The state of Warsaw was established by Napoleon in 1807 from Polish lands ceded from Prussia. Duchy troops fought alongside the French during the 1809 war with Austria as well as the subsequent invasion of Russia. This failed campaign resulted in most of the duchy being retaken by Russia, while the rest was restored to Prussia in 1813.
