One of the most daring and unique Finnish operations during the period of trench warfare was the capture of Suursaari Island in the Gulf of Finland, 43km south of Kotka and 56km north of the Estonian coast. Due to its location, this 11km-long island had great strategic significance. Artillery stationed there could control most of the sea lanes to Leningrad. In 1939, the Soviet Union repeatedly approached Finland to see if it could annex Suursaari and the other outlying islands. When these requests were refused, the Red Army took the islands by force during the Winter War.
During the Summer War, the Finnish and German high commands agreed that Suursaari and other outlying islands had to be wrested back from Soviet hands. When supported from these islands, the Soviet Navy was able to disrupt all naval traffic to Kotka harbour, and extend their range of operations deeper into the Baltic Sea. Conversely, if Finland were to hold the islands, it would enable the Germans to bottle up the Soviet Navy into a small corner of the Gulf of Finland. In addition, the establishment of air observation bases on the archipelago could provide early warnings that would considerably increase tactical timeframes for all aerial operations.
Finnish headquarters agreed on a joint operation with the Wehrmacht high command to capture Suursaari and the neighbouring islands. They decided that the best time for the attack would be during midwinter across the frozen Gulf of Finland. Attacking while the sea lanes were still open was considered too risky, as the enemy would be able to ship reinforcements and heavy equipment rapidly to the islands. Once it became apparent that the Germans could not spare the troops needed for the operation, Mannerheim decided that the Finns would carry out the audacious plan themselves. Nevertheless, Luftwaffe support was still expected and officially requested (though it would never appear).
Mannerheim handpicked Major-General Aaro Pajari to lead the attack. He had already proven his worth as an able field commander; first during the Winter War at the battle of Tolvajärvi and again as the commander of the 18th Division during the attack phase of 1941. Despite the involvement of some 3,500 men and 67 planes, Pajari gave orders for the landing plans to be kept top secret.
The Finns had managed to gather relatively accurate intelligence on the strength of the enemy defences. Suursaari belonged to the Leningrad Naval District and was under the jurisdiction of one of their oldest navy formations, the Baltic Fleet, commanded by Vice-Admiral Vladimir Tributs. The Suursaari garrison was commanded by Colonel Barinov, who in turn reported to the fortress commander at the nearby Lavansaari Island. Despite the island’s significance, the vital bases at Suursaari were manned by only 496 soldiers, 12 officers and the compulsory eight political commissars.
The Finns also understood the strength of the fortifications on the rocky island. The problem was how to transport the chosen few thousand men to the vicinity of the island quietly and unseen, quickly enough and with still enough energy left for the fight. The Arctic landscape provided another challenge: the transports had to somehow traverse undetected across a completely horizontal ice plateau (which was entirely devoid of cover) for dozens of kilometres.
Pajari’s plan was to first move the designated troops into staging areas, near Haapasaari and Luppi islands, about 10–15km away from their targets. He hoped to schedule his attack so that heavy snowfall would help conceal the approaching troops. However, this also meant that the necessary roads across the ice would have to be continuously ploughed to keep them open. Strong winds blowing from the open sea could pile up the snowdrifts so fast that whole roads could vanish within 20 minutes. In order to keep routes and assembly areas clear, five cars and one tractor, all fitted with snowploughs, worked continuously for a total of 408 hours.
All of the men were issued with brand new snowsuits. All their equipment was to be painted white. Furthermore, the 738 horses had to be camouflaged with white sheets and the trucks, sleighs and heavy weapons similarly painted. The troops moved into the area mainly on horse-drawn sleighs or in trucks. As time was of the essence, some men on skis were to be drawn along, holding onto ropes trailing from the crammed trucks. In addition to all the soldiers and their weapons, several bridge sections were taken along, in case the ice cracked and caused a chasm to open across the ice road. White tents were to be set up at 10km intervals along the track. These were to serve as supply points and field hospitals. In the end the total traffic on the ice was so extensive that it was a miracle the Soviets did not notice the preparations for the attack. For the time being, aircraft were only stationed on the mainland. When the time came, they were to be charged with reconnaissance duty and then the support and protection of the infantry during the attack. Additionally, they were tasked with evacuating the wounded and preventing the enemy from withdrawing from Suursaari Island.
The main Finnish attack force was split into two battalions: the 1st Battalion of the 27th Infantry Regiment under Major Lauri Toiviainen, and the 2nd Battalion of the 6th Infantry Regiment under Captain Veikko Elovaara. There was also a reserve coastal guard battalion commanded by Major Åke Sokajärvi in the vicinity of the main attack. Lieutenant-Colonel Lauri Sotisaari led the spearhead with his Detachment S, which was to assault the western shore under cover of darkness. From there his men would then move both north and south along the frozen shoreline while the body of his command took control of the road connecting the two small settlements on the island. Several heavy mortars assigned to the detachment would provide tactical support. A simultaneous attack was also scheduled to start from the opposite, eastern side of the island by Detachment M under Major Martti Miettinen; its role was to prevent the enemy from escaping over the ice, and to act as a distraction from the main assault. Once the enemy dug in to defend, he was to continue his attack towards the two settlements of Suurkylä and Kiiskinkylä. Two light artillery batteries and several anti-tank guns were to provide support for the detachment.
The troops moved into their staging areas and settled into camouflaged tents near the Luppi and Haapasaari Islands. All that was needed was propitious weather. During this crucial time, the Finnish Air Force prevented Soviet planes from approaching close enough to get an idea of the scale of the preparations. On 27 March, once the temperature had dropped to -6°C, Pajari judged that the snow conditions were ideal to launch the attack on skis. Before the assault commenced, each man received a warm meal and 100ml of cognac blended with vodka, in order to give them the boost needed for rapid approach and attack.
The men moved to their jumping-off points. In order to ensure total darkness no fires were permitted and light bulbs were removed from the truck headlights, just in case somebody switched them on accidentally. Unfortunately, the first time the column of vehicles stopped, a long trail of red lights lit up; no one had remembered to remove the bulbs from the brake lights. Luckily for the Finns, this happened far enough away from the Soviet lines that the attackers could continue undetected.
Nevertheless, observers at Suursaari finally realised that something was afoot. On the evening of 26 March at 21:30 the following message was sent to headquarters at nearby Lavansaari Island: ‘About a battalion-strength enemy force seen staging around Haapasaari Island before darkness fell. Special patrols have been sent to observe.’ Lavansaari was at the time snowed in and 40km distant; sending any support there would be slow. However, the island did have an airfield, so in theory at least, air support could be rapidly scrambled.
However, the sighting had come too late. The significance and strength of the Finnish forces was greatly underestimated. After sending the message, Colonel Barinov raised the alarm at Suursaari Island standing his men to. For some reason, instead of sending out patrols to gauge the enemy’s intentions, he was content with letting the troops fight the cold in their foxholes. Although the temperature was only -6°C, the Arctic wind blowing across the ice made matters much worse. At the same time, the increasing snowfall continued to hinder visibility. While the Soviet troops seemed to be hibernating, the Finns approached the island from two directions. Everything was going to plan. Suursaari lay ahead, silhouetted dimly through the billowing snow.
The heavy mortars reached their positions 1.5km from the island, with the light mortars pulled to a mere 500m from the shore. The attack commenced at 04:00 with the troops starting to ski towards the island. When the vanguard of Detachment S was near the western shoreline, the Soviets opened fire. At the same time, the smaller Detachment M had spread out on a wide front on the ice and now engaged the enemy positions from the east. Soon a fierce firefight had developed on both sides of the island. Once the main Finnish forces secured a bridgehead, they started to force their way north and south along the rocky island. Progress was slowed by having to climb steep, rocky cliffs and to wade through ravines filled with deep snow. However, despite the determination of the Soviet defenders, the southerly force soon captured the middle of the island and Kiiskinkylä. At the same time, the majority of Detachment S targeted the rear of Suurkylä and the heavily fortified northern peninsula. A small number of men under Detachment Oksanen were sent to simultaneously secure the southernmost tip of the island from the west.
The Finnish numbers came to bear during the night and through the following morning, when the northern part of Detachment S was able to assault the positions in Suurkylä. Here the Soviets managed to hold out until 15:00. By this time, most of the other important strategic objectives around the island had been captured. Nevertheless, the Soviets continued to resist in several fortified positions across the island and by nightfall, six Soviet fighter planes flew over in support. Twelve Finnish fighters met the enemy planes and proceeded to shoot down four of them. A fifth Soviet aircraft was hit by flak, and only one plane was able to return back to its base at Lavansaari Island.
At this stage, the fiercest opposition came from the Soviets on Selkäapajanniemi Peninsula. There the defenders had used thick timber logs to build extremely strong fortifications in the natural openings in the bedrock. The Finnish Air Force was called upon to soften up these positions. At 17:30, four bombers arrived, strafing the strongholds with machine guns and delivering a total payload of 2,000kg of bombs. By the evening, the Soviet defenders had had enough, and decided to escape over the ice. The Finns pursued them relentlessly across the vastness.
By the bright light of dawn the following morning, the Finns had cleared out the last three fortifications offering resistance at Selkäapajanniemi. This left only one determined enemy stronghold at Lounatrivi lighthouse. So far, the defenders there had resisted all attacks by the Finns. Two pioneer detachments and an artillery squad were sent to resolve the matter. The crew manhandled their gun on top of the piled ice. After setting their sights, they opened fire systematically against the lighthouse, shelling it from the top down a floor at a time. This forced the defenders to flee downwards and eventually out of the front door. Even now, these brave men refused to surrender. They were all killed in the fight that ensued. Kipparniemi Peninsula also held a small Soviet detachment. After completely surrounding the enemy, the Finns concluded that their positions were not strongly fortified. Therefore it was decided to let them stew until the following morning.
The whole of Suursaari finally came under Finnish control on 28 March. That day, Pajari decided to organise a victory parade on the ice in front of the island. Two flights of six Curtis fighter planes each were to fly sentry over the formations. After giving the orders for the procession, Pajari telephoned Mannerheim at his headquarters in Mikkeli: ‘I hereby notify you that I have more or less captured Suursaari Island. Only some minor pockets of resistance remain.’ After the phone call, Pajari found time for a quick nap in his tent. Meanwhile, his men hastened into the parade formations and readied themselves for inspection. The men also had time to assemble a makeshift speaker’s podium on top of a horse-drawn sleigh and a military marching band was even rushed all the way from Helsinki for the occasion. It was extremely risky to organise the parade so soon. Had Soviet planes happened on the scene, the men would have made easy targets on the flat, cover-free ice. Nonetheless, Pajari seemed to have had great faith in the aircraft flying over his men.
The first incident happened after all the men had been inspected, the chaplain had given his sermon and the last of the speeches delivered. At this stage, a lone Soviet machine-gun squad chose to reveal itself and surrender. They had been hiding a mere 100m away from the place where Pajari had been speaking. Had the sergeant in charge of the heavy weapon fancied some posthumous Soviet fame for himself, at least a dozen Finnish soldiers could have been killed. Afterwards, it also came to light that the general and his chief of staff had been positioned directly on top of a minefield. It was sheer good fortune that it had snowed so much, as this prevented the pressure-mines from detonating.
When the excitement of taking care of the surrendering Soviets had died down, a radio message reached Pajari. Twenty-nine enemy planes were approaching the island in three formations of eight, eleven and ten planes. Only one Finnish flight of six Curtiss fighter planes was still in the area while the second flight had already moved nearer to Lavansaari Island. It transpired that the parade had an air show-style finale. The aerial battle quickly developed into a spinning carousel with planes flying in every direction. The six Finnish planes on site engaged immediately with no shortage of targets. The second flight returned quickly from the direction of Lavansaari, attacking the rearmost of the Soviet formations. In the end, the Finns destroyed 18 of the 29 enemy planes without suffering any losses of their own. Earlier the same day, another flight of Brewsters had bagged itself five confirmed kills and a Fokker unit four more. This score of 27 confirmed enemy kills was (to date) the highest one-day tally achieved by the Finnish Air Force. Such triumphs did come with a hefty price: each pilot was forced to fly or be on high alert throughout the day and night. During the last days of the operation, the only way the men kept themselves fit to fly was through heavy use of the German-made combat stimulant Pervitin (methamphetamine). In total, they flew 643 combat missions and delivered over 5,000kg of bombs during the operation.
