The Continuation War, also known as the Second Soviet-Finnish War, was a conflict fought by Finland and Nazi Germany against the Soviet Union from 1941 to 1944, as part of World War II. In Soviet historiography, the war was called the Finnish Front of the Great Patriotic War. Germany regarded its operations in the region as part of its overall war efforts on the Eastern Front and provided Finland with critical material support and military assistance, including economic aid.
The Winter War, also known as the First Soviet-Finnish War, was a war between the Soviet Union and Finland. The war began with a Soviet invasion of Finland on 30 November 1939, three months after the outbreak of World War II, and ended three and a half months later with the Moscow Peace Treaty on 13 March 1940. Despite superior military strength, especially in tanks and aircraft, the Soviet Union suffered severe losses and initially made little headway. The League of Nations deemed the attack illegal and expelled the Soviet Union from the organisation.
The Mannerheim Line was a defensive fortification line on the Karelian Isthmus built by Finland against the Soviet Union. While this was never an officially designated name, during the Winter War it became known as the Mannerheim Line, after Finnish Army's then commander-in-chief Field Marshal Baron Carl Gustaf Emil Mannerheim. The line was constructed in two phases: 1920–1924 and 1932–1939. By November 1939, when the Winter War began, the line was by no means complete.
The Eastern Front of World War II was a theatre of conflict between the European Axis powers against the Soviet Union (USSR), Poland and other Allies, which encompassed Central Europe, Eastern Europe, Northeast Europe (Baltics), and Southeast Europe (Balkans) from 22 June 1941 to 9 May 1945. It was known as the Great Patriotic War in the Soviet Union – and still is in some of its successor states, while almost everywhere else it has been called the Eastern Front. In present-day German and Ukrainian historiography the name German-Soviet War is typically used.
German–Soviet Union relations date to the aftermath of the First World War. The Treaty of Brest-Litovsk, dictated by Germany ended hostilities between Russia and Germany; it was signed on March 3, 1918. A few months later, the German ambassador to Moscow, Wilhelm von Mirbach, was shot dead by Russian Left Socialist-Revolutionaries in an attempt to incite a new war between Russia and Germany. The entire Soviet embassy under Adolph Joffe was deported from Germany on November 6, 1918, for their active support of the German Revolution. Karl Radek also illegally supported communist subversive activities in Weimar Germany in 1919.
Finland participated in the Second World War initially in a defensive war against the Soviet Union, followed by another battle against the Soviet Union acting in concert with Nazi Germany and then finally fighting alongside the Allies against Germany.
The so-called Molotov Line comprised a system of border fortified regions built in the Soviet Union in the years 1940–1941 along its new western borders. These border revisions resulted of the occupation of the Baltic States, Eastern Poland and Bessarabia in 1940.
The Vyborg–Petrozavodsk offensive or Karelian offensive was a strategic operation by the Soviet Leningrad and Karelian Fronts against Finland on the Karelian Isthmus and East Karelia fronts of the Continuation War, on the Eastern Front of World War II. The Soviet forces captured East Karelia and Vyborg/Viipuri. After that, however, the fighting reached a stalemate.
The Soviet invasion of Poland was a military operation by the Soviet Union without a formal declaration of war. On 17 September 1939, the Soviet Union invaded Poland from the east, 16 days after Nazi Germany invaded Poland from the west. Subsequent military operations lasted for the following 20 days and ended on 6 October 1939 with the two-way division and annexation of the entire territory of the Second Polish Republic by Nazi Germany and the Soviet Union. This division is sometimes called the Fourth Partition of Poland. The Soviet invasion of Poland was indirectly indicated in the "secret protocol" of the Molotov–Ribbentrop Pact signed on 23 August 1939, which divided Poland into "spheres of influence" of the two powers. German and Soviet cooperation in the invasion of Poland has been described as co-belligerence.
Czechoslovakia built a system of border fortifications as well as some fortified defensive lines inland, from 1935 to 1938 as a defensive countermeasure against the rising threat of Nazi Germany. The objective of the fortifications was to prevent the taking of key areas by an enemy—not only Germany but also Hungary and Poland—by means of a sudden attack before the mobilization of the Czechoslovak Army could be completed, and to enable effective defense until allies—Britain and France, and possibly the Soviet Union—could help.
The 22nd Karelian Fortified Region is a 60 km wide Soviet defensive fortified district to the north of Leningrad that was built in 1928–1932, 1938–1939, 1941–1944 and 1950–1965 in the Soviet part of the Karelian Isthmus amongst other fortified areas constructed around that time in order to defend the western borders of the Soviet Union. The KaUR spans the old Finno-Russian border from Valkeasaari near the northern shore of the Gulf of Finland through Lempaala to Nizhniye Nikulyasy Bay on the western shore of Lake Ladoga.
The Iron Curtain was the political boundary dividing Europe into two separate areas from the end of World War II in 1945 until the end of the Cold War in 1991. The term symbolizes the efforts by the Soviet Union (USSR) to block itself and its satellite states from open contact with the West, its allies and neutral states. On the east side of the Iron Curtain were the countries that were connected to or influenced by the Soviet Union, while on the west side were the countries that were NATO members, or connected to or influenced by the United States; or nominally neutral. Separate international economic and military alliances were developed on each side of the Iron Curtain. It later became a term for the 7,000-kilometre-long (4,300 mi) physical barrier of fences, walls, minefields, and watchtowers that divided the "east" and "west". The Berlin Wall was also part of this physical barrier.
After the Munich Agreement, the Soviet Union pursued a rapprochement with Nazi Germany. On 23 August 1939 the Soviet Union signed a non-aggression pact with Germany which included a secret protocol that divided Eastern Europe into German and Soviet "spheres of influence", anticipating potential "territorial and political rearrangements" of these countries. Germany invaded Poland on 1 September 1939, starting World War II. The Soviets invaded eastern Poland on 17 September. Following the Winter War with Finland, the Soviets were ceded territories by Finland. This was followed by annexations of the Baltic states and parts of Romania.
The Soviet occupation of the Baltic states covers the period from the Soviet–Baltic mutual assistance pacts in 1939, to their invasion and annexation in 1940, to the mass deportations of 1941.
The Swiss National Redoubt is a defensive plan developed by the Swiss government beginning in the 1880s to respond to foreign invasion. In the opening years of the Second World War the plan was expanded and refined to deal with a potential German invasion. The term "National Redoubt" primarily refers to the fortifications begun in the 1880s that secured the mountainous central part of Switzerland, providing a defended refuge for a retreating Swiss Army.
The Kiev Fortified Region is a fortified district in the Kyiv area, a complex of defensive structures, consisting of permanent and field fortifications and engineering obstacles. It was built in the period from 1929 to 1941 for the protection of the old border of the USSR. The total length of the fortified region is about 85 km between the flanks, which are anchored on the river Dnieper, and the depth of the defensive zone ranges from 1 to 6 km.
A fortified district or fortified region in the military terminology of the Soviet Union, is a territory within which a complex system of defense fortifications was engineered.
Ivan Iosifovich Proskurov was a Soviet pilot and recipient of the title Hero of the Soviet Union, best known as the chief of military intelligence who tried in vain to warn Joseph Stalin that the Red Army was ill-prepared to defend the USSR against a German invasion - unwelcome advice which apparently cost him his life.
The 386th Rifle Division was raised in 1941 as an infantry division of the Red Army, and served twice during the Great Patriotic War in that role. The division followed a very similar combat path to that of the 388th Rifle Division in both of its formations. It was first formed on August 19 in the Transcaucasus Military District. In late December it was shipped from the Black Sea ports to Sevastopol, which was under siege by the German 11th Army. The division arrived just as the second Axis assault on the fortress was ending and did not see any heavy fighting until the final offensive, Operation Störfang, began on June 2, 1942. On June 18 it came under attack from the Romanian Mountain Corps and put up a stiff fight but rapidly lost strength and cohesion before falling back towards the port in the last days of the month; it was officially disbanded just days before the final Axis victory. In the buildup to the Soviet invasion of Manchuria a new 386th was formed in the Far Eastern Front in late 1944. The new division fought with enough distinction that it was awarded the Order of the Red Banner, and continued to serve briefly into the postwar period.
