In the decentralized state and treasury, the military potential was hampered by the inefficient fiscal apparatus and insufficient taxation. The Commonwealth in the second half of the 17th century developed huge indebtedness in respect to its own armed forces. Military confederations or rebellions, through which the army "collected" its own pay typically from royal and church estates, were getting increasingly common. Hetman Sobieski was unable to follow up his Khotyn victory in part because the unpaid Lithuanian and Crown troops left. The Commonwealth was able to field a 60,000 army (plus the unreliable pospolite ruszenie) at the very most, at times when the Habsburg Monarchy or the Tsardom of Russia were capable of an effort twice that size. After the Cossack-Tatar wars and to a lesser degree after 1655, the armed forces had to be rebuilt almost completely.
