The Polish–Russian War of 1792 was fought between the Polish–Lithuanian Commonwealth on one side, and the Targowica Confederation and the Russian Empire under Catherine the Great on the other. The war took place in two theaters: northern in Lithuania and southern in what is now Ukraine. In both, the Polish forces retreated before the numerically superior Russian forces, though they offered significantly more resistance in the south, thanks to the effective leadership of Polish commanders Prince Józef Poniatowski and Tadeusz Kościuszko. During the three-month-long struggle several battles were fought, but no side scored a decisive victory. Russia took 250,000 square kilometres (97,000 sq mi), while Prussia took 58,000 square kilometres (22,000 sq mi) of the Commonwealth's territory. This event reduced Poland's population to only one-third of what it was before the First Partition.
