The main theme in the Polish science and fiction literature, which in the postwar era evolved primarily in exile (in the works of Józef Mackiewicz and other authors whose interest was concentrated on Second World War times), are issues related to the lack of understanding and reconciliation between the Polish resistance movement, the history of the Home Army and the guerrilla groups of various nationalities (Belarusian, Lithuanian, Ukrainian, Russian) in the Polish Eastern Borderlands occupied by the Nazis and national organizations and liberation movements of nations that sought their own solutions to national problems by means of collaboration with the occupants. Misunderstandings, war clashes among themselves caused fatal misfortune, irreparable damage to the lives of these people and for the common cause against the occupant. At first the Polish literature was dominated by the desire to find the culprits of this situation among neighbours, among others to prove the guilt of the Belarusians in what formed in Polish Eastern Borderland during the war and occupation, then the creation of the communist regime, when, supposedly, Belarusians willingly and on a mass scale served in the Soviet authorities “gosbezopasnosti” and in the ranks of the Polish Department of Security (UB). Such a drive in the works of writers and scientific studies of recent decades is changing to a more objective approach and indepth analysis of the dramatic situation in which were nations of Eastern Europe, deceived by their own leaders, blinded by false illusions, pulled into a fratricidal war. In Polish literature, whose attention is paid to the situation of the Belarusian minority in post-war “People’s Poland” – situation in many aspects hard and unlawful – new intonations of repentance and reconciliation can be heard much louder. Evidence of this poetic light Belarus-Dobrorus image can be.
