mokotów Prison as an anti-communist diehard soldier. In 1993, after the fall of communism, he was rehabilitated and declared innocent of all charges
