Belarus, the Leningrad Oblast, the Kalinin Oblast, the Smolensk Oblast, the Oryol Oblast and Ukraine within an area 1000 km along the front and 750 km wide. Reportedly, more than 230,000 rails were destroyed, along with many bridges, trains and other railroad infrastructure. The operation seriously incapacitated German logistics and was instrumental in the Soviet victory in Kursk battle. Operation Concert, September 19 – November 1, 1943. "Concerto" was a major operation of partisan formations against the railroad communications intended to disrupt the German reinforcements and supplies for the Battle of the Dnieper and on the direction of the Soviet offensive in the Smolensk and Homel directions. Partisans from Belarus, Karelia, the Kalinin Oblast, Lithuania, Latvia, Estonia and the Crimea participated in the operations. The area of the operation was 900 km along the front (excluding Karelia and Crimea) and 400 km wide. Despite bad weather that only permitted the airlift of less than a half of the planned supplies, the operation lead to a 35–40% decrease in the railroad capacity in the area of operations. This was critical for the success of Soviet military operations in the autumn of 1943. In Belarus alone the partisans claimed the destruction of more than 90,000 rails along with 1,061 trains, 72 railroad bridges and 58 Axis garrisons. According to the Soviet historiography, Axis losses totaled more than 53,000 soldiers. Battle of Połock-Lepel, April 1944. Major battle between Belarusian partisans and German punitive expeditions. Battle of Borysów-Begoml, April 22 – May 15, 1944. Major battle between Belarusian partisans and German punitive expeditions. Operation Bagration, June 22 – August 19, 1944. Belarusian partisans took major part in the Operation Bagration. They were often considered the fifth front (along with the 1st Baltic Front, 1st Belorussian Front, 2nd Belorussian Front and 3rd Belorussian Front). Upwards of 300,000 partisans took part in the operation. Pro-independence resistance In 1941, a significant part of the Belarusian pro-independence movement chose to collaborate with the Nazis following mass Soviet repressions in Belarus and discrimination of Belarusians in the Second Polish Republic throughout the preceding decades. However, as the war progressed, parts of the collaboration movement became less loyal to the Germans. Germans reacted with repressions. The Catholic priest Vincent Hadleŭski, who was the leader of the Belarusian Independence Party, was arrested by the German police on December 24, 1942, and executed in the Maly Trostenets extermination camp.
