Background

After the Swedish main army commanded by King Charles XII was destroyed in the Battle of Poltava in 1709, Finland was exposed to Russian attack. An attack on Uusimaa was expected from the fall of Vyborg in the summer of 1710. Helsinki had become an important military base for Sweden during the war, but the city had not been fortified except for modest earth ramparts. The Russian Navy had visited Porvoo with a surprise attack already in 1708. The plight of Helsinki had been deepened by the plague outbreak in the fall of 1710, which killed the majority of the city's inhabitants.

After the death of Carl Nieroth in January 1712, Governor Georg Lybecker, who had already been removed from the same position once due to the loss of Vyborg, was returned as commander-in-chief of the Swedish forces in Finland. The Russian archipelago fleet commanded by Ivan Botsin threatened Helsinki in September 1712, but had to retreat when the Swedish fleet hit the spot. The Neva squadron, which was part of the Swedish fleet, was superior in the open sea, but could not move in the shallow waters of the coast, so the Russian galley fleet controlled the coastal waters of Eastern Uusimaa. However, the Neva squadron, commanded by Admiral Olof Wernfelt and later Admiral Erik Johan Lillie, sailed to its navy base at Karlskrona ahead of the winter freeze of 1712–1713.

After securing peace with the Ottoman Empire in the south, Russian tsar Peter the Great finally decided in 1713 to attack Finland in order to force Sweden to peace in a war that had been going on for 13 years. As soon as the Gulf of Finland was freed from the ice, a fleet of more than 200 light ships (including 110 landing crafts, 93 light galleys, and at least two gun prams and one mortar galliot), commanded by Admiral Fyodor Apraksin, set off from the Kotlin Island, accompanied by 17,000 infantry soldiers, or 18,700 men in total. The first target was Helsinki, from which St. Petersburg wanted a supply center for the Russian army for operations extending deeper into Finland. The Tsar himself sailed with the fleet.
