 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.
