Battle of Nerva Island

No major Soviet warships were in action (most of them were blocked in Leningrad), and the Soviet Navy engaged possessed in the area 4 small gunboats, 10 patrol boats (MO-4-class submarine chasers), and 14 motor torpedo boats.^[1] German torpedo boats shelled the Soviets but caused only damage to the two gunboats MBK-503, MBK-505 and on the MO-106, without sinking them. The Soviets counter-attacked with their motor torpedo boats, the first attack was repelled with damage to TK-53, TK-63 and TK-153, while the second attack was another failure with damage to TK-101 and TK-103. Finally, TK-37 and TK-60 made a pincer attack and launched their torpedoes at the same time against T31, the German torpedo boat was hit and sunk. Other sources give credit to the victory only to TK-37.^[2] 76 German sailors lost their lives, while 6 were captured by Soviets. Finnish units rescued other German sailors (including 23 wounded, two died of wounds^[3]). After the loss of her sister ship, T30 retreated after having suffered light damage (one sailor killed and 13 wounded). Germans claimed to have sunk a number of Soviet attacking motor torpedo boats but actually despite some were damaged, none was sunk.

The battle resulted in a rare naval victory for the Soviets. The German forces failed to sink any Soviet ship, while they lost a torpedo boat. The following month, on 16 July 1944, the Germans attempted a repetition of the mission (“Operation Buckenwald”), engaging torpedo boats T30, T8 and T10, the action resulted in a brief inconclusive skirmish with Soviet torpedo boat Tucha and minesweepers T-211 Rym and T-217 Kontr-Admiral Yurkovskiy. No damage occurred to the major warships, although shortly before the fight the Soviets suffered damage to two small patrol boats.^[4]
