The Battle of Suursaari was fought over the frozen Gulf of Finland on and around the islands of Gogland (Finnish language: Suursaari ) and Bolshoy Tyuters (Finnish language: Suur-Tytärsaari ). After sharp fighting the numerically superior Finnish forces captured Gogland and Bolshoy Tyuters, and later provided support for German forces defending Bolshoy Tyuters against Soviet counterattacks.


Soviet forces had occupied Gogland during the Winter War, and, under the terms of the Moscow Peace Treaty, Finland was forced to cede the island to the Soviet Union. As Operation Barbarossa commenced, the Soviets placed a garrison on the island; however, as invading German forces on the mainland moved closer to Leningrad, the Soviet command ordered the evacuation of most of the islands in the Gulf of Finland, as well as their besieged base at Hanko on the Finnish coast.[2]

Soviet forces left the islands of Gogland, Sommers and Bolshoy Tyuters on 7–9 December 1941. Finnish coastal forces noticed that the islands had been abandoned, and manned both Gogland and Sommers with small garrisons by December 12. Poor ice conditions and harsh weather made it difficult for the Finns to reinforce the garrisons, and when Soviet forces returned in company strength on January 2, 1942, the surprised Finns had to withdraw from Gogland.[2]

Capture of Gogland

Determined to retake Gogland, the Finns concentrated a three battalion strong force to the nearby Haapasaaret Islands, which are roughly 20 km NNE of Gogland. Finnish forces were under command of Major General Aaro Pajari and consisted of the second battalion of the 6th Infantry Regiment, or II/JR 6, and the first battalion of the 27th Infantry Regiment, or I/JR 27, and the whole of the 2nd Coastal Battalion (RP 2) supported by the mortar and anti-tank gun companies of the 6th Infantry Regiment, 3rd company of the 23rd Engineer Battalion, 1st Battalion of the 19th Field Artillery Regiment (total of 12 guns), and two artillery batteries (total of 8 guns).[3] The strength of the Soviet garrison was roughly 500 men but it lacked artillery, which meant that the garrison had to fight without support, while the Finns had artillery and air support.

Before the attack Finnish forces opened two roads over the ice to the island's vicinity. Assault troops rode in trucks as far as they could, then, in the pre-dawn hours of March 27, traveled the last five kilometers over the packed ice on skis. Finnish forces were split into two groups, Detachment Sotisaari consisting from bulk of the forces which approached the island from the west and the three company strong Detachment Miettinen which was to pin down Soviet defenders on the east side of the island. Finnish plan called for the regular infantry battalions to spearhead the assault with coastal troops being in reserve.[1]

Assault begun at 0400 on the 27 March 1942 when II/JR 6 reached the island without meeting opposition at which time Finnish artillery starting bombarding the known Soviet strongpoints on the island however the I/JR 27 met determined resistance as it neared its planned entry point and chose to use the same entry point as the other Finnish battalion had used. Finns forces successfully overcome most of the Soviet defenders and captured key locations on the island. However the fatigue from the long march to the island, enemy resistance and difficult terrain forced Finns to halt their assault at 2200 on 27 March 1942 at which time the only remaining Soviet strongpoints were in the extreme southern and northern tips of the island. During the night some of the Soviet forces still on the island chose to flee over the ice. Finns continued clearing the island and the last remaining Soviet strongpoints in the island were cleared in the morning of 29 March.[4] In many cases defending Soviet forces put up very stiff resistance and refused to surrender, forcing the Finns to use satchel charges on Soviet strongpoints. Small numbers of Soviet troops escaped over the ice towards Moshchny Island (Finnish language: Lavansaari ) though the fleeing men suffered losses as Finnish Air Force fighters repeatedly strafed them.

Air activity was high on both sides. On March 27–28 Finnish Air Force Fokker D.XXI, Curtiss P-36 Hawk and Brewster F2A Buffalo fighters claimed a total of 27 Soviet Polikarpov I-153 and Polikarpov I-16 fighters.[5] Air forces on both sides supported their ground forces with strafing and bombing runs, the Finns using twin engined Bristol Blenheim and Tupolev SB-2 bombers.

Capture of Bolshoy Tyuters

On March 30, 1942, with Gogland secured, the Finns sent a small patrol to investigate Bolshoy Tyuters. A strong Soviet garrison forced the patrol to depart. A stronger force was sent to capture the island on April 1, and by the time the company-sized force reached the island the Russians had abandoned it. On the following day the Russians returned, and despite Finnish resistance, managed to create strongpoints on the island. With German support, Finnish troops eventually managed to destroy or drive off the remaining Soviets.


On April 8, 1942, after the Germans had transported artillery to the Bolshoy Tyuters, the Soviets launched another attack. The assault force was estimated to have been roughly 1,200 men strong, but the heavy German artillery on the island and lack of cover on the frozen Gulf of Finland caused heavy casualties among the Soviets. After the attack had been repulsed the Finns left the island to the Germans, who occupied it until they evacuated Estonia in 1944. Though the operation to capture Gogland had succeeded, the overall goal of capturing all the main islands in the Eastern Gulf of Finland failed, as the German forces needed for the operation were required to defend against Soviet counter-offensives on the Leningrad Front.[2]
