German occupation of Norway The occupation of Norway by Nazi Germany started with the German invasion of Norway on 9 April 1940 , and ended on 8 May 1945 , after the capitulation of German forces in Europe . Throughout this period , Norway was continuously occupied by the " Wehrmacht " . Civil rule was effectively assumed by the " Reichskommissariat Norwegen " ( " Reich Commissariat of Norway " ) , which acted in collaboration with a pro - German puppet government , while the legitimate Norwegian king and government continued to operate in exile from London . This period of military occupation — usually referred to as the " war years " or " occupation period " in Norway — had defining significance for Norwegian society , and it is only recently that Norway considers itself as having passed out of the " post - war era " . Background . Having maintained its neutrality during World War I , Norwegian foreign and military policy since 1933 was largely influenced by three factors : These three factors met resistance as tensions grew in Europe in the 1930s , initially from Norwegian military staff and right - wing political groups , but increasingly also from individuals within the mainstream political establishment and , it has since come to light , by the king , behind the scenes . By the late 1930s , the Norwegian parliament had accepted the need for a strengthened military and expanded the budget accordingly , even by assuming national debt . As it turned out , most of the plans enabled by the budgetary expansion were not completed in time . Pre - war relations with the United Kingdom . Although the respect of neutrality remained the highest priority until the invasion was a " fait accompli " , it was known throughout the government that Norway , above all , did not want to be at war with the United Kingdom . By the autumn of 1939 , there was an increasing sense of urgency that Norway had to prepare , not only to protect its neutrality , but indeed to fight for its freedom and independence . Efforts to improve military readiness and capability , and to sustain an extended blockade , were intensified between September 1939 and April 1940 . Several incidents in Norwegian maritime waters , notably the Altmark incident in Jøssingfjord , put great strains on Norway ' s ability to assert its neutrality . Norway managed to negotiate favourable trade treaties both with the United Kingdom and Germany under these conditions , but it became increasingly clear that both countries had a strategic interest in denying the other access to Norway . The government was also increasingly pressured by Britain to direct ever larger parts of its massive merchant fleet to transport British goods at low rates , as well as to join the trade blockade against Germany . In March and April 1940 , British plans for an invasion of Norway were prepared , mainly in order to reach and destroy the Swedish iron ore mines in Gällivare . It was hoped that this would divert German forces away from France , and open a war front in south Sweden . It was also agreed that mines would be laid in Norwegian waters ( Operation Wilfred ) and that the mining should be followed by the landing of troops at four Norwegian ports : Narvik , Trondheim , Bergen and Stavanger . Because of Anglo - French arguments , the date of the mining was postponed from 5 April to 8 April . The postponement was catastrophic . On 1 April , Adolf Hitler had ordered the German invasion of Norway to begin on 9 April ; so , when on 8 April , the Norwegian government was preoccupied with earnest protest about the British mine - laying , the German expeditions were well on their way . German invasion . On the pretext that Norway needed protection from British and French interference , Germany invaded Norway for several reasons : Through neglect both on the part of the Norwegian foreign minister Halvdan Koht and minister of defence Birger Ljungberg , Norway was largely unprepared for the German military invasion when it came on the night of 8 – 9 April 1940 . Consistent with Blitzkrieg warfare , German forces attacked Norway by sea and air as Operation Weserübung was put into action . The first wave of German attackers counted only about 10 , 000 men . The German ships came into the Oslofjord , but was stopped when the Krupp built artillery and torpedoes of Oscarsborg Fortress sank the German flagship " Blücher " and sank or damaged the other ships in the German task force . Blücher transported the forces that would ensure control of the political apparatus in Norway , and the sinking delayed the Germans , so that the King and government had the chance to escape from Oslo . In the other cities that were attacked , the Germans faced only weak or no resistance . The surprise , and the lack of preparedness of Norway for a large - scale invasion of this kind , gave the German forces their initial success . The major Norwegian ports from Oslo northward to Narvik ( more than away from Germany ' s naval bases ) were occupied by advance detachments of German troops . At the same time , a single parachute battalion ( the first ever employed in warfare ) took the Oslo and Stavanger airfields , and 800 operational aircraft overwhelmed the Norwegian population . Norwegian resistance at Narvik , at Trondheim ( the strategic key to Norway ) , at Bergen , at Stavanger , and at Kristiansand was overcome very quickly ; and Oslo ' s effective resistance to the seaborne forces was nullified when German troops from the airfield entered the city . The first troops to occupy Oslo entered the city brazenly marching behind a German military brass band . On establishing a foothold in Oslo and Trondheim , they launched a ground offensive against scattered resistance inland in Norway . Allied forces attempted several counterattacks , but all failed . While resistance in Norway had little military success , it had the significant political effect of allowing the Norwegian government , including the Royal family , to escape . Most notably , the German cruiser , which carried the main forces to occupy the capital , was sunk in the Oslofjord on the first day of the invasion . An improvised defence at Midtskogen also prevented a German raid from capturing the king and government . Norwegian mobilisation was hampered by the loss of much of the best equipment to the Germans in the first 24 hours of the invasion , the unclear mobilisation order by the government , and the general confusion caused by the tremendous psychological shock of the German surprise attack . The Norwegian Army rallied after the initial confusion and on several occasions managed to put up a stiff fight , delaying the German advance . However , the Germans proved unstoppable due to their superior numbers , training and equipment . The Norwegian army therefore planned its campaign as a tactical retreat while awaiting reinforcements from Britain . British and French troops began to land at Narvik on 14 April . Shortly afterward , British troops were landed also at Namsos and at Åndalsnes , to attack Trondheim from the north and from the south , respectively . The Germans , however , landed fresh troops in the rear of the British at Namsos and advanced up the Gudbrandsdal from Oslo against the force at Åndalsnes . By this time , the Germans had about 25 , 000 troops in Norway . By 2 May , both Namsos and Åndalsnes were evacuated by the British . On 5 May , the last Norwegian resistance pockets remaining in South and Central Norway were defeated at Vinjesvingen and Hegra Fortress . In the north , German troops engaged in a bitter fight at the Battle of Narvik , holding out against five times as many British and French troops until finally withdrawing on 28 May . By that time the German offensive in France had progressed to such an extent that the British could no longer afford any commitment in Norway , and the 25 , 000 Allied troops were evacuated from Narvik merely 10 days after their victory . The Norwegian king Haakon VII and part of his government left for England on British cruiser to establish a government - in - exile . Fighting continued in Northern Norway until 10 June , when the Norwegian 6th Division surrendered shortly after Allied forces had been evacuated against the background of looming defeat in France . Among German - occupied territories , this made Norway the country to withstand the German invasion for the longest period of time – approximately two months . Hitler garrisoned Norway with about 300 , 000 troops for the rest of the war . By occupying Norway , Hitler had ensured the protection of Germany ' s supply of iron ore from Sweden and had obtained naval and air bases with which to strike at Britain if necessary . Occupation . German political and military powers . Prior to the invasion , Vidkun Quisling , the leader of Norway ' s fascist party , the " Nasjonal Samling " ( " National Gathering " ) , had tried to persuade Adolf Hitler that he would form a government in support of occupying Germans , although Hitler remained unreceptive to the idea . Hence , on the first day of invasion , Quisling burst into the NRK studios in Oslo and made a nationwide broadcast declaring himself prime minister and ordering all resistance halted at once . This did not please the German authorities , who initially wanted the legitimate government to remain in place . Nevertheless , when it became obvious that the Norwegian parliament would not surrender , the Germans quickly came to recognise Quisling . They demanded that Haakon formally appoint him as prime minister and return his government to Oslo — in effect , giving legal sanction to the invasion . When the German ambassador to Norway , Curt Bräuer , presented his government ' s demands to Haakon , the king let it be known he would abdicate before appointing Quisling prime minister . This prompting the government to unanimously advise him not to appoint any government headed by Quisling . The invaders realised Quisling ' s party couuld not muster any significant support , and quickly pushed him aside . An administrative council led by Ingolf Elster Christensen was therefore established on 15 April to administer those areas which had so far come under German control . The council was abolished on 20 September 1940 , when " Reichskommissar " Josef Terboven took over power by forming his own cabinet . Terboven attempted to negotiate an arrangement with the remaining members of the Norwegian parliament that would give a Nazi cabinet the semblance of legitimacy , but these talks failed . Quisling was consequently re - instituted as head of state on 20 February 1942 , although Terboven retained the sole means to use violence as a political tool , which he did on several occasions ( e . g . by imposing martial law in Trondheim and ordering the destruction of the village of Telavåg ) . Quisling believed that by ensuring economic stability and mediating between the Norwegian civilian society and the German occupiers , his party would gradually win the trust and confidence of the Norwegian population . Membership in the " Nasjonal Samling " did increase slightly in the first few years of the occupation , but never reached significant levels , and eroded towards the end of the war . Military forces such as the " Heer " and " Luftwaffe " remained under direct command of the " Oberkommando der Wehrmacht " in Germany throughout the war , but all other authority was vested in the Reich commissioner . The Nazi authorities made attempts to enact legislation that supported its actions and policies ; it therefore banned all political parties except NS , appointed local leaders top down and forced labour unions and other organizations to accept NS leaders . Although there was much resistance against most of the Nazi government ' s policies , there was considerable cooperation in ensuring economic activity and social welfare programs . Norway was the most heavily fortified country during the war : several hundred thousand German soldiers were stationed in Norway , in a ratio of one German soldier for every eight Norwegians . Most German soldiers considered themselves fortunate to be in Norway , particularly in comparison with those experiencing savage combat duty on the Eastern Front . Approximately 6 , 000 SS troops were garrisoned in Norway during World War II , under the command of " Obergruppenführer " Wilhelm Rediess . Most of these troops were under the authority of the Waffen - SS and the SS and Police Leader hierarchy . SS and Police Leaders for Norway included Hans Hüttig as well as Rediess . In 1944 , the Allgemeine - SS established the 127th SS - Standarte , which was the last command of the General - SS ever created . The powerful battleship was stationed in Norway for most of the war , acting as a " fleet in being " in her own right and tying up huge Allied resources until she was eventually sunk in the last of many attacks . Economic consequences . The economic consequences of the German occupation were severe . Norway lost all its major trading partners the moment it was occupied . Germany became the main trading partner , but could not make up for the lost import and export business . While production capacity largely remained intact , the German authorities confiscated a very large part of the output . This left Norway with only 43 % of its production being freely available . Combined with a general drop in productivity , Norwegians were quickly confronted with scarcity of basic commodities , including food . There was a real risk of famine . Many , if not most , Norwegians started growing their own crops and keeping their own livestock . City parks were divided among inhabitants , who grew potatoes , cabbage , and other hardy vegetables . People kept pigs , rabbits , chicken and other poultry in their houses and outhouses . Fishing and hunting became more widespread . Gray and black markets provided for flow of goods . Norwegians also learned to use " ersatz " products for a wide variety of purposes , ranging from fuel to coffee , tea , and tobacco . Holocaust and deportation of Jews . At the beginning of the occupation , there were at least 2 , 173 Jews in Norway . At least 775 of these were arrested , detained , and / or deported . 742 were murdered in concentration camps , 23 died as a result of extrajudicial execution , murder , and suicide during the war ; bringing the total of Jewish Norwegian dead to at least 765 , comprising 230 complete households . In addition to the few who survived concentration camps , some also survived by fleeing the country , mostly to Sweden , but some also to the United Kingdom . Acceptance and collaboration . Of the Norwegians who supported the " Nasjonal Samling " party , relatively few were active collaborators . Most notorious among these was Henry Oliver Rinnan , the leader of the " Sonderabteilung Lola " ( locally known as " Rinnanbanden " or " the Rinnan group " ) , a group of informants who infiltrated the Norwegian resistance , hence managing to capture and murder many of its members . Furthermore , about 15 , 000 Norwegians volunteered for combat duty on the Nazi side ; of the 6 , 000 sent into action as part of the Germanic SS , most were sent to the Eastern front . Resistance movement . Many Norwegians took part in armed resistance ; others provided support for such activities ; many Norwegians engaged in various forms of civil disobedience ; and many took part in passive resistance efforts . Over time , an organized armed resistance movement , known as Milorg and numbering some 40 , 000 armed men at the end of the war , was formed under a largely unified command , something which greatly facilitated the transfer of power in May 1945 . A distinction was made between the home front ( " Hjemmefronten " ) and the external front ( " Utefronten " ) . The home front consisted of sabotage , raids and clandestine operations ( as was often performed by members of Milorg ) , as well as intelligence gathering ( for which XU was founded ) . Meanwhile the external front included Norway ' s merchant fleet , the Royal Norwegian Navy ( which had evacuated many of its ships to Britain ) , Norwegian squadrons under the British Royal Air Force command and several commando groups operating out of Great Britain and Shetland . One the most successful actions undertaken by the Norwegian resistance was the Norwegian heavy water sabotage , which crippled the German nuclear energy project . Prominent resistance members , among them Max Manus and Gunnar Sønsteby , destroyed several ships and supplies of the " Kriegsmarine " . Radical organizations such as the Osvald Group sabotaged a number of trains and railways . However most organizations opted for passive resistance . Exiled Norwegian forces . About 80 , 000 Norwegian citizens fled the country during the course of the war . Since the Norwegian parliament continued to operate in exile in Britain , many of these exiles voluntarily came to serve in Allied military service , often forming their own distinct Norwegian units in accordance with the Allied Forces Act . By the end of the war these forces consisted of some 28 , 000 enlisted men and women . Navy . In June 1940 , some 13 warships and 5 aircraft of the Royal Norwegian Navy , including their 500 operating personnel , followed the King and parliament to Britain . Throughout the war , some 118 ships had served the Norwegian Navy , of which 58 were in active service by the war ' s end . By this time the Norwegian Navy had continuously and actively served Allied forces since the summer of 1940 , and had suffered the loss of 27 ships and 650 men . Air force . In order to develop and train an Air Force , a training camp known as " Little Norway " was set up near Toronto , Canada , on November 10 , 1940 . However , a unified Royal Norwegian Air Force was only founded as a separate branch of the military of Norway on 10 November 1944 , a date before which it operated in two distinct branches — then known as the Royal Norwegian Navy Air Service and the Norwegian Army Air Service . The Air Force operated four squadrons in support of Allied forces : A number of Norwegian volunteers also served in British RAF units . Combined together , the Norwegian fighter squadrons ( No . 331 and 332 ) and Norwegian fighters operating in RAF service accounted for a total 247 destroyed , 42 assumed destroyed and 142 damaged enemy aircraft . By the war ' s end , the Norwegian Air Force counted a total of 2 , 700 personnel and had suffered a total of 228 losses . Army . The Norwegian Army received the lowest priority of all the exiled Norwegian forces ; its size never exceeded more than 4 , 000 men . Following its last organizational reform in 1942 , the Army consisted of the following units : Allied raids in Norway . Throughout the war , Allied planners remained wary of the strategic significance of Norway . Commando raids were carried out in several locations ; some with the intention of deceiving German commanders as part of Operation Fortitude North , others with the explicit aim of disrupting German military and scientific capabilities , such as sabotaging the German nuclear energy project . Many of these allied raids were achieved with the help of exiled Norwegian forces . Notable military operations in Norway include : Liberation . Lapland War , Soviet advance and retreat of the German army . With the beginning of the German withdrawal from Lapland , the initial German plan was to retain the essential nickel mines around Petsamo in the far North held by the 19th Mountain Corps under General Ferdinand Jodl , but events led to the " Oberkommando der Wehrmacht " ordering the entire 20th Mountain Army out of Finland to take up new defensive positions around Lyngen and Skibotn just to the north of Tromsø — a new operation which came to be called " Operation Nordlicht " ( Operation Northern Light ) . This proved to be a huge logistical undertaking . General Lothar Rendulic , replacing General Eduard Dietl , who had been killed in an air crash , set about evacuating supplies by sea through Petsamo and the Norwegian town of Kirkenes . In early October 1944 , some 53 , 000 men of the German 19th Mountain corps were still some inside Russia along the Litsa River and the neck of the Rybachy Peninsula . The plan was for them to reach Lakselv in Norway , some west , by 15 November . By 7 October however , the combined Soviet 14th Army and Northern fleet , consisting of some 133 , 500 men under Field Marshal Kirill Meretskov , attacked the weakest point of the German line , the junction between the 2nd and 6th Mountain Divisions . A Soviet Naval Brigade also made an amphibious landing to the west of Rybachy , thereby outflanking the Germans . Rendulic , fearing an encirclement of his forces , ordered the 19th Mountain Corps to fall back into Norway . With the Soviets hard on their heels , the Corps reached Kirkenes by 20 October . The German High Command ordered Rendulic to hold the Soviets at bay whilst vital supplies amounting to some could be shipped to safety . Five days later , when the German army prepared to withdraw , only around had been saved . As a result of the German scorched earth policy , Kirkenes was virtually destroyed by the Germans before pulling out : the town was set on fire , port installations and offices were blown up and only a few small houses were left standing . This scene was to be repeated throughout Finnmark , an area larger than Denmark . The Germans were determined to leave nothing of value to the Soviets , as Hitler had ordered Rendulic to leave the area devoid of people , shelter and supplies . Some 43 , 000 people complied with the order to evacuate the region immediately ; those who refused were forced to leave their homes . Some nonetheless stayed behind to await the departure of the Germans : it was estimated that 23 , 000 - 25 , 000 people remained in East - Finnmark by the end of November , they hid in the wilderness until the Germans had left . In Kirkenes , 2000 inhabitants who refused to be taken south sought refuge in the tunnels of an open - cast mine outside the town until liberated by Russian troops some months later : nine babies were born in the tunnels . The Soviets pursued the Germans over the following days , and fighting occurred around the small settlements of Munkelv and Neiden to the west of Kirkenes around 27 October . The German 6th Mountain Division , acting as rear - guard , slowly withdrew up the main road along the coast ( known as " Riksvei 50 " , now called the E6 ) until reaching Tanafjord , some north - west of Kirkenes , which they reached on 6 November . It was to be their last contact with Soviet troops . However , the advancement of the Soviet troops stopped and West - Finnmark and North - Troms became a no man ' s land between the Soviet army and the German army . Here , several thousand people lived in hiding the whole winter 1944 / 45 . These people were called cave people . They lived in caves , in huts made of driftwood and / or turf , under boats turned upside down etc . The risk of being discovered by patrolling German boats was a constant threat during the months waiting for liberation . Exiled Norwegian troops liberate Finnmark . On 25 October 1944 , the order was given for a Norwegian force in Britain to set sail for Murmansk to join the Soviet forces now entering Northern Norway . The envoy was named " Force 138 " and the operation was called " Operation Crofter " . The Norwegian commander , " Oberst " Arne D . Dahl , had under his command : The small force arrived in Murmansk on November 6 and re - embarked on board a Soviet ship to Liinakhamari in Northwestern Soviet Union ( former Northeastern Finland ) , where they thereafter boarded trucks for the final leg of their journey , arriving back on Norwegian soil having spent over four years in exile on November 10 . The Soviet commander , Lieutenant General Sherbakov , made it clear that he wanted the Norwegian " Bergkompani " to take over the forward positions as soon as possible . Volunteers from the local population were hastily formed into " guard companies " armed with Soviet weapons pending the arrival of more troops from either Sweden or Britain . The first convoy arrived from Britain on 7 December and included two Norwegian corvettes ( one of which was later damaged by a mine ) and three minesweepers . It soon became obvious that reconnaissance patrols needed to be sent out to discover what the Germans were up to and to find out if the local population to the West had been evacuated or were still there . The reports came back stating that the Germans were in the process of pulling back from Porsanger but were laying mines and booby - traps along the way , a few people were left here and there and many of the buildings were burnt down . This remained the situation as 1944 slipped into 1945 . The new year would see the Norwegian forces slowly taking back a battered Finnmark , helping the local population in the bitter arctic winter and dealing with occasional German raids from the air , sea and land as well as the ever present danger from mines . Reinforcements arrived from the Norwegian Rikspoliti based in Sweden as well as convoys from Britain . A total of 1 , 442 people and of material were flown in by Dakota from Kallax in Sweden to Finnmark and by April the Norwegian forces stood at over 3 , 000 men . On 26 April the Norwegian command sent out a message that Finnmark was free . When the Germans finally capitulated on 8 May 1945 , the 1st company of the Varanger battalion was positioned along the Finnmark - Troms border to the west of Alta . German capitulation and end of occupation . Towards the end of the war , in March 1945 , Norwegian " Reichskommissar " Josef Terboven had considered plans to make Norway the last bastion of the Third Reich and a last sanctum for German leaders . However , following Adolf Hitler ' s suicide on 30 April , Hitler ' s successor Admiral Karl Dönitz summoned Terboven and General Franz Böhme , Commander - in - Chief of German forces in Norway , to a meeting in Flensburg , where they were ordered to follow the General headquarters ' instructions . On his return to Norway , General Böhme issued a secret directive to his commanders in which he ordered " unconditional military obedience " and " iron discipline " . On 5 May the day that German forces in Denmark surrendered , General Eisenhower dispatched a telegram to resistance headquarters in Norway , which was passed on to General Böhme ; it contained information on how to make contact with Allied General Headquarters . Dönitz dismissed Terboven from his post as " Reichskommissar " on 7 May , transferring his powers to General Böhme . At 21 : 10 on the same day , the German High Command ordered Böhme to follow the capitulation plans , and he made a radio broadcast at 22 : 00 in which he declared that German forces in Norway would obey orders . This led to an immediate and full mobilisation of the underground resistance movement known as Milorg – more than 40 , 000 armed Norwegians were summoned to occupy the Royal Palace , Oslo ' s main police station , as well as other public buildings . A planned Norwegian administration was set up overnight . The following afternoon , on 8 May , an Allied military mission arrived in Oslo to deliver the conditions for capitulation to the Germans , and arranged the surrender , which took effect at midnight . The conditions included the German High Command agreeing to arrest and intern all German and Norwegian Nazi party members listed by the Allies , disarm and intern all SS troops , and send all German forces to designated areas . At this time there were no fewer than 400 , 000 German troops in Norway , which had a population of barely three million . Following the surrender , detachments of regular Norwegian and Allied troops were sent to Norway , which included 13 , 000 Norwegian troops trained in Sweden and 30 , 000 British and American troops . Official representatives of the Norwegian civil authorities followed soon after these military forces , with Crown Prince Olav arriving in Oslo on a British cruiser on 14 May , with a 21 - man delegation of Norwegian government officials headed up by Sverre Støstad and Paul Hartmann , with the remainder of the Norwegian government and the London - based administration following on the troopship " Andes " . Finally , on 7 June , which also happened to be the 40th anniversary of the dissolution of Norway ' s union with Sweden , King Haakon VII and the remaining members of the royal family arrived in Oslo . General Sir Andrew Thorne , Commander - in - Chief of Allied forces in Norway , transferred power to King Haakon that same day . Following the liberation , the Norwegian government - in - exile was replaced by a coalition led by Einar Gerhardsen which governed until the autumn of 1945 when the first postwar general election was held , returning Gerhardsen as prime minister , at the head of a Labour Party government . Norwegian survivors began to emerge from the German concentration camps . By the end of the war 92 , 000 Norwegians were abroad , 46 , 000 of whom were in Sweden . In addition to the German occupiers , there were 141 , 000 foreign nationals in Norway , most of them prisoners of war who had been held by the Germans but who were now liberated . Of these , 84 , 000 were Russians . A total of 10 , 262 Norwegians lost their lives either during the war or while they were imprisoned . Approximately 50 , 000 Norwegians were arrested by the Germans during the occupation . Of these , 9 , 000 were consigned to prison camps outside Norway , including Stutthof concentration camp . Aftermath . Lebensborn and war children . During the five - year occupation , several thousand Norwegian women had children fathered by German soldiers in the " Lebensborn " program . The mothers were ostracised and humiliated after the war both by Norwegian officialdom and the civilian population , and were called names such as " tyskertøser " ( literally " whores of [ the ] Germans " ) . Many of these women were detained at internment camps such as the one on Hovedøya , and some were even deported to Germany . The children of these unions received names like " tyskerunger " ( children of Germans ) or worse yet " naziyngel " ( Nazi spawn ) . The debate on the past treatment of these " krigsbarn " ( war children ) started with a television series in 1981 , but only recently have the offspring of these unions begun to identify themselves . One such child is Anni - Frid Lyngstad , who eventually grew up and achieved fame as a member of the Swedish group Abba . Fritz Moen , the victim of the only known dual miscarriage of justice in Europe , was the child of a Norwegian woman and a German soldier . Refugees . Throughout the war years , a number of Norwegians fled the Nazi regime , mostly across the border to Sweden . These included Norwegian Jews , political activists , and others who had reason to fear for their lives . The Nazis set up border patrols to stop these flights across the very long border , but locals who knew the woods found ways to bypass them . These " border pilots " , and people who hid refugees in their homes , were among those in the resistance movement who took the greatest risks . Swedish authorities accepted the refugees and ensured their safety once they had crossed the border , but did little to facilitate their escape . Refugees were often confined to camps where only their basic needs were met . About 50 , 000 Norwegians fled to Sweden during the war . In addition to the Jews , members of the resistance movement and other people who had more acute reason to fear for their lives , a great many refugees were men of military age wishing to join the Norwegian armed forces abroad . Before the German invasion of Russia , a number of them managed to make their way out of Sweden and travel over Russian territory to Britain , often via India , South Africa or Canada . After Operation Barbarossa the overland route over Russian soil was closed . The rest of the refugees were effectively locked up in Sweden for the duration , except for a small number of officers , pilots or other specialists managing to obtain priority on the occasional plane leaving Sweden for Britain . In the last two years of the war , the Norwegian government in exile in London obtained permission and cooperation from the Swedish authorities to raise military formations on Swedish territory in the form of the so - called " Police troops " recruited from Norwegian refugees . The term " Police " being a cover - up for what in reality was pure military training . These formations , numbering 12 , 000 men organised into battalions and with their own pioneers , signals and artillery by VE - day , were equipped with Swedish weapons and equipment and trained by Norwegian and Swedish officers . A number of the " Police troops " were employed in the liberation of Finnmark in the winter of 1944 / 45 after the area had been evacuated by the Germans . The rest participated in liberation of the rest of Norway after the German surrender in May 1945 . Treason trials . Even before the war ended , there was debate among Norwegians about the fate of traitors and collaborators . A few favored a " night of long knives " with extrajudicial killings of known offenders . However , cooler minds prevailed , and much effort was put into assuring due process trials of accused traitors . In the end , 37 people were executed by Norwegian authorities , 25 Norwegians on the grounds of treason , and 12 Germans on the grounds of crimes against humanity . 28 , 750 were arrested , though most were released for lack of probable cause . In the end , 20 , 000 Norwegians and a smaller number of Germans were given prison sentences . Seventy - seven Norwegians and 18 Germans received life sentences . A number of people were sentenced to pay heavy fines . The trials have been subject to some criticism in later years . It has been pointed out that sentences became more lenient with the passage of time , and that many of the charges were based on the unconstitutional and illegal retroactive application of laws . German prisoners of war . After the war the Norwegian government forced German prisoners of war to clear minefield s . When the clearing ended in September 1946 , 392 of them had been injured and 275 had been killed , meanwhile only two Norwegians and four British mine - clearers had sustained any injuries . Many of the Germans were killed through their guards ' habit of chasing them criss - cross over a cleared field to ensure that no mines remained . The Norwegians ' claim that the German prisoners were Disarmed Enemy Forces circumvented the Geneva Convention relative to the Treatment of Prisoners of War , which forbids the use of prisoners of war for harmful or dangerous labour . Legacy of the occupation . By the end of the war , German occupation had reduced Norway ' s GDP by 45 % – more than any other occupied country . In addition to this came the physical and patrimonial ravages of the war itself . In Finnmark , these were considerably important , as large areas were destroyed as a result of the scorched earth policy that the Germans had pursued during their retreat . Moreover , many towns and settlements were damaged or destroyed by bombing and fighting . Social and cultural transformation . The adversity created as a result of the occupation strengthened and further defined the Norwegian national identity . The history of the resistance movement may have been glorified excessively , but it has also provided Norwegian military and political leaders with durable role models . The shared hardship of the war years also set the stage for social welfare policies of the post - war Norwegian Labour Party governments . It also led to the abandonment of Norway ' s traditional policy of neutrality , formalized when Norway became a founding member of NATO in 1949 . Finally , it led to a broad political and popular commitment to maintain armed forces large enough to realistically defend the country against any likely threat , as well as to keep those armed forces under firm civilian control . One can also see some psychological impact on the political decisions made by the Labour government in the following years . Almost the entire cabinet had been prisoners of war , or had been fighting in the resistance . This experience may have been formative for the actual policy . Surviving Luftwaffe aircraft . The primary Luftwaffe day fighter unit dedicated to serve in the area of Norway , " Jagdgeschwader 5 " ( 5th Fighter Wing ) , was the unit that used more of the surviving World War II German fighter aircraft than any other in the forces of the Axis powers during World War II . The complement of surviving German fighter aircraft that once served with JG 5 comprises some twenty examples of the Messerschmitt Bf 109 , and several examples of the radial - engined versions of the Focke - Wulf Fw 190 . A small number of JG 5 ' s surviving aircraft have been recently restored to flying condition as warbird aircraft with various organizations that fly them in airshow events , and a few others that served with JG 5 are also in the process of being restored to flying condition , early in the 21st century . The lone surviving original example of the Arado Ar 234 " Blitz " turbojet - powered Nazi German reconnaissance bomber , restored and on display in the Smithsonian Institution ' s Udvar - Hazy Center , in 1945 was based in Norway with " Kampfgeschwader 76 " ( 76th Bomber Wing ) .
