Article speaks about Army Krajova Vilnius district organisational structure, forms of armed fighting and various aspects of the daily life of Polish partisans. The chronological boundaries of the articlc are the beginning of 1944 (intensive development and surge of activity of Polish partisan squads) to July 1944 (Soviet return and re-occupation). The author of the article used original AK documents, reports and memoirs of former Polish partisans. The article also examines such aspects of AK activity as systems of squad liaisons with district commanders, functioning of various underground services (intelligence, counterintelligence, médical assistance), armament, uniforms, military training of Polish partisans, types of military actions, relations with the civilian population, and also Lithuanian-Polish relations during the years of Nazi occupation. The author does not shy away from examining thorny aspects of Lithuanian-Polish relations. The squirmishes between armed Lithuanian police divisions and Polish partisans caused tensions in Lithuanian-Polish relations; innocent blood of Lithuanians and Poles was spilled. In the authors opinion, such a merciless war between Poles and Lithuanians seemed inevitable to both parties, but in fact it was a waste of strength in the face of the approaching Soviet threat. Due to these events the Polish-Lithuanian dialogue continues to be difficult to this day. Historical research performed by historians of both countries went mutually ignored. Lack of good will, partiality, and nationalistic convictions impeded discussions. In the opinion of the author, both Poles and Lithuanians must diligently examine those events and evaluate them only afterwards. Polish and Lithuanian historians should undertake joint scientific research and harmonise their opinions
