She took part in a successful cruise to the North Cape along with the brig Lougen in 1810 and was later taken into the fledgling Norwegian navy after the 1814 Treaty of Kiel.

[a] In the spring of 1810 the two Danish-Norwegian brigs Lougen, under the command of Captain J. N. Müller and Langeland sailed from Fredericksværn and reached Hammerfest on the 28 June where they joined with three gun-schooners - Nornen, Valkyren and Axel Thorsen, each of which was armed with a 24-pounder gun fore and aft.

The Dano-Norwegians hoped to find the expected British force in the waters of North Cape, for which there were few and poor charts, and no pilotage instructions.

However, American merchant ships warned Nightingale and Gallant (Snake had already left), of the enemy presence and they disappeared – apparently to Greenland to escort a convoy of British whalers.

A number of naval officers refused to accept service in the new Norwegian navy until released by the Danish king to whom they had sworn loyalty.
