A member of Tadeusz Kościuszko's conspiracy, he took part in the Warsaw Uprising of 1794 as one of the leaders of the Polish forces,[2] possibly as the commanding officer of his regiment.
[1] Following the Polish victory he was one of the signatories of the act of accession of the city of Warsaw to Kościuszko's Uprising and soon afterwards became one of the members of War Council of the land of Mazovia.
[1] Wounded during the disastrous Battle of Maciejowice, he nevertheless managed to lead his forces out of the Russian encirclement and reach Warsaw, where king Stanisław August Poniatowski promoted him to the rank of Colonel.
[1] His missions however failed to gather support for the Polish cause and eventually, after the death of Catherine II of Russia, he followed Dąbrowski to St. Petersburg, where the two were pardoned and joined Russian military service.
[1] He is best known as the author of memoirs, published initially in 1807 as Historia polska czyli Rys panowania Stanisława Augusta króla polskiego (Polish History, that is an outline of the rule of Stanisław August, the king of Poland).
