Starting in 1613, the growing inefficiencies of the central government, as well as an increase in foreign threats, led to the creation of a local territorial defense force, known as "żołnierz powiatowy" (district's soldiers raised by the powiat regions). The artillery formations, at first staffed by foreigners, were reformed in the 1630s, with a new tax levied to support them. This time also marked the introduction of the General of the Artillery rank into the Commonwealth armies. In the mid-17th century, the numbers of "wojsko zaciężne" and "kwarciane" proved insufficient, which led to the creation of "wojsko komputowe" (named after "komput", a document passed by the Sejm). "Wojsko komputowe" numbered (in 1649) 26,000. Simultaneously, "wojsko kwarciane" was disbanded, and "kwarta" directed towards the newly created artillery forces. Brzezinski notes that "wojsko kwarciane" was dissolved in the aftermath of its defeat at the Battle of Batih in 1652. In 1659, in the aftermath of numerous wars, the reformed army numbered around 54,000-60,000; it would decline from that point onward, as the country, impoverished by those wars, would not be able to support such a number.
