[1][2] Following his marriage, Borghese was made regimental chief of the Tirailleurs du Po, which was recruited from the region that he governed.

Shortly afterwards, he was made a Prince of the French Empire and subsequently promoted to squadron chief in the Imperial Guard in 1805 (as an honorary rank).
