Poles. A skirmish ensued, in which 4 Poles were killed and 8 wounded. German losses were estimated at 15 killed and 22 wounded. Those who were not caught, divided themselves into two groups and headed north, to Bezirk Bialystok. On June 11, 1943, the UBK forces under Major Stanislaw Pieciul (Radecki) of the 4th Battalion engaged the Germans near the village of Pawly (Bielsk Podlaski County). 25 Poles and approximately 40 Germans died. In July 1943 the Uderzeniowe Bataliony Kadrowe units, active in Bezirk Bialystok, consisted of five Battalions. Altogether, there were 200 fighters, and during a number of skirmishes with the Germans (including the 1943 Polish underground raid on East Prussia), 138 of them were killed. These heavy losses were criticized by the headquarters of the Home Army, who claimed that the UBK was profusely using lives of young Polish soldiers. On August 17, 1943, upon the order of General Tadeusz Bór-Komorowski, the UBK was included into the Home Army. Soon afterwards, all battalions were transferred to the area of Novogrudok. By autumn 1943, the partisan force in BSSR totalled about 153,700, and by the end 1943 about 122,000, with about 30,800 put behind the frontline in the course of liberation of eastern parts of BSSR (in the end of 1943). After the liberation of BSSR, about 180,000 partisans joined the Soviet Army in 1944. During the 1941—1944 period, the turnaround in the Soviet partisan force in Belarus was about 374,000, about 70,000 in urban underground, and about 400,000 in the reserve of the partisan force. Among Soviet partisans in Belarus were people of 45 different ethnic backgrounds and 4,000 foreigners (including 3,000 Poles, 400 Czechs and Slovaks, 300 Yugoslavians, etc.). Around 65% of Belarusian partisans were local people. On September 22, 1943, Kube was assassinated in his Minsk home by a bomb as part of Operation Blow-Up; the bomb was placed by a Soviet partisan Yelena Mazanik, a Belarusian woman who had managed to find employment in Kube's household as a maid and presumably became his mistress in order to assassinate him. 1943–1944 The partisan movement was so strong that by 1943–44 there were entire regions in occupied Belarus, where Soviet authority was re-established deep inside the German held territories. There were even partisan kolkhozes that were raising crops and livestock to produce food for the partisans. During the battles for liberation of Belarus, partisans were considered the
