HNoMS Kjell

For Kjell the 1922 exercise season turned out somewhat unusual as she was deployed against alcohol smugglers on the coast as part of the enforcement of the 1916–1927 Norwegian prohibition. During 20 days in September 1922 Kjell operated off Færder in Tjøme, soon earning the nickname Terror of the smugglers (Norw. Smugglernes skrekk) by confiscating on average 1,500 litres (329.95 imp gal) of spirits a day. At the conclusion of the 20-day anti-smuggling cruise each member of the torpedo boat's crew received the then-substantial amount of 382 Norwegian kroner in prize money.[12]

At the outbreak of the Second World War the Norwegian torpedo boat force was again deployed guarding the coastline against neutrality violations. Kjell was at that time part of the 2. Torpedo boat Division in the Kristiansand section of the 1st Naval District, covering the southernmost part of the Norwegian coastline. As had been the case during the First World War the torpedo boats were once more spread singly along the coastline.[13][14]

One incident in which Kjell was involved was when she on 14 October 1939 rescued from the skerry Østre Flandern near Flekkerøy the three-man crew of Marinens Flyvebaatfabrikk M.F.11 F.320, which had made an emergency landing after suffering engine failure. Kjell recovered the Royal Norwegian Navy Air Service crew in the early afternoon of 14 October, while the wreck of F.320 was retrieved by the patrol boat Lyngdal the next day.[15]

German dead being brought ashore for burial after the Altmark Incident

One of the tasks given to the Norwegian torpedo boat force as part of their renewed neutrality protection duties was the escort and inspection of vessels belonging to the warring parties. One of these missions included the control and escort of the German auxiliary tanker Altmark in February 1940. Altmark was returning to Germany after having supported the German pocket battleship Admiral Graf Spee in the South Atlantic. On her return voyage to Germany she was carrying 299 British merchant sailors as prisoners of war (POWs), and entered Norwegian waters north of Trondheimsfjord on 14 February 1940. The transport of POWs through neutral territorial waters was not in violation of public international law, and as Norwegian authorities feared an incident between the German ship and the Royal Navy the ship was allowed passage through the restricted areas at Bergen. The passage at Bergen was in violation of official Norwegian neutrality regulations as the tanker was a state-operated vessel of a warring party.[16] As Altmark proceeded southwards to Germany she was escorted along the way by various Norwegian warships.[16] On the day after she entered Norwegian waters, 15 February, the Altmark was spotted by British reconnaissance aircraft and soon after confronted by a force of six Royal Navy destroyers. In an effort to avoid capture Altmark sought shelter in the Jøssingfjord, in the area between Egersund and Flekkefjord, now under the escort of Kjell and fellow torpedo boat Skarv.[17] Ignoring protests from the Norwegian naval vessels, which commanders were under direct orders not to fire at the British,[16] the destroyer HMS Cossack entered Jøssingfjord at 2220hrs on 16 February and boarded the German ship, killing six, mortally wounding one of the German crew and freeing the British prisoners. The failure of Kjell and the other Norwegian warships to intervene in the blatant neutrality violation led Hitler to speed up plans for a German invasion of Norway, six days after the incident appointing General Nikolaus von Falkenhorst as commander of the operation.[17] One of the immediate German reactions to the incident was a demand that the commanders of Kjell and Skarv be dismissed, although this was quickly dropped following the recommendation of the German legation in Oslo.[16] The Norwegian government on its part issued strong protests to the UK government, President of the Norwegian Parliament C. J. Hambro stating that the united Norwegian parliament and people protested the British intrusion at Jøssingfjord.[17]

Another incident occurred the following month when, on 27 March 1940, the German submarine U-21 accidentally ran aground at Oddene near Ryvingen south-east of Mandal. Marinens Flyvebaatfabrikk M.F.11 F.328 landed near the U-boat and guarded it until Norwegian naval vessels reached the scene and interned the crew. U-21 was towed to Kristiansand the next day under escort of Kjell, Teist, the destroyer Odin and the B-class submarine B-2.[18]

On 8 April 1940, the day before the German invasion, Kjell was in Kristiansand carrying out repairs which were finished by afternoon. The next morning she was ordered to nearby Marvika naval base to take on board torpedoes. However, before the vessel could be made war ready orders came through from the commander of the local naval section that resistance to the German invasion in the Kristiansand area was to cease. As the Germans occupied Marvika Kjell was allowed to move to nearby Vigebukta bay in the Topdalsfjord. On 11 April the torpedo boat was seized by German infantry and at 1830hrs the German war flag was raised, signalling the ship's transfer to Kriegsmarine service.[3]

Initially renamed KT1 and used as a Vorpostenboot (outpost boat), she was then rebuilt as a minesweeper under the name NK.02 Dragoner. Serving as a patrol boat and escort vessel on the coast of occupied Norway, Dragoner was sailing alone off Ryvingen near Mandal when she was discovered and attacked by six No. 248 Squadron RAF de Havilland Mosquito fighter bombers on 28 September 1944. After a brief and futile fight she was sunk by a combination of autocannon fire and a depth charge exploding underneath her midship section. Of the 25 Germans on board at the time of the sinking 18 survived, seven of whom were wounded. The attacking RAF aircraft suffered no damage from the German return-fire and all returned to base.[2][19][20]
