The
Norwegian Campaign (9 April to 10 June 1940) was a
Second World War campaign fought in
Norway between the
Allies and
Germany after the latter's
invasion of the country. In April, the
United Kingdom and
France came to Norway's aid with an expeditionary force. Despite moderate success in the northern parts of Norway, Germany's
invasion of France in May eventually compelled the Allies to withdraw and the Norwegian government to seek exile in London. The campaign ended with the occupation of Norway by Germany, and the continued fighting of
exiled Norwegian forces from abroad. The 62 days of fighting made Norway the nation that withstood a German invasion for the second longest period of time, after the
Soviet Union.
