soldiers each, as well as one border guard regiment and one unit were starting to relocate there in order to reinforce them. During late 1944 and the first half of 1945, according to Soviet data, the UPA suffered approximately 89,000 killed, approximately 91,000 captured, and approximately 39,000 surrendered while the Soviet forces lost approximately 12,000 killed, approximately 6,000 wounded and 2,600 MIA. In addition, during this time, according to Soviet data UPA actions resulted in the killing of 3,919 civilians and the disappearance of 427 others. Despite the heavy losses, as late as summer 1945, many battalion-size UPA units still continued to control and administer large areas of territory in Western Ukraine. In February 1945 the UPA issued an order to liquidate kurins (battalions) and sotnya's (companies) and to act predominantly by chotys (platoons). Spring 1945–late 1946 After Germany surrendered in May 1945, the Soviet authorities turned their attention to insurgencies taking place in Ukraine and the Baltics. Combat units were reorganised and special forces were sent in. One of the major complications that arose was the local support the UPA had from the population. Areas of UPA activity were depopulated. The estimates on numbers deported vary; officially Soviet archives state that between 1944 and 1952 a total of 182,543 people were deported while other sources indicate the number may have been as high as to 500,000. Mass arrests of suspected UPA informants or family members were conducted; between February 1944 and May 1946 over 250,000 people were arrested in Western Ukraine. Those arrested typically experienced beatings or other violence. Those suspected of being UPA members underwent torture; reports exist of some prisoners being burned alive. The many arrested women believed to be affiliating with the UPA were subjected to torture, deprivation, and rape at the hands of Soviet security in order to "break" them and get them to reveal UPA members' identities and locations or to turn them into Soviet double-agents. Mutilated corpses of captured rebels were put on public display. Ultimately, between 1944 and 1952 alone as many as 600,000 people may have been arrested in Western Ukraine, with about one-third executed and the rest imprisoned or exiled. The UPA responded to the Soviet methods by unleashing their own terror against Soviet activists, suspected collaborators and their families. This work was particularly attributed to the Sluzhba Bezbeky (SB), the anti-espionage wing of the UPA. In a typical incident
