After the Austrian army withdrew to the other side of the swamps, prince Józef Poniatowski ordered his forces to withdraw towards Warsaw. However, since the city fortifications were in a very bad shape and the Saxonian expeditionary force withdrew towards their homeland, Poniatowski decided to leave Warsaw undefended and withdraw to several fortresses located nearby (most notably to Modlin Fortress and Serock). The capital was seized with little opposition, but it was a phyrric victory since the Austrian commander diverted most of his forces there at the expense of other fronts. In the following weeks Greater Poland was defended by the Corps of General Henryk Dąbrowski and the Polish cavalry seized Lwów. Finally, Poniatowski left only a small force near Warsaw to prevent the Austrians from leaving it and moved the rest of his forces southwards, which led to capturing the city of Kraków.
On October 14, 1809, the Treaty of Schönbrunn was signed between Austria and France. According to it the earlier state lost approximately 50 000 square kilometres of land inhabitated by over 1 900 000 people. The territories annexed by the Duchy of Warsaw included the lands of Zamość and Kraków as well as 50% of income of the Wieliczka salt mines.
