In April 1944 a special operational group was established, headed by D. K. Sukaczew, dismissed for this purpose from the oblast on 25 January 1944, which was to deal with reconstruction in triggered peripheral and district areas and municipal executive committees.
[2] And so, In May 1944, after several months of absence, Sukaczew returned to BZP, already as the chairman of the Regional Executive Committee of the Council of Workers' Delegates in Bialystok.
The situation was complicated by the fact that the Red Army stopped at the end of September on the Narew – Biebrza – Augustów Canal – Czarna Hańcza rivers, which caused that part of the Augustów region and located on the left bank of the Narew, the areas of the Grajewski, Łomżyński and Ostrołęka regions remained under German control.
[3] On 3 July 1944, at the next meeting of the Białystok Obkom, it was decided to start publishing 4–6 times a month in Polish, with a circulation of 500 copies of the newsletter with political information.
Based on the preparations, it seems nobody from Belarusian party activists at the central, and even more peripheral level, did not doubt that the Bialystok region was, is and will be inseparable part of the Byelorussian SSR.
[5][6] The Region consisted of 24 districts: Augustow, Bialystok, Belsky, Bryansk, Volkovysk, Grodno, Grajewo, Dombrowski, Zabludavski, Zambravski, Kolnavski, Krynkovsky, Lapski, Lomzhinsky, Monkavski (in the same year was renamed to Knyshynski), Porechsky (in the same year transferred to the Lithuanian SSR), Sakolkavski, Sapotskinsky, Skidelsky, Svislochsky, Snyadovski, Tsehanovetsky, Chyzhavski and Yadvabnavski.
During the meeting of the Central Committee on 1 December 1939, Ponomarenko, speaking of Łomża, pointed out that this is a city inhabited by Poles and Jews, heavily damaged by military operations, where they are at peace with the new authorities.
