Continuation War

The Continuation War was a major military conflict during World War II.

It involved Finland and Nazi Germany fighting against the Soviet Union. Some historians call it the Second Soviet-Finnish War. The conflict began on 25 June 1941. It lasted until 19 September 1944. The war was shaped by previous tensions and shifting alliances in Europe. It significantly altered the borders and political landscape of Northern Europe.

The roots of the war lie in the Winter War of 1939 to 1940.

During that earlier conflict, the Soviet Union invaded Finland. The war ended with the Moscow Peace Treaty. Under this treaty, Finland ceded 9% of its national territory. It also lost 13% of its economic capacity. This meant 420,000 evacuees had to find new homes. These losses created a strong desire in Finland to regain lost land.

Several goals drove the Finnish decision to restart the conflict. Many people wanted to reclaim the territory lost in 1940. President Risto Ryti held a vision of a "Greater Finland."

Commander-in-Chief Carl Gustaf Emil Mannerheim also wanted to annex East Karelia. These political goals coincided with a change in German policy. Originally, Germany had refused to sell arms to Finland. However, Germany soon planned to invade the Soviet Union. This changed the relationship between the two nations.

Events moved rapidly in the summer of 1941.

On 22 June, Germany invaded the Soviet Union. Three days later, the Soviet Union conducted air raids on Finnish cities. This prompted Finland to declare war on 25 June 1941.

Finnish and German troops began offensive operations together. By September 1941, Finland had regained its post-Winter War concessions in Karelia.

The Finnish Army then moved further into East Karelia.

The war involved several distinct fronts and military objectives. In the north, joint German-Finnish forces attempted to reach Murmansk.

They also tried to cut the Kirov, or Murmansk, Railway. These attempts did not succeed. In the center, Finnish forces participated in the siege of Leningrad. They cut northern supply routes and remained in position until 1944. This period was marked by long periods of stationary warfare and defensive positions.

In 1944, the momentum of the war shifted significantly. The Soviet Union launched the Vyborg–Petrozavodsk offensive in June and August. This massive movement drove Finnish forces out of most regained territories. However, the Finnish Army managed to halt the Soviet offensive in August 1944.

This allowed for a ceasefire to be negotiated. The fighting finally ceased with the signing of the Moscow Armistice in September 1944.

This agreement ended the active hostilities between the two nations.

The terms of the Moscow Armistice were quite strict for Finland. Finland had to restore its borders to the 1940 levels. It also had to cede the Petsamo region to the Soviet Union.

Additionally, Finland had to lease the Porkkala Peninsula to the Soviets. The agreement required Finland to pay war reparations. Finland also had to acknowledge it was a German ally. Finally, Finland had to expel all German troops from its territory. This requirement led directly to a new conflict called the Lapland War.

The Continuation War connects to the broader geopolitical struggles of the era. It was part of the larger struggle for influence in the Baltic region. The Soviet Union sought to create a "buffer zone" for security. Western historians often view these actions through a different lens. The war demonstrated how small nations were affected by the actions of great powers. It also showed how quickly alliances can change during global conflicts.
