Input: Question: What did Johann-Ulrich Dietegan (Comte) v. Salis-Seewis do for a career? Passage:The poet colleagues shared a sense of Sturm und Drang and empathy, calling it the "Bündner Nachtigall" (Graubünden nightingale). Salis-Seewis returned to Switzerland in 1791, living in Chur and marrying there, on 26 December 1793, the 22-year-old Ursina v. Pestalozzi (Chur 29 September 1771 - Malans 27 June 1835). They had two sons; Johann-Ulrich Dietegan (Comte) v. Salis-Seewis (1794–1844) and Johann-Jakob (Freiherr) v. Salis-Seewis (1800–1881). He had a lively involvement in the political changes in his homeland over the next years lively involved, endorsed the alliance of the Three Leagues of Switzerland to the new France, and the proclaimed Helvetic Republic. After the area was occupied by Austria in the following year, Salis-Seewis and his family had to flee to Zurich. There, he was appointed inspector general of the Helvetican troops. This activity brought him the nickname "poet general". He later went to Bern and received a place on the Court of cassation. When the Act of Mediation was issued by Napoleon Bonaparte in 1803, it became possible for Salis-Seewis to return to Graubünden. There he held several public offices until 1817, then he withdrew as Swiss federal colonel. His father had died two years before.
