The Continuation War, also known as the Second Soviet-Finnish War, was a conflict fought by Finland and Nazi Germany against the Soviet Union during World War II. It began with a Finnish declaration of war and invasion on 25 June 1941 and ended on 19 September 1944 with the Moscow Armistice. The Soviet Union and Finland had previously fought the Winter War from 1939 to 1940, which ended with the Soviet failure to conquer Finland and the Moscow Peace Treaty. Numerous reasons have been proposed for the Finnish decision to invade, with regaining territory lost during the Winter War regarded as the most common. Other justifications for the conflict include Finnish President Risto Ryti's vision of a Greater Finland and Commander-in-Chief Carl Gustaf Emil Mannerheim's desire to annex East Karelia.
The Winter War was a war between the Soviet Union and Finland. It 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 its organization.
The European theatre of World War II was one of the two main theatres of combat during World War II. It saw heavy fighting across Europe for almost six years, starting with Germany's invasion of Poland on 1 September 1939 and ending with the Western Allies conquering most of Western Europe, the Soviet Union conquering most of Eastern Europe including the German capital Berlin, and Germany's unconditional surrender on 8 May 1945 although fighting continued elsewhere in Europe until 25 May. On 5 June 1945, the Berlin Declaration proclaiming the unconditional surrender of Germany to the four victorious powers was signed. The Allied powers fought the Axis powers on two major fronts, but there were other fronts varying in scale from the Italian campaign, to the Polish Campaign, as well as in a strategic bombing offensive and in the adjoining Mediterranean and Middle East theatre.
Detached Battalion 4 was a special forces unit of the Finnish Army during the Continuation War and Lapland War, serving from July 1943 to November 1944. The battalion was founded under the Intelligence Division of Defence Command from the already operational long-range reconnaissance patrol detachments created during the Interim Peace.
The Eastern Front or the Second Russian Front was a theatre of World War II fought between the European Axis powers and Allies, including the Soviet Union (USSR) and Poland. It encompassed Central Europe, Eastern Europe, Northeast Europe (Baltics), and Southeast Europe (Balkans), and lasted from 22 June 1941 to 9 May 1945. Of the estimated 70–85 million deaths attributed to World War II, around 30 million occurred on the Eastern Front, including 9 million children. The Eastern Front was decisive in determining the outcome in the European theatre of operations in World War II, eventually serving as the main reason for the defeat of Nazi Germany and the Axis nations. It is noted by historian Geoffrey Roberts that "More than 80 percent of all combat during the Second World War took place on the Eastern Front".
Finland participated in the Second World War initially in a defensive war against the Soviet Union, followed by another, this time offensive, war against the Soviet Union acting in concert with Nazi Germany and then finally fighting alongside the Allies against Germany.
Cold-weather warfare, also known as arctic warfare or winter warfare, encompasses military operations affected by snow, ice, thawing conditions, or cold, both on land and at sea, as well as the strategies and tactics used by military forces in these situations and environments.
The Baltic Sea campaigns were conducted by Axis and Allied naval forces in the Baltic Sea, the Gulf of Bothnia, the Gulf of Finland and the connected lakes Ladoga and Onega on the Eastern Front of World War II. After early fighting between Polish and German forces, the main combatants were the Kriegsmarine and the Soviet Navy, with Finland supporting the Germans until 1944 and the Soviets thereafter. The Swedish Navy and merchant fleet played important roles, and the British Royal Navy planned Operation Catherine for control of the Baltic Sea and its exit choke point into the North Sea.
The military history of Finland consists of hundreds of years of armed actions in the territory encompassing modern Finland.
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 Battle of Ilomantsi was a part of the Svir–Petrozavodsk Offensive of the Continuation War (1941–1944). It was fought from 26 July to 13 August 1944, between Finland and the Soviet Union in an area roughly 40 kilometers wide and 30 kilometers deep, near the Finnish-Soviet border, close to the Finnish village of Ilomantsi, in North Karelia. The battle ended with a Finnish victory—the last major Soviet attack against Finland was stopped here.
Major General Erkki Johannes Raappana was the commander of the 14th Division of the Finnish Army during the Second World War.
The German Army was the land forces component of the Wehrmacht, the regular armed forces of Nazi Germany, from 1935 until it effectively ceased to exist in 1945 and then was formally dissolved in August 1946. During World War II, a total of about 13.6 million soldiers served in the German Army. Army personnel were made up of volunteers and conscripts.
In Soviet historiography, Stalin's ten blows were the ten successful strategic offensives in Europe conducted by the Red Army in 1944 during World War II. The Soviet offensives drove the Axis forces from Soviet territory and precipitated Nazi Germany's collapse.
During World War II, the Lapland War saw fighting between Finland and Nazi Germany – effectively from September to November 1944 – in Finland's northernmost region, Lapland. Though the Finns and the Germans had been fighting together against the Soviet Union since 1941 during the Continuation War (1941–1944), peace negotiations between the Finnish government and the Allies of World War II had been conducted intermittently during 1943–1944, but no agreement had been reached. The Moscow Armistice, signed on 19 September 1944, demanded that Finland break diplomatic ties with Germany and expel or disarm any German soldiers remaining in Finland.
The Liberation of Finnmark was an Allied military operation lasting from 23 October 1944 until 26 April 1945, in which Soviet and Norwegian forces wrested away control of Finnmark, the northernmost county of Norway, from Germany. It began with a Soviet offensive that liberated Kirkenes.
The II Corps was a unit of the Finnish Army during the Continuation War. During the war the corps participated in combat first northwest of Lake Ladoga and on the Karelian Isthmus before moving to the Povenets–Lake Segozero region by late 1941. During the Soviet offensive of 1944, the corps conducted a fighting retreat to the region of Ilomantsi, with parts of its forces participating in the subsequent Battle of Ilomantsi.
The VI Corps was a corps of the Finnish Army during the Continuation War of 1941 to 1944, where the Finnish Army fought alongside Germans against the Soviet Union. The unit was formed during a reorganization of other Finnish army corps on 29 June 1941, prior to the start of Finnish offensive operations on the night of 9–10 July.
