Soviet troops attempted to establish a beachhead west of the Finnish city of Viipuri across the frozen Viipuri Bay, while pressure was asserted on the city from its south and east. An attempt was orchestrated on 29 Feb 1940 without success; likewise, this newly dispatched unit failed to establish a beachhead, however, the Soviet troops were able to capture the coastal battery on the island of Tuppuransaari, which had caused high casualties on both attempts.
