With the end of the Winter War, the Allies determined that any occupation of Norway or Sweden would likely do more harm than good, possibly driving the neutral countries into alliance with Germany. However, the new
, took a more aggressive stance than his predecessor and wanted some form of action taken against Germany. Churchill was a strong agitator for attacking and occupying Norway, because he wanted the battles and fighting moved away from Britain and France to avoid devastation of their territory, as in the last war. He saw the way into Germany from the north.
, designed to remove the sanctuary of the Leads and force transport ships into international waters where the
could engage and destroy them. Accompanying this would be Plan R4, an operation where, upon almost certain German counteraction to Operation Wilfred, the Allies would then proceed to occupy

. While the British supported this operation, the French were against it, since they also depended on the Rhine and feared German reprisals on French soil. Because of this delay, Operation Wilfred, originally scheduled for
when the British agreed to perform the Norwegian operations separately from those on the continent.
Main article: Operation Weserübung German plans German invasion The German invasion first started on
3 April 1940, when supply vessels began to head out in advance of the main force. The Allies initiated their plans on the following day, with sixteen Allied submarines ordered to the
Skagerrak and
Kattegat to serve as a screen and advance warning for a German response to Operation Wilfred, which was launched the following day when
Admiral William Whitworth in
HMS Renown set out from
Scapa Flow for the
Vestfjords with twelve destroyers.
On
7 April, bad weather began to develop in the region, blanketing the area with a thick fog and causing rough seas making travel difficult.
Renown's force soon got caught in a heavy snowstorm, and
HMS Glowworm, one of the destroyer escorts, had to drop out of formation to search for a man swept overboard. However, the weather aided the Germans, providing a screen for their forces, and in the early morning they sent out Gruppe 1 and Gruppe 2, who had the largest distance to travel.
Though the weather did make reconnaissance difficult, the two German groups were discovered 170 kilometres (105 mi) south of the Naze (the southernmost part of Norway) slightly after 08:00 by
RAF patrols and reported as one cruiser and six destroyers. A trailing squad of bombers sent out to attack the German ships found them 125 kilometres (78 mi) farther north than they had been before. No damage was done during the attack, but the German groups strength was reassessed as being one battlecruiser, two cruisers and ten destroyers. Because of a strict enforcement of
radio silence, the bombers were not able to report this until 17:30.
On learning of the German movement, the
Admiralty came to the conclusion that the Germans were attempting to break the
blockade that the Allies had placed on Germany and use their fleet to disrupt Atlantic
trade routes. Admiral Sir
Charles Forbes,
Commander-in-Chief of the
British Home Fleet, was notified of this and set out to intercept them at 20:15.
With both sides unaware of the magnitude of the situation, they proceeded as planned. The
Renown arrived at the Vestfjords late that night and maintained position near the entrance while the minelaying destroyers proceeded to their task. Meanwhile, the Germans launched the remainder of their invasion force. The first direct contact between the two sides occurred the next morning without either side's intention.
The
Glowworm, on its way to rejoin the
Renown, happened to come up behind the
Z 11 Bernd von Arnim and then the
Z 18 Hans Lüdemann in the heavy fog around 08:00 on
8 April. Immediately a skirmish broke out and the German destroyers fled, signalling for help. The request was soon answered by the
Admiral Hipper, which quickly crippled the
Glowworm. Being too damaged to outrun the larger German ship, the
Glowworm proceeded to ram it instead. Significant damage was done to
Hipper's starboard, and
Glowworm was destroyed by a close range salvo immediately afterwards. During its fight
Glowworm had broken radio silence and informed the Admiralty of her situation. She was not able to complete her transmission though, and all the Admiralty knew was that the
Glowworm had been confronted by a large German ship, shots were fired, and contact with the destroyer could not be reestablished. In response, the Admiralty ordered the
Renown and its single destroyer escort (the other two had gone to friendly ports for fuel) to abandon its post at the Vestfjords and head to the
Glowworm's last known location. At 10:45, the remaining eight destroyers of the minelaying force were ordered to join as well.
At noon, the Polish submarine
Orzeł confronted and sank the German troop transport ship
Rio de Janeiro in the Skagerrak. In the wreckage it discovered uniformed German soldiers and various military supplies. Though the
Orzeł reported the incident to the Admiralty, they were too concerned by the situation with the
Glowworm and the presumed German breakout to give it much thought and did not pass the information along. Many of the German soldiers from the wreck were rescued by Norwegian fishing boats and on interrogation disclosed that they were assigned to protect Bergen from the Allies. This information was passed on to Oslo where the Norwegian
Parliament,
Stortinget, dismissed it as ignorance on the part of the German soldiers and did not set about any defensive measures other than to alert the coastal guard.
At 14:00, Admiralty received word that aerial reconnaissance had located a group of German ships a considerable distance west-northwest of Trondheim, bearing west. This reinforced the notion that the Germans were indeed intending a break out, and the Home Fleet changed direction from northeast to northwest to again try to intercept. Additionally, Churchill cancelled Plan R4 and ordered the four cruisers carrying the soldiers and their supplies to disembark their cargo and join the Home Fleet. In actuality, the German ships, Gruppe 2, were only performing delaying circling manoeuvres in order to approach their destination of Trondheim at the designated time.
That night, after learning of numerous sightings of German ships south of Norway, Charles Forbes began to doubt the validity of the break out idea, and he ordered the Home Fleet to head south to the Skagerrak. He also ordered
HMS Repulse, along with another cruiser and a few destroyers, to head north and join the
Renown.
At 23:00, as Forbes was just learning of the incident with the Orzeł, Gruppe 5 was approached by the Norwegian patrol vessel
Pol III at the entrance to the
Oslofjord. The
Pol III quickly sent an alarm to the costal batteries on Rauøy (Rauøy island) and opened fire on the
torpedo boat Albatros with its single gun shortly before colliding with it. The
Albatros and two of its companions responded with anti-aircraft fire, killing its captain and setting the ship on fire. Gruppe 5 continued into the Oslofjord and cleared the outer batteries without incident. Several of the smaller German ships then broke off in order to capture the bypassed fortifications along with Horten. This activity did not go unnoticed, and soon reports had reached Oslo, leading to a midnight session of the Storting. At this meeting, the assembly issued orders for a partial mobilization (to be delivered by post) and a statement that British and French ships were not to be fired upon.
At about this time, further north, the
Renown was heading back to Vestfjord after reaching the
Glowworm's last known location and not finding anything. Heavy seas had caused Whitworth to sail more north than normal and had separated him from his destroyers when he encountered the
Scharnhorst and
Gneisenau. The
Renown engaged the two battlecruisers and during the short battle
Gneisenau had its
fire-control system damaged, causing it and
Scharnhorst to flee north.
Renown attempted to pursue, but by 04:00 it lost sight of them in the poor weather.
Movement of fleets In the
Ofotfjord leading to Narvik, the ten German destroyers of Gruppe 1 made their approach. With the
Renown and her escorts earlier diverted to investigate the
Glowworm incident, no British ships stood in their way, and they entered the area unopposed. By the time they had reached the inner area near Narvik, most of the destroyers had peeled off from the main formation to capture the outer batteries of the Ofotfjord, leaving only three to contend with the two old Norwegian coastal battleships standing guard,
Eidsvold and
Norge. Though antiquated, the two coastal defence ships were quite capable of taking on the much more lightly armed and armored destroyers. After a quick parliance with the captain of the
Eidsvold, the German ships opened fire preemptively on the coastal defence ship, sinking it after hitting it with three torpedoes.
Norge entered into the fray shortly after and began to fire on the destroyers, but her marksmen were inexperienced and she did not hit the Germans ships before being sunk by a salvo of torpedoes from the German destroyers.
At Trondheim, Gruppe 2 also faced only minor resistance to their landings. In the
Trondheimsfjord, the
Admiral Hipper engaged the defensive batteries while its destroyers sped past them at 25 knots. A well placed shot by the
Hipper severed the power cables for the searchlights and rendered the guns ineffective. Only one destroyer received a hit during the landing.
At Bergen, the defensive fortifications put up stiffer resistance to Gruppe 3's approach and the light cruiser
Königsberg and the artillery training ship
Bremse were damaged, the former seriously. The lack of working lights reduced the effectiveness of the guns though, and the landing ships were able to dock without much opposition. The fortifications were surrendered soon after, when Luftwaffe units arrived.
The fortifications at Kristiansand put up an even more resolute fight, twice repulsing the landing and damaging the
Karlsruhe, nearly running the cruiser aground. Confusion soon sprung up though when the Norwegians received the order not to fire on British and French ships and the Germans began to use Norwegian codes they had captured at Horten. The Germans used this opportunity to quickly reach the harbour and unload their troops, capturing the town by 11:00.
Gruppe 5 encountered the most serious resistance at the inner defensive fortifications of the Oslofjord, in the vicinity of
Drøbak.
Blücher, leading the group, approached the forts assuming that they would be taken by surprise and not repond in time like many others in the outer fjord. It was not until the cruiser was at point blank range that
fortress Oscarborg opened fire, connecting with every shot. Within a matter of minutes,
Blücher was crippled and burning heavily. The damaged cruiser was soon finished off by a salvo from land-based
torpedo tubes, sinking the ship which carried much of the administrative personnel intended both for the occupation of Norway and also for the headquarters of the army division assigned to seize Oslo. The cruiser
Lützow, also damaged in the attack, was forced to retreat, with Gruppe 5, twelve miles south to
Sonsbukten where it unloaded its troops. This distance delayed the arrival of the main German invasion force for Oslo by over 24 hours, though Oslo would still be captured less than twelve hours later by troops flown into the Fornebu airfield.
Nonetheless, the delay induced by the Norwegian forces gave time for the King, Parliament, and with them the national treasury, to flee to the north and eventually escape to Great Britain. As a result, Norway never surrendered, the Quisling government was rendered illicit, and Norway, with its large merchant marine, remained as an ally in the war, not a conquered territory.
Fornebu was originally supposed to be secured by paratroops an hour before the first troops were flown in, but the initial force became lost in the fog and did not arrive. Regardless, the airfield was not heavily defended and the German soldiers who did arrive captured it promptly. The Norwegian Fighter Wing based on Fornebu resisted with their Gloster Gladiator bi-plane fighters until ammunition ran out and then flew off to whatever secondary airfields available. The ground personnel of the Fighter Wing soon ran out of ammunition for their anti aircraft machine guns as well, in the general confusion and stress to make the fighters ready for action no one had the presence of mind or the time to issue small-arms ammunition for the personal weapons of the ground personell. Resistance at Fornebu came to an end. Norwegian attempts to mount a counter-attack was half-hearted and effectively came to nothing. On learning of this, Oslo itself was declared an
open city and soon fully surrendered.
For Gruppe 6 at Egersund and the paratroops at Stavanger, there was no significant opposition and they quickly captured their targets.
Weserzeit The
Wehrmacht crossed the Danish border around 04:15 on
9 April. In a coordinated operation, German troops disembarked at the docks of Langelinie in the Danish capital,
Copenhagen, and began occupying the city.
German Paratroops also captured the
Aalborg airport. Simultaneously, an ultimatum was presented by the German ambassador to King
Christian X. Reports describing the German plans had been submitted to the government a few days earlier but were ignored. The Danish army was small, ill-prepared and used obsolete equipment but resisted in several parts of the country; most importantly, the Royal Guards located at
Amalienborg Palace in Copenhagen, and forces in the vicinity of
Haderslev in
South Jutland. By 06:30, King Christian X, having consulted with Prime Minister
Thorvald Stauning, decided to capitulate, believing that further resistance would only result in a useless loss of Danish lives. The Danish public was taken completely by surprise by the occupation, and was instructed by the government to cooperate with the German authorities. Germany's
occupation of Denmark was completed on
10 April and lasted until
5 May 1945.
An important part of the Danish commercial navy escaped the occupation, as Arnold Peter Møller, President of the
Mærsk shipping company, on
8 April instructed his 36 ships on the high seas to move to Allied or neutral ports if at all possible.
In a pre-emptive move to prevent a German invasion, on
12 April 1940 British forces occupied the
Faroe Islands, then a Danish
amt (county).
See: British occupation of the Faroe Islands in World War II. Capture of Denmark Soon after this, the German invasions at Trondheim, Bergen, Stavanger, as well as the skirmishes in the Oslofjords became known. Not willing to disperse too thinly due to the unknown location of the two German battlecruisers, the Home Fleet chose to focus on the nearby Bergen and dispatched an attack force. RAF reconnaissance soon reported stronger opposition than anticipated, and this, along with the possibility that the Germans might be controlling the shore defenses, caused them to recall the force and instead use the
aircraft carrier HMS Furious to launch torpedo bombers at the enemy ships. The attack never commenced though, as
Luftwaffe bombers launched an assault of their own against the Home Fleet first. This attack sank the destroyer
HMS Gurkha and then forced the Home Fleet to withdraw north when their
anti-aircraft measures proved ineffective. This German air superiority in the area led the British to decide that all southern regions had to be left to submarines and the RAF, while surface vessels would concentrate on the north.
In addition to the German landings in south and central Norway, the Admiralty was also informed via press reports that a single German destroyer was in Narvik. In response to this they ordered the 2nd Destroyer Flotilla, mostly consisting of ships previously serving as escort destroyers for Operation Wilfred, to engage. This flotilla, under the command of
Captain Bernard Warburton-Lee, had already detached from the
Renown during its pursuit of the
Scharnhorst and
Gneisenau, being ordered to guard the entrance to the Vestfjord. At 16:00 on
9 April, the flotilla sent an officer ashore at
Tranøy fifty miles west of Narvik and learned from the locals that the German force was 4-6 destroyers and a submarine. Warburton-Lee sent these findings back to the Admiralty, concluding with his intention to attack the next day at "dawn, high water", which would give him the element of surprise and protection against any mines. This decision was approved by the Admiralty in a telegram that night.
Early the following morning, Warburton-Lee led his flagship,
HMS Hardy, and four other destroyers into the Ofotfjord. At 04:30, he arrived at Narvik harbour and entered along with
HMS Hunter and
HMS Havock, leaving
HMS Hotspur and
HMS Hostile to guard the entrance and watch the shore batteries. The fog and snow were extremely heavy, allowing Warburton-Lee's force to approach undetected. When they arrived at the harbour itself they found five German destroyers and opened fire, starting the
First Battle of Narvik. Warburton-Lee's ships made three passes on the enemy ships, being joined after the first by
Hotspur and
Hostile, and sank two of the destroyers, disabled one more, and sank six tankers and supply ships. The German commander, Commodore
Friedrich Bonte, lost his life when his flagship
Wilhelm Heidkamp was sunk. Warburton-Lee's flotilla then left the harbour, almost untouched.
At 06:00, the 2nd Destroyer Flotilla was making their way back to the entrance of the Vestfjord when from the
Herjangsfjord behind them three German destroyers emerged, commanded by Commander
Erich Bey, and a few minutes later two more arrived in front of them, surrounding Warburton-Lee's force. The
Hardy was the first ship to be hit and was quickly taken out of action, beached by one of her officers after she was crippled.
Hunter was the next ship put out of commission, coming to a dead halt in the water after several hits.
Hotspur was then hit and received damage to her steering system, causing her to crash into the
Hunter. Several more hits were registered on the pair until
Hotspur was able to reverse out of the wreck. The
Hostile and
Havock meanwhile had raced ahead, but turned about and came back to aid the retreat of the
Hotspur. The German ships having received a few hits and, more importantly, being critically short of fuel, were not able to pursue. As they exited the Ofotfjord, the three British destroyers managed to sink the German supply ship
Rauenfels.
Shortly after the First Battle of Narvik, two more German ships were sunk by British forces. A long range attack by
Fleet Air Arm from their base at
Hatston in the
Orkney Islands was made against Bergen and destroyed the disabled German light cruiser
Königsberg; recorded as the first major warship sunk by aircraft. Additionally, the submarine
HMS Truant sunk the light cruiser
Karlsruhe on the night of
9 April shortly after it had left Kristiansand. The next day,
10 April, the
Furious and the battleship
HMS Warspite joined the Home Fleet and another air attack was made against Trondheim in hopes of sinking the
Admiral Hipper.
Admiral Hipper, however, had already managed to escape through the watch set up outside of the port and was on her way back to Germany when the attack was launched; none of the remaining German destroyers or support ships were hit in the assault. Better luck was had in the south when
HMS Spearfish severely damaged the heavy cruiser
Lützow at midnight on
11 April, putting the German ship out of commission for a year.
With it becoming more evident the German fleet had slipped out of Norwegian waters, Home Fleet continued north to Narvik in the hopes of catching the remaining destroyers.
En route the ships suffered further harassment from German bombers, forcing them to divert course west away from the shoreline. By
12 April, they were in range of Narvik and an aerial attack on Narvik from
Furious was attempted, but the results were disappointing. It was instead decided to send in the battleship
Warspite and a powerful escort force, to be commanded by Whitworth.
On the morning of
13 April, Whitworth's force entered the Vestfjord using the
Warspite's scouting aircraft to guide the way. Aside from locating two of the German destroyers, the scouting aircraft also sunk an enemy submarine, the first such occurrence.
Warspite's destroyers travelled three miles in advance of the battleship and were the first to engage their German counterparts which had come to meet them, thus starting the
Second Battle of Narvik. Though neither side inflicted notable damage, the German ships were running low on ammunition and were gradually pushed back to the harbour. By that afternoon, most attempted to flee up the
Rombaksfjord, the only exception being the
Künne which beached itself as it made for the
Herjangsfjord and was destroyed by
HMS Eskimo. Four British destroyers continued to chase the German ships up through the Rombaksfjord, the
Eskimo soon damaged by the waiting opposition. However, the German situation was hopeless, having run out of fuel and ammunition, and by the time the remaining British ships arrived their crews had abandoned and scuttled their ships. By 18:30 the British ships were making their way out of the now cleared fjord.
Allied response The German invasions for the most part achieved their goal of simultaneous assault and caught the Norwegian forces off guard, a situation not aided by the Norwegian Governments' order for only a partial mobilization. Not all was lost for the Allies though, as the repulsion of German Gruppe 5 in the Oslofjord gave a few additional hours of time which the Norwegians used to evacuate the Royal family and the Norwegian Government to
Hamar. With the government now fugitive,
Vidkun Quisling used the opportunity to take control of a radio broadcasting station and announce a
coup, with himself as the new
Prime Minister of Norway. His first official act, at 19:30 that day, was to cancel the mobilization order.
That evening, the Norwegian Government settled at
Elverum, believing Hamar to be insecure. All German demands were rejected and the
Elverum Authorization was passed should the need for a
government-in-exile arise. However, the bleakness of the situation prompted them to agree to continued negotiations with the Germans, set for the following day. As a precaution
Colonel Otto Ruge, Inspector General of the Norwegian Infantry, set up a roadblock about 110 kilometres (70 mi) north of Oslo, at
Midtskogen, and soon encountered a small detachment of troops, led by the
Air Attaché for the German Embassy, who were racing north in an attempt to settle the matter instantly by capturing
King Haakon VII. A skirmish broke out and the Germans turned back after their air attaché was killed by Norwegian Royal Guards. On
10 April, the final negotiations between the Norwegians and Germans failed after the Norwegian delegates, led by Haakon VII, refused to accept the German demand for recognition of Quisling's new government.
One of the final acts of the Norwegian authorities before dispersement was the promotion of Otto Ruge to the rank of
Major General and appointment to
Commander-in-Chief of the
Norwegian Army, responsible for overseeing the resistance to the German invasion. With the Germans in control of the largest cities, ports and airfields, as well as most of the arms depots and communication networks, repulsing them outright would be impossible. Ruge instead decided that his only chance lay in playing for time, stalling the Germans until reinforcements from the United Kingdom and France could arrive.
On
11 April, after receiving reinforcements in Oslo, General Falkenhorst's offensive began; its goal was to link up Germany's scattered forces before the Norwegian's could effectively mobilize or any major Allied intervention could take place. His first task was to secure the general Oslofjord area, then to use the
196th and
163rd infantry
divisions to establish contact with the forces at Trondheim.
By
14 April, the Norwegian 1st Division, located east of the Oslofjord in the
Østfold, had evacuated into Sweden and the Norwegian 3rd Division, based at Kristiansand, had surrendered. The Norwegian 4th Division, stationed around Bergen, evaded the initial German landings and were soon engaged in slowing the German troops moving eastward from the city; their effort was soon hampered by the fact that the main force of the division had to be transferred to Valdres to shore up for the critical situation on Østlandet. The Norwegian 5th Division at Trondheim had lost almost all of its stores when the invasion began and its commander had decided to remain at
Steinkjer instead of attacking the Germans. The
Norwegian 6th Division was located far to the north, close to the Finnish border and not in contact with any of the German occupied areas.
For General Ruge, only the
Norwegian 2nd Division was available and he thus built his army around the unit. While a surge of volunteers grew the division from 3,000 to roughly 12,000 troops, and Ruge was further aided with 11.1 million
kroner (4.5 million
USD) smuggled to him, it would never be a force capable of direct offensive action against the Germans. Instead, he chose to focus the division at the head of the
Gudbrandsdal and
Østerdalen valleys which led from Oslo to Trondheim. From here he engaged the Germans where the terrain was favourable and used hit-and-run tactics, along with ambushes and selective demolitions to hinder the two German divisions northward movement. These could never hope to completely halt the Germans, who were soon using air support and small tank units to break Norwegian positions. By
20 April, the German forces had managed to advance to Elverum, 305 kilometres (190 mi) south of Trondheim. The constant combat had rendered the Norwegian forces exhausted and critically low on supplies.
Norwegian situation Main article: Allied campaign in Norway Ground campaign The original plans for the campaign in Central Norway called for a three pronged attack against Trondheim by Allied forces while the Norwegians contained the German forces to the south. It was called
Operation Hammer, and would
land Allied troops at Namsos to the north (
Mauriceforce),
Åndalsnes to the south (
Sickleforce), and around Trondheim itself (
Hammerforce). This plan was quickly changed though, as it was felt that a direct assault on Trondheim would be far too risky and therefore only the northern and southern forces would be used.
On
17 April, Mauriceforce, comprised primarily of the
British 146th Infantry Brigade and commanded by Major General
Adrian Carton de Wiart made their initial landings at Namsos. During the trip the force had been transferred to destroyers instead of bulky transport ships due to the narrow waters of the fjord leading to Namsos; in the confusion of the transfer a great deal of their supplies and even the brigade commander were misplaced. Another great problem for Mauriceforce was the lack of
air support, something the Luftwaffe took full advantage off. Shortly after General de Wiart moved his forces out of Namsos, German bombers arrived and destroyed it, leaving the Norwegian without a base. Regardless, de Wiart moved 80 miles inland to Steinkjer where he was able to link up with the Norwegian 5th Division. Constant aerial harassment prevented any kind of offensive from taking place though, and on
21 April Mauriceforce was attacked by the
German 181st Division from Trondheim. The Norwegian was forced to fall back from these assaults, leaving Steinkjer for the Germans.
Sickleforce, consisting primarily of the
British 148th Infantry Brigade and commanded by Major General
Bernard Paget, landed at Åndalsnes on
18 April. From Åndalsnes, the British force traveled via train to the village of
Dombås with the intention of then traveling north to Trondheim; they were instead met there by General Ruge who informed them that the Norwegian forces could not contain the Germans travelling up the valleys for much longer. Knowing that a German breakthrough would both cut off supplies and leave Sickleforce surrounded, Paget diverted his force south to
Lillehammer. They did not stay long though, as the 148th Brigade was soon attacked by Pellengahr's forces and forced to withdraw. As they retreated through the
Tretten Valley, the 148th again came under attack and were effectively eliminated as a fighting unit. By this time, the
British 15th Infantry Brigade had landed in Åndalsnes and had started to move south to relieve the 148th. The British encountered the pursuing German forces at
Kvam, a municipality between Tretten and Dombås, and were pushed back to
Kjorem, where they weathered further heavy assault.
By
28 April, with both groups checked by the Germans, it was decided to withdraw all Allied forces from Central Norway. Sickleforce, with the help of General Ruge, managed to return to Åndalsnes and escape by
2 May at 02:00, only a few hours before the German 196th Division captured the port. Mauriceforce, their convoys delayed by thick fog, were evacuated on
3 May, though two of their rescue ships, the French destroyer
Bison and the British destroyer
Afridi were sunk by
Junkers Ju 87 dive bombers.
The failure of the central campaign is considered one of the direct causes of the
Norway Debate, which resulted in the resignation of British Prime Minister
Neville Chamberlain and the appointment of Winston Churchill to the office.
Campaign in Central Norway Along with the action against Trondheim, a second campaign was launched in the north with the objective of recapturing Narvik. Like the Central campaign, the Narvik expedition also faced numerous obstacles.
One of the first problems faced by the Allies was the fact that the command was not unified, or even truly organized. Naval forces in the area were led by
Admiral of the Fleet William Boyle, 12th Earl of Cork who had been ordered to rid the area of the Germans as soon as possible. In contrast, the commander of the ground forces, Major General
Pierse Mackesy, was ordered not to land his forces in any area strongly held by the Germans and to avoid damaging populated areas. The two met on
15 April to determine the best course of action. Boyle argued for an immediate assault on Narvik and Mackesy countered that such a move would lead to the decimation of his attacking troops. Boyle eventually conceded to Mackesy's viewpoint.
Mackesy's force, codenamed
Rupertforce, consisted of the
24th Guards Brigade as well as French and Polish units. The main force began landing at
Harstad, a small town on the island of
Hinnøya, on
15 April, but because of confusion, bad weather, inadequate facilities, untactically packed transports and constant attacks by German bombers, unloading took well over a week to complete. In the meantime, the Royal Navy had started off on a considerably better note. On
15 April, it captured a German U-boat (U-49) which contained documents detailing the dispositions of all U-boats in the
Norwegian Sea, effectively removing them as a threat.
After the Allied failure in Central Norway, more preparation was given to the northern forces, including two squadrons of carrier-transported fighters operating from
Bardufoss Air Station, one of them consisting of
Hurricanes, the orther of Gloster Gladiators.
By
28 May, the Allies had succeeded in recapturing Narvik from German forces, but the German invasion of France and the Low Countries had immensely altered the overall situation of the war and the importance of Norway was considerably lessened.
Operation Alphabet, the general Allied retreat from Norway, had been approved on
24 May and by
8 June, after destroying rail lines and port facilities, all Allied troops had been evacuated. The Germans had launched
Operation Juno to relieve pressure on the Narvik garrison and, after discovering the evacuation, shifted the mission to a hunt and sunk two British destroyers and the aircraft carrier
HMS Glorious.
Campaign in northern Norway Main article: Occupation of Norway by Nazi Germany Occupation The operation as planned was a decisive success for Germany. Both Denmark and Norway were occupied with relatively light casualties: 3,800 Germans killed and 1,600 wounded. Surprise was almost complete, particularly in Denmark, and only in the Narvik area did the invasion prove problematic. The
Luftwaffe lost about 100 aircraft, or roughly 10% of the force committed.
At sea, however, the invasion proved a significant setback. The Kriegsmarine lost 1 heavy cruiser, 2 light cruisers, 10 destroyers, and 6 submarines, leaving the navy weakened during the summer months when Hitler was pursuing plans for an invasion of Great Britain.
The British also took some damage to their fleet, losing 1 aircraft carrier, 2 cruisers, 7 destroyers, and a submarine, but with their much larger fleet, they could absorb the naval losses to a much greater degree than Germany. Britain also gained use of the Norwegian merchant navy, one of the largest in the world.
The French navy lost 1 large destroyer during the campaign,
The British did achieve a partial success at Narvik. Shipping from the port was stopped for a period of six months, although the Allies had believed it would be out of operation for a year.
The German occupation of Norway was to prove a thorn in the side of the Allies during the next few years. Long-range aircraft based there meant that several squadrons of British fighters had to be kept in the north during the
Battle of Britain, and German commerce raiders used Norway as a staging base to reach the North Atlantic with impunity. After Germany invaded Russia in 1941, air bases in Norway were also used to interdict the Allied
arctic convoys there, inflicting painful losses to shipping.
The occupation of Norway would also come to be a burden for Germany, since the long, exposed coastline provided opportunities for commando raids later in the year. In addition, the country required a sizeable occupation force. This troop commitment peaked with 400,000 men by 1944, troops that could not be put to use during the Allied landings in France that year or on the Russian Front.
