On 9 March, the Swedish mission to Copenhagen demanded that Christian Frederik be disinherited from succession to the Danish throne and that European powers should go to war with Denmark unless he disassociated himself from the Norwegian independence movement. Niels Rosenkrantz, the Danish foreign minister, responded to the Swedish demands by asserting that the Danish government in no way supported Norwegian independence, but that they could not vacate border posts they did not hold. The demand to disinherit Christian Frederik was not addressed. Swedish troops massed along the border, and there were daily rumors of an invasion. In several letters to von Essen, commander of the Swedish forces at Norway's borders, Bernadotte referred to Christian Frederik as a rebel and ordered that all Danish officials who did not return home were to be treated as outlaws. But the regent countered by confiscating all navy vessels stationed in Norway and arresting officers who were planning to sail them to Denmark.
