Phase 1 (Sunday 19 June)

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. Von Vegesack attacked immediately to the Russian center. The Russian commander Baggovut received reinforcements and he attacked with divided forces; 2 companies attacked on the right, 2 companies on the left, and 2 companies with the gun in the center. Lieutenant von Vegesack (the son of the general) found the Russian left flank open and attacked immediately. The Russians had to withdraw a few kilometers in defense. The Swedish troops followed.

Phase 2 (Monday 20 June)

Major General Nikolay Borozdin collected more reinforcements: 300 men from the Brest Infantry Regiment, two more guns, and one squadron of the Finland Dragoon Regiment. 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.

Baggovut received the Pernov (Pärnu) Musketeer Regiment as additional reinforcement. The Russian launched the whole front attack with bayonets; the Pernov Regiment on the right, the Libau Regiment in the center, and the Brest Regiment on the left. The Russian artillery set fire to the Ala-Lemo Manor house. The Swedes were forced to pull back and eventually evacuate to their ships. The fortifications at the shore and later the gunboats defended the fleeing Swedes. The Russian artillery moved to the shore and fired at the Swedish fleet. Von Vegesack pulled both the land and sea forces back to the Åland Islands.

After the battle the Russian reserve forces at Yli-Lemo were 2 companies from the Nevski Regiment and ½ squadron of the Finland Dragoon Regiment.
