The Winter War: A brief examination

By Jarmo Markkanen

Well, I finally got the more detailed description about the Winter War finished. In this version, some of the previously described topics (like the motti-tactics) have been left out. the main body of this writing was built by using several Finnish encyclopedias and if there were some controversialities (and there often were!) I used my books being written about the Winter War only (like Esa Anttala's "Talvisota") to find out the 'truth'.

The Winter War:

Reasons for the war:
October 23rd -39 Soviet Union and Germany signed a non-aggression pact. It was also an agreement of dividing the Baltic area into their districts of interest. Finland was a part of Soviet Union's district. During fall of 1939 Soviet Union demanded several times Finland to give away some land areas in order to improve its ability to defense Leningrad. Those land areas were part of Karelian Isthmus and some islands in the Finnish Gulf, including Suursaari and Koivisto. Soviets also wanted to establish a military base to cape of Hanko and a part of of Kalastajasaarento island lying on the coast of Barents Sea.
Finland's government refused Soviet attempts.

The war starts:
In the end of November -39 Soviet Union (SU) accused Finnish gunnery shooting over the border in Mainila, a village in Karelian Isthmus and started "defensive measures". Later it has been found out that those "Mainila shots" were shot by Soviets themselves. Nov 30th Soviet troops crossed the border and Soviet bombers made several attacks
against Helsinki and other civilian targets.

Dec 1st SU established so called Terijoki government to be the only legal government of Finland it wanted to negotiate with. Terijoki government consisted of Finnish communist emigrants living in Moscow.
The reasons for this were to find a reason to refuse the negotiation attempts made by the actual Finnish government. Second, it was also an attempt to shake the unstable political situation in Finland. At that time Finns were deeply divided in left- and right-wing supporters. But it didn't work: political disagreements were put aside and the whole nation rose against the enemy intruder.

SU had at the start 22 divisions, about half a million soldiers, about 2000 tanksand about 1000 airplanes. They were led at that time by the 2nd class commander of the Leningrad military district, K.A. Meretskov. Finnish troops, consisting of nine divisions and few brigades (about 350,000 men), had only few tanks and about 110 airplanes.They were led by the Warmarshal C.G.E. Mannerheim.

In December -39, Soviets attempted a breakthrough in Karelian Isthmus but were hit back in battles of Taipale and Summa. The Soviet troops were taken back to their positions and to wait for reinforcements.
Along the northern front, Finnish soldiers faced much stronger Soviet forces than expected. That caused re-placing of the Finnish reserves all along the long border. Strong Soviet attacks in Tolvajarvi were stopped by Finnish reserve troops at the same time. In Suomussalmi the Finnish 9th division, led by H. Siilasvuo, destroyed two Sovietdivisions. Soviet troops managed to get close to Kemijarvi, but were fought back. The Soviet 14th army took Petsamo, but was stopped in
Nautsi.

In the beginning of January -40, the Supreme Command of the Soviet troops could see that it had suffered a strategic loss against Finland. They established a North-Western Front, led by 1st classCommander S.K. Timosenko. It consisted of about 45 divisions (about 1,000,000 men) six tank brigades and lots of gunnery. 25 of the divisions and all of the tank brigades were moved to Karelian Isthmus. The rest of the divisions were placed along the front north from lake Laatokka and ordered to save the Soviet divisions trapped in several mottis. For comparison, Finland had 7 divisions (about 150,000 men) in Karelian Isthmus and 91,000 men along the front between lake Laatokka and the Arctic Ocean. These numbers of men at arms don't tell the whole truth: the Soviet army had an overwhelming advantage against Finns what comes to the armament while Finnish troops had only few guns and tanks.

The Soviet major attack:
The Soviet major attack started in the beginning of February -40. The emphasis was in the Karelian Isthmus, in Summa, where 9 Soviet divisions and 5 tank brigades supported with 1,200 guns attacked against the Finnish 3rd division in the Mannerheim-line. Finnish troops kept their positions for three days but were then ordered to retreat to the next defense line. The battle in Summa was one of the main battles in the Winter War. The withdraw of the Finnish troops from their best built defensive line forced Finns to continue defending from temporarily and not so well-built bases. The Soviet divisions continued to attack against Finnish lines. After ten days of heavy fighting, Finns had to withdraw from their positions and move to the last defense line. The situation got worse when 6 Soviet divisions attacked over the Viipuri Bay and tried to surround the Finnish troops defending the city of Viipuri. However, Finns managed to keep their positions in Karelian Isthmus till the end of war.

North from lake Laatokka, Soviet forces attempted to open the ten mottis, where Finns had closed in the Soviet 168th and 18th divisions and the 34th tank brigade. Even when 10 more Soviet divisions were moved into these battles, the Finnish 4th Army Group managed to destroy 7 of those mottis while the rest were guarded till the end of the war. This prevented Soviets taking the city of Sortavala and moving south to the back of the Finnish troops in Isthmus. In the Lapland front, Soviet attacks were stopped.

"The miracle of the Winter War":
Well, if one place from somewhere along the front should be pointed to say "this is the where the miracle took its place", it must be the Kollaa-river, north-east from Sortavala. In the beginning of the war, the Soviet 56th division advanced close to the village of Loimola. The Finnish 12th division, led by colonel A.Svensson, managed to stop them at the Kollaa-river, 10 km east from Loimala. In the heavy fights, the 12th division kept its positions to the end of the Winter War, even Soviet moved four more divisions to the area. Soviet divisions suffered heavy losses in their attacks. By keeping their positions, Finnish troops were able to continue their fights along this part of the front. "Kollaa kestaa /Kollaa stands firm", a Finnish slogan was born then.

About the naval warfare during the Winter War:
Finland evacuated its outer islands in the Finnish Gulf right after the war started. The southern coast of Finland is surrounded by a dense section of small islands. Hence making the narrow sea routes to the continent easy to be defended. This fact with the very cold winter made the invasion over the Finnish Gulf impossible to the
Soviets. Soviet ships interfered the traffic of the Finnish trading ships till the end of January when Soviets took their ships back from the trading routes.

Aerial warfare:
Right after the war started, Soviet bombers attacked against several civilian targets all along Finland. The few Finnish interceptors were unable to prevent those bombings. During January -40 Soviet bombers concentrated their activities against railways and harbours. During the Soviet major attack the planes attacked against the Finnish frontline and the supply centers behind the line. Finns counted 7,000 Soviet planes flying inside the Finnish borders in January -40, 17,000 in February and 6,000 in March. Almost 100,000 bombs were dropped in Finland. Soviet air forces lost 747 planes (confirmed), Finland lost 61 planes and 44 pilots.

The end of the Winter War:
In the beginning, Soviet Union refused to negotiate with any other government than the Terijoki Government. When the Red Army's advance was much slower than expected, they finally agreed to negotiate with the legal Finnish government. The negotiations started in the beginning of February -40. Soviet Union's demands were whole Karelia, including the Isthmus and the land areas north-east from Laatokka, plus a military base to the cape of Hanko. Because of these unexpected large demands Finland asked military assist from Sweden and a passage for the possible army forces from Western Allied countries. Sweden denied both of them (Swedish volunteers were allowed to enter the war, unofficially of course). When Allied countries were not directly promising any help either, the Finnish government sent a delegation to Moscow to negotiate for peace. Finland was still planning to receive help from the Allies, but the time was running out from the Finnish forces and the Finnish negotiators finally signed the peace in Moscow May 12th -40. The war ended next morning. Finland lost the whole south-east part of the country, land areas in Salla-Kuusamo, the outer islands in Finnish Gulf, Kalastajasaarento and Srednisaarento lying in the Arctic Ocean, plus Soviet rented the cape of Hanko for military base. Finland lost more than 10% of its land, more than
400,000 Finns living there.

Losses:
Finland lost 23,157 men dead and about 45,000 men wounded where 10,000 becoming invalid for the rest of their life. Finland estimated Soviet losses being about 200,000 men, where Soviet claimed having lost only 48,000 men. Later Finnish estimations have proved out to be very close to the truth.
