Zamki i drogi na białoruskim Podźwiniu w czasie wojny inflanckiej (1558–1583)

The study of warfare in Belarusian Podvine (Polack and Viciebsk Voivodeships along with the Braslaŭ district) throughout the Livonian Wars has garnered considerable scholarly attention. However, several pivotal aspects have not been explicated, including the objectives behind various war campaigns and the efficacy of strategies employed by the adversaries – the Tsardom of Muscovy and the Grand Duchy of Lithuania (Polish-Lithuanian Commonwealth from 1569). A thorough analysis of military logistics, with its focal points being transportation routes and fortifications, is essential for a comprehensive insight into these issues. The assessment of military potential associated with Lithuanian and Muscovite castles is most effectively executed through an in-depth analysis of their arsenals and garrisons. Evidently, the supply of weaponry indicated that Vilnius anticipated an intense struggle for control over the Daugava River, which was significant for dominance in Livonia. The Polack campaign led by Ivan the Terrible during the winter of 1562/1563 should be evaluated as a rational, yet daring manoeuvre. This endeavour instigated the construction of a robust network of fortresses in the occupied territories, the upkeep of which proved very expensive, and the lack of waterways further exacerbated the problem. Conversely, the Lithuanians adeptly devised a defensive framework on the left bank of the Daugava River, and successfully thwarted efforts to block Viciebsk – a city that maintained control over river transportation. The skilful utilisation of roads and watercourses within Podvine emerged as a pivotal factor contributing to the triumphs of Stephen Batory’s military campaigns from 1579 to 1582.
