Soviet 7th Army, while attacking Finnish defense fortifications, received flanking fire from coastal batteries on the island of Saarenpää; in response, Soviet battleship Oktjabrskaja Revolutsija bombarded the island, but failed to hit the batteries due to heavy fog. In the Gulf of Finland and the Gulf of Bothnia, Soviet submarines sank three ships going in and out of Finnish ports; two of them actually flew German flags.
