Vyborg Bay
Battles in Vyborg Bay started on June 30 with the Soviet 224th Rifle Division's attempt to capture the islands of Teikari and Melansaari. Finnish forces on the islands drove the attacks back, inflicting heavy losses on the Soviet troops in the process. Renewed Soviet attacks on July 4 met success in the islands near Uuras, but the attempt to land on Teikari was again repulsed with heavy Soviet losses.
