Obóz Polski Walczącej (OPW, Camp of Fighting Poland, or Fighting Poland Movement) was a minor part of the Polish resistance movement in World War II. Created in 1942-44 and centered in Warsaw [1], its members were mostly composed of the former political party, Obóz Zjednoczenia Narodowego (Camp of National Unity, or 'Ozon'), part of the Sanacja movement. Among the organizers of this movement was marshal Edward Rydz-Śmigły, who proposed its name, and Julian Piasecki[2][3], who became its commandant. It was militarily subordinate to the Armia Krajowa from 1943 and eventually merged with Konwent Organizacji Niepodległościowych (The Council of Independence Organizations) into Zjednoczenie Organizacji Niepodległościowych (The Union of Independence Organizations).
