HDMS Langeland (1808)
The brig HDMS Langeland, launched in late 1808 and fitted out in 1809, was one of four brigs transferred to Norwegian ports from Denmark on 1 January 1810. From Norway she escorted Danish cargoes or harried enemy (British) merchant shipping. 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. She was sold into merchant service in 1827. Danish service

During the summer of 1809, three British gun brigs - the  brig-sloop  (18), brig  (16), and gun-brig  (14), operated in the far northern waters of Norway. They briefly occupied - after one failed attempt – the small town and sheltered harbour of Hammerfest near North Cape. Senior Lieutenant Thomas Joachim Lütken was captain of the Langeland from 1809 to 1814.I 1810 four brigs were transferred to Norwegian ports. In the spring of 1810 the two Danish-Norwegian brigs , 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. With the British gone, the coastal trade with Russia blossomed and a final convoy of the year was escorted into Trondheim., including 11 merchant ships. Norwegian Service
The Treaty of Kiel in January 1814 separated Norway from Denmark, leaving Norway with a navy of seven brigs (one of which was laid up) and a number of smaller craft. 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. Those who joined the Norwegian navy were eventually struck off the Danish lists. Many others obeyed Danish orders and returned to Denmark. Lütken, of the Langeland, was briefly arrested when he refused to hand over the ship to the newly constituted Norwegian State. The Lolland, which was larger than the other brigs in the new Norwegian Navy, became the command ship of the Norwegian navy’s brig squadron, whose primary mission was to escort food convoys from Jutland, protecting them from Swedish depredations. However, after a short war, Norway and Sweden united, forming a union that lasted until 1905. Lolland (Captain Ole Christopher Budde);
