actions that contributed to the OUN-B's weapon stockpiles. In addition, blackmailing Jews served as a source of added finances. During the time that the OUN-B in Volhynia was avoiding conflict with the German authorities and working with them, resistance to the Germans was limited to Soviet partisans on the extreme northern edge of the region, to small bands of OUN-M fighters, and to a group of guerillas knowns as the UPA or the Polessian Sich, unaffiliated with the OUN-B and led by Taras Bulba-Borovets of the exiled Ukrainian People's Republic. By late 1942, the status quo for the OUN-B was proving to be increasingly difficult. The German authorities were becoming increasingly repressive towards the Ukrainian population, and the Ukrainian police were reluctant to take part in such actions. Furthermore, Soviet partisan activity threatened to become the major outlet for anti-German resistance among western Ukrainians. By March 1943, the OUN-B leadership issued secret instructions ordering their members who had joined the German police in 1941–1942, numbering between 4,000 and 5,000 trained and armed soldiers, to desert with their weapons and to join the units of the OUN-B in Volyn. Borovets attempted to unite his UPA, the smaller OUN-M and other nationalist bands, and the OUN-B underground into an all-party front. The OUN-M agreed while the OUN-B refused, in part due to the insistence of the OUN-B that their leaders be in control of the organization. After negotiations failed, the OUN commander Dmytro Klyachkivsky coopted the name of Borovets' organization, UPA, and decided to accomplish by force what could not be accomplished through negotiation: the unification of Ukrainian nationalist forces under OUN-B control. On 6 July, the large OUN-M group was surrounded and surrendered, and soon afterward most of the independent groups disappeared; they were either destroyed by the Communist partisans or the OUN-B or joined the latter. On 18 August 1943, Taras Bulba-Borovets and his headquarters were surrounded in a surprise attack by an OUN-B force consisting of several battalions. Some of his forces, including his wife, were captured, while five of his officers were killed. Borovets escaped but refused to submit, in a letter accusing the OUN-B of among other things: banditry; of wanting to establish a one-party state; and of fighting not for the people but in order to rule the people. In retaliation, his wife was murdered after two weeks of torture at the hands of the OUN-B's
