The Battle of Bengtskär was an amphibious landing action fought between Finnish and Soviet forces on 26 July 1941 during the Continuation War.

Background

As a result of the Moscow Peace Treaty, Finland lost the city and port of Hanko to the Soviet Union. The port was used as a base by the Soviet Baltic Fleet from which they could dominate the Gulf of Finland. When the Continuation War broke out in 1941, Finnish forces besieged Hanko. The port in Hanko was within range of the heavy guns at Örö fortress, but a forward observation post was needed to direct their fire. The first forward observation post was set up on islet Morgonland, east of Bengtskär. This post was attacked and overrun by a soviet amphibious assault on July 16. After this, a new observation post was set up at Bengtskär, which was reinforced by a platoon of Finnish marines under the command of Lieutenant Fred Luther.

Battle

Soviet landing troops made a surprise attack on the island of Bengtskär with the goal to blow up the lighthouse situated on the island so that it would not disturb Soviet military operations. Finnish troops situated on the island managed to defend the lighthouse and eventually drove the Soviets back with the help of support troops.^[1] The landing was made with four MO-class patrol boats, while another 6 boats were later dispatched to retrieve the Soviet forces once it was clear the demolition attempt had failed. Finnish gunboats Uusimaa and Hämeenmaa engaged the Soviets, with Uusimaa sinking the patrol boat PK-238 with gunfire.^[2]

Results

The battle resulted in a Finnish victory, due to the intervention of the gunboats. 16 Soviet sailors were saved and captured from the sinking PK-238, while another 13 were captured on the Island. Some Soviet soldiers committed suicide with hand-grenades. Finnish estimates puts Soviet losses at 60 killed (40 of them on land), while Finnish suffered a loss of 16 men in the garrison and 4 men on the ships, while the next day a Soviet aerial bombing killed another 11 men waiting to be evacuated.^[3] Soviet sources report that the landing party consisted of only 31 men: casualties were 31 killed (including 8 sailors) and 24 prisoners (including 16 sailors).^[4]
