The operation was later cancelled all together by the Swedish king in preparation to break out the Russian blockage. Some days later the Russians made an unsuccessful attempt at destroying the Swedish Archipelago fleet in the Battle of Björkösund. The Swedes managed to break out and escape at the Battle of Vyborg Bay the day after, but with heavy losses. The two sides then faced each other in the decisive Battle of Svensksund, which marked the ending of the war.
