Cause

Austria joined a coalition with Britain against Napoleonic France in 1809. As part of this broader struggle, Austria moved to attack the Duchy of Warsaw, a French-allied Polish state, seeking to suppress Polish military power and neutralize Napoleon's eastern flank.

Event

Polish forces of the Duchy of Warsaw, aided by Saxony and later Russia, resisted and repelled the Austrian invasion. After defeating the Austrians at the Battle of Raszyn, Polish troops deliberately abandoned Warsaw to launch an offensive, recapturing Kraków, Lwów, and other historic Polish territories.

Consequence

The Austrians were drawn into a futile pursuit and compelled to abandon Warsaw. Poland recovered significant pre-partition territories, and the campaign demonstrated the military viability of the Duchy of Warsaw as a French ally, influencing the eventual Peace of Schönbrunn in 1809.
