shore and therefore inside Norwegian waters. The Norwegians therefore protested that the attack had violated Norwegian territorial waters and that E30 had dived away and not remained on the surface. The neutrality violation had been so well documented that the UK government later issued an apology to its Norwegian counterpart, and revised its instruction to submarines operating close to neutral coastlines. Inter-war period By the end of the First World War the Norwegian torpedo boat fleet had been worn down by constant service and 14 of the vessels were decommissioned and disposed of in 1920. Twenty-three torpedo boats, including Kjell, were obliged to continue in service due to budgetary restrictions despite being long outdated and ready for replacement. Although officially still in service the torpedo boats spent most of the inter-war period in port, only being equipped for exercises some two to three months every year. Intercepting smugglers 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 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. Second World War Norwegian service Neutrality protection 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. Rescuing a Norwegian aircrew 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.
