Finnish gunboat Turunmaa
On 29 August Turunmaa together with Karjala, Hämeenmaa and Uusimaa escorted by Riilahti and Ruotsinsalmi sailed through the main Soviet minebarrier south of Hanko to the eastern Gulf of Finland.[11] On 1942 Turunmaa like other Finnish gunboats was tasked with guarding of the minebarriers northeast of Hogland and performing anti-submarine patrols in the same region.On 8 August Turunmaa was sortied to fend off the Soviet attack on Someri but arrived several hours after Hämeenmaa and Uusimaa.After the naval action had already ended Turunmaa was slightly damaged by a near-miss by a bomb and suffered some crew losses (2 dead, 8 wounded) as overheated barrels of both of the 20mm Madsen guns aboard exploded.[12] On 2 May 1943 while guarding the mine barriers northeast of Hogland, Turunmaa was seriously damaged in an air raid and the sinking ship had to be beached to shallow water at Haapasaaret (group of islands south from Kotka).
