context_page_description: The North Russia intervention, also known as the Northern Russian expedition, the Archangel campaign, and the Murman deployment, was part of the Allied intervention in the Russian Civil War after the October Revolution. The intervention brought about the involvement of foreign troops in the Russian Civil War on the side of the White movement. The movement was ultimately defeated, while the Allied forces withdrew from Northern Russia after fighting a number of defensive actions against the Bolsheviks, such as the Battle of Bolshie Ozerki. The campaign lasted from March 1918, during the final months of World War I, to October 1919.
context_section_description: In March 1917, after the abdication of Russian Tsar Nicholas II and the formation of a provisional democratic government in Russia, the U.S. entered World War I. The U.S. government declared war on the German Empire in April (and later upon Austria-Hungary) after learning of the former's attempt to persuade Mexico to join the Central Powers. The Russian Provisional Government, led by Alexander Kerensky, pledged to continue fighting Imperial Germany on the Eastern Front. In return, the U.S. began providing economic and technical support to the Russian provisional government, so they could carry out their military pledge.
  The Russian offensive of 18 June 1917 was crushed by a German counteroffensive. The Russian Army was plagued by mutinies and desertions. Allied war materiel still in transit quickly began piling up in warehouses at Arkhangelsk (Archangel) and the ice-free port of Murmansk. Anxious to keep Russia in the war, the Royal Navy established the British North Russia Squadron under Admiral Kemp.
  The Bolsheviks, led by Vladimir Lenin, came to power in October 1917 and established the Russian Soviet Federative Socialist Republic. Five months later, they signed the Treaty of Brest-Litovsk with Germany, which formally ended the war on the Eastern Front. This allowed the German army to begin redeploying troops to the Western Front, where the depleted British and French armies had not yet been bolstered by the American Expeditionary Force.
  Coincidental with the Treaty, Lenin personally pledged that if the Czechoslovak Legion would stay neutral and leave Russia, they would enjoy safe passage through Siberia on their way to join the Allied forces on the Western Front. However, as the 50,000 members of the Legion made their way along the Trans-Siberian Railroad to Vladivostok, only half had arrived before the agreement broke down and fighting with the Bolsheviks ensued in May 1918. Also worrisome to the Allied Powers was the fact that in April 1918, a division of German troops had landed in Finland, creating fears they might try to capture the Murmansk–Petrograd railroad, the strategic port of Murmansk and possibly even the city of Arkhangelsk. It was also feared that large military stores at Archangelsk might fall into unfriendly hands.
  Faced with these events, the leaders of the British and French governments decided the western Allied Powers needed to begin a military intervention in North Russia. They had three objectives: they hoped to prevent the Allied war materiel stockpiles in Arkhangelsk from falling into German or Bolshevik hands; to mount an offensive to rescue the Czechoslovak Legion, which was stranded along the Trans-Siberian Railroad and resurrect the Eastern Front; and by defeating the Bolshevik army with the assistance of the Czechoslovak Legion, to expand anti-communist forces drawn from the local citizenry.
  Severely short of troops to spare, the British and French requested that US President Woodrow Wilson provide U.S. troops for what was to be called the North Russia Campaign, or the Allied Intervention in North Russia. In July 1918, against the advice of the US War Department, Wilson agreed to a limited participation in the campaign by a contingent of U.S. Army soldiers of the 339th Infantry Regiment, that was hastily organized into the American North Russia Expeditionary Force, which came to be nicknamed the Polar Bear Expedition.  Under his Aide Memoire, Wilson set the guidelines for American intervention by saying the purpose of American troops in Russia was "to guard military stores which may subsequently be needed by Russian forces and to render such aid as may be acceptable to the Russians in the organization of their own self-defense."
