Battle of Svensksund - Aftermath

Aftermath

Surviving Russian ships were gathered to Frederikshamn were the badly depleted fleet was being rebuilt while Swedish coastal fleet stayed at Svensksund. Swedes did sent later a squadron of 25 gun sloops closer to Frederikshamn but they were turned back on 5 August by the rebuilt Russian coastal fleet. Swedes withdrew back to Svensksund but Russians did not give a chase.

This defeat encouraged Russia to negotiate with Sweden eventually signing the Treaty of Värälä on 14 August 1790. Neither side gained any territory, however all provisions in the peace treaty of Nystad from 1721 that formally infringed upon Swedish sovereignty were cancelled. After the war the Russians started a massive fortification programme on the eastern, Russian, side of the Kymi river, building the sea fortress Fort Slava and the land fortress Kyminlinna. The forts later grew into the port city of Kotka.
