Although historians say the Holy Cross Mountains Brigade collaborated with the Nazis, a representative of the veterans, Jan Józef Kasprzyk, sought to deny such a link.
Kasprzyk described the claims of collaboration as a product of postwar communist propaganda meant to smear the unit’s legacy.
The official rehabilitation of the brigade began when Polish Prime Minister Mateusz Morawiecki honored its members at a cemetery in Munich in February 2018.
Morawiecki asserted at a news conference the same day that there were some “Jewish perpetrators” of the Holocaust.
