The Russian had about 3,600 men in the area under the command of Lieutenant General Karl Gustav von Baggovut.

The initial phases of the operation were quite successful for the Swedes, who managed to advance several kilometers and eventually have Turku in sight.

However, the units of the Libau Infantry Regiment with one gun launched the first Russian counterattack and they pushed the advanced Swedish troops back to the main defense line.

Lieutenant von Vegesack (the son of the general) found the Russian left flank open and attacked immediately.

In the early morning the Libau Infantry Regiment made the Swedish troops retreat again back to the main defense line.

Von Vegesack ordered all of the men from the nearby islands to the Lemo battlefield and strengthened the defense line.
