During the [[Great Northern War]] the Grand Ducal Lithuanian Army no longer defended the country and the [[Magnates of Poland and Lithuania|Lithuanian magnates]]' private armies supported different sides.<ref name="lt-military-medieval" /> Throughout the 18th century, many [[Confederation (Poland–Lithuania)|confederations in the Polish–Lithuanian Commonwealth]] sought different political goals.<ref name="lt-military-medieval" /> The [[Bar Confederation]] (1768–1772), which happened partly in Lithuania, attempted but failed to stem the increasing influence of Imperial Russia and the [[First partition of the Polish-Lithuanian Commonwealth]] followed.<ref name="lt-military-medieval" /> In the face of the possible loss of independence, military reforms in the [[Four Years' Sejm]] (1788–1792) significantly expanded the Lithuanian army, which reached a strength of 17,500.<ref name="lt-military-medieval" /><ref name=":0" /> Attempts to make the Commonwealth's armies equal those of neighbouring [[absolute monarchy|absolute monarchies]] were unsuccessful and the unsuccessful [[War of 1792]] resulted in the [[Second Partition of the Polish-Lithuanian Commonwealth|Second Partition]].<ref name="lt-military-medieval" />

The Polish and Lithuanian armies put up a spirited fight against the [[Imperial Russian Army]] and the [[Prussian Army]] in the [[Kościuszko Uprising]].<ref name="lt-military-medieval" /> In addition to regular forces, many ''ad hoc'' units such as the [[Vilnian National Guard]] also fought, as well as many irregular units.<ref name="lt-military-medieval" /> In the end, the Uprising was defeated and much of the remainder of the Grand Ducal Lithuanian Army was lost in the [[Battle of Praga]] on 4 November 1794.<ref name="lt-military-medieval" /> With the uprising defeated, the Grand Duchy of Lithuania and the [[Crown of the Kingdom of Poland|Kingdom of Poland]] ended with the [[Third Partition of the Polish-Lithuanian Commonwealth|Third Partition]], and their respective armies being disbanded.<ref name="lt-military-medieval" />
