 A small Swedish naval unit sailed right into the mighty Russian fleet anchored at Granhamn.A fierce battle took place, the Swedes lost their four frigates after they had run aground but the Russian losses became so heavy that the entire fleet quickly decided to withdraw from Åland, leaving 43 sunken ships and 1000 dead Russians behind.The Russian losses prevented their navy from launching any further major operations until the war ended with the Treaty of Nystad the following year.
