sentences: German U-boat bases in occupied Norway operated between 1940 and 1945, when the "Kriegsmarine" (German navy), converted several naval bases in Norway into submarine bases. Norwegian coastal cities became available to the "Kriegsmarine" after the invasion of Denmark and Norway in April 1940.
 Following the conclusion of the Norwegian Campaign (June 1940), the occupying Germans began to transfer U-boats stationed in Germany to many Norwegian port cities such as Bergen, Narvik, Trondheim, Hammerfest and Kirkenes.
 Initial planning for many U-boat bunkers began in late 1940.
 Starting in 1941, the Todt Organisation began the construction of bunkers in Bergen and Trondheim.
 These bunkers were completed by Weyss & Freytagg AG between 1942 and 1943.
Operation "Weserübung" (] ) was the code name for Germany's assault on Denmark and Norway during the Second World War and the opening operation of the Norwegian Campaign.
 The name comes from the German for Operation Weser-Exercise ("Unternehmen Weserübung"), the Weser being a German river.
The Defence Medal 1940–1945 (Norwegian: Deltagermedaljen 9.
 april 1940 - 8.
 mai 1945/Deltakarmedaljen 9.
 april 1940 - 8.
 mai 1945 ) is the award rewarded to those military and civilian personnel who participated in the fight against the German invasion and occupation of Norway between 1940 and 1945.
The German occupation of Norway began on 9 April 1940 after German forces invaded the neutral Scandinavian country of Norway.
 Conventional armed resistance to the German invasion ended on 10 June 1940 and the Germans then controlled Norway until the capitulation of German forces in Europe on May 8/9, 1945.
 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 Norwegian King and prewar government escaped to London, where they acted as a government in exile.
 This period of military occupation is in Norway referred to as the "war years" or "occupation period".
The First Battle of Dernancourt was fought on 28 March 1918 near Dernancourt, in the Somme department of Hauts-de-France in northern France, during World War I, resulting in a complete defeat of the German assault.
 The Australian 3rd and 4th Divisions had been sent south to help stem the tide of the German Spring Offensive towards Amiens, and with the British 35th Division they held a line west and north of the Ancre river and the area between the Ancre and Somme.
 The main German assault force was the 50th Reserve Division of the XXIII Reserve Corps, which concentrated its attacks on the line between Albert and Dernancourt.
 Other than one small penetration by a German company in the early morning which was quickly resolved, nowhere were the Germans able to break through the British/Australian defences.
 In the following week, the Germans renewed attempts to advance in the sector, culminating in the Second Battle of Dernancourt on 5 April, which was defeated after desperate fighting.
The Norwegian Code (Norwegian: "Norske Lov" , abbreviated NL) is the oldest part of the Norwegian law still in force, partially in force in Norway, Iceland, and the Faroe Islands.
 It was given by Christian V of (Denmark and) Norway on 15 April 1687 and entered into force on 29 September 1688, as the legal code for the Kingdom of Norway including its dependencies (the Faroe Islands, Iceland, and Greenland).
 Norway was a nominally sovereign kingdom, but politically (although not economically) the weaker part in a personal union with Denmark at the time.
 The Norwegian Code was largely based on the Danish Code ("Danske Lov", DL), promulgated in 1683 and itself mostly based on older Danish laws, but the Norwegian Code had some differences from the Danish Code in some areas, such as inheritance law, agricultural law, law relating to hunting, fisheries and trade, and military issues.
 In the 19th and 20th centuries, most of the provisions were gradually repealed as they were replaced by modern laws.
 The code as such remains in force, and it was last amended on 1 January 1993.
 As late as the postwar era, the Supreme Courts of Denmark and Norway interpreted identical provisions from the Danish and Norwegian Code respectively; they came to the opposite conclusions regarding the meaning of identical provisions NL 6-10-2 (in force in Norway until 1985) and DL 6-10-2 (still in force in Denmark).
 The provision is ambiguously worded and regulates compensation for damage caused by livestock and dogs.
 The Supreme Court of Norway ruled on the meaning of this provision in 1954.
Artur von Casimir (4 September 1908 - 15 December 2005) was a German "Oberst" and former bomber pilot who flew for the "Luftwaffe" during World War II.
 Since 2004 he has received a great deal of publicity in Norway.
 One of the Heinkel He 111 he flew was recovered from Jonsvatnet lake near Trondheim in 2004, where it had been submerged since falling through the ice during the spring thaw in April 1940.
 He commanded "Kampfgruppe" 100 during the German invasion of Norway, and led the air raids on Namsos on 20 April 1940 (See Namsos Campaign).
 He assumed the position of "Gruppenkommandeur" over "KGr.
 100" on 16 February 1940.
The German operation for the invasion of Denmark and Norway in April 1940 was code-named "Weserübung", or "Weser Exercise."
 Opposing the invasion were the partially mobilized Norwegian military, and an allied expeditionary force composed of British, French, and Free Polish formations.
 The following list formed the order of battle for this campaign.
Elvegårdsmoen is a military training camp site in the municipality of Narvik in Nordland county, Norway.
 It is located in the inner end of Herjangsfjorden, on the southeast side of the village of Bjerkvik.
 The site was of some importance during the German invasion of Norway in April 1940 and the subsequent Norwegian Campaign.
 The camp was occupied by German forces on 9 April 1940, and it was recaptured by soldiers from the French Foreign Legion during the Battles of Narvik on 13 May 1940.
Friedrich Bonte (19 October 1896 – 10 April 1940) was the German naval officer commanding the destroyer flotilla that transported invasion troops to Narvik during the German invasion of Norway (Operation Weserübung) in April 1940.
