Skład i liczebność armii litewskiej podczas wojny z Turcją w latach 1683–1686

A historiography devoted to the reign of King John III Sobieski has so far lacked a detailed study on the Lithuanian army during the war with Turkey in 1683–1699. This article partially fills this gap as it precisely reconstructs the composition and numbers of the Lithuanian army in 1683–1686, i.e. during the expedition to Slovakia (1683), the campaigns in Zhvanets (1684) and Bukovina (1685), and military operations in Moldova (1686). Primary sources used for the article included treasury records, which are currently stored in Vilnius, i.e. reports of the Grand Treasurer of Lithuania, Benedict Paweł Sapieha, submitted at General Sejms in 1685 and 1689, as well as a short document that contains data from muster rolls of the 1680s. The records of the Grand Treasurer of Lithuania contain detailed lists of all Lithuanian military units which were part of the mercenary army and data on their numbers during the eight quarters of military service between 1683 and 1686. This material can be used for in-depth studies on the careers of military officers at that time, as well as the patronclient relationships between hetmans and their subordinates. The article also analyses the actions of the hetmans Kazimierz Jan Sapieha and Józef Bogusław Słuszko, whose aim was to strengthen the position of the Sapieha family and the royalist party, respectively, among soldiers and commanders.
