In the interval between these visits, he fought for Poland during the Polish–Russian War of 1792 (was one of the early recipients of the "Virtuti Militari" decoration for valour there), which preceded the Second Partition of Poland. He was arrested on his way to Poland at Brussels by the Austrian government. After the Third Partition of Poland the Czartoryski estates were confiscated, and in May 1795 Adam and his younger brother Konstanty were summoned to Saint Petersburg.
