the said alliance. During the Polish–Russian War of 1792 he left Warsaw, as he became unpopular with many of the patriotic and anti-Russian activists. He served under Russian diplomats Jacob Sievers and Yakov Bulgakov and was active in the background of the Grodno Sejm of 1793. During the Warsaw Uprising of 1794 in the Kościuszko Uprising he found brief refuge in the Saxon embassy, but was arrested on 17 April on the orders of the Polish provisional government. During the unrest of 28 June 1794 he was dragged from the jail and lynched (most sources specify he was publicly hanged), alongside some other unpopular individuals seen as supporters of the Targowica Confederation and traitors to the Polish cause. The hanged individuals, in addition to Boscamp-Lasopolski, included bishop Ignacy Jakub Massalski and prince Antoni Stanisław Czetwertyński-Światopełk.
