Appraising the activity of the Union of Polish Patriots on the basis of radio broadcasts in Polish, one can come to two conclusions. First, the Union of Polish Patriots was an organization dealing with Poles and Jews staying on the territory of the Soviet Union. After the severance of diplomatic relations with the Soviet Union the aforementioned organization undermined the legitimacy of the Polish government in London. It was also responsible for passing an ideological declaration, which consisted of theses relating to the post-war borders of Poland. It should be noted however, that all postulates the declaration included (inter alia the subject matter of the post-war Polish-Soviet demarcation) were in fact solutions proposed by the USSR’s authorities. The board of the Union of Polish Patriots organized in war conditions both cultural and educational life for hundreds of thousands of Polish citizens. They were provided with material being to the greatest extent possible and thanks to it countless compatriots lived through that traumatic period. Broadcasts of the Tadeusz Kosciuszko Polishlanguage radio station never misrepresented actions of the Union of Polish Patriots. It arose from the fact that the radio station was functioning and acting as propaganda of its authorities, that is the USSR.
