After the unhappy outcome of the fight Oginski fled, but was able to return in 1802 with the permission of Czar Alexander I. to his estate Zalesie near Vilnius.
After the Peace of Tilsit he went to France and Italy, returning to Poland in 1810 as senator und privy councillor. In 1815 he returned to Italy.
He was also an author and composer. His compositions include national songs and dances. One well-known composition is his "Farewell from the Fatherland" ("Abschied vom Vaterland"). His Mémoires sur la Pologne et les Polonais depuis 1788–1815 shed light on the period.
