After learning that a small Russian gun sloop unit had moved to relatively vulnerable position at the southern end of Airisto region Hjelmstjerna made the decision to attack.

Later during the second day Swedish reinforcements arrived and Hjelmstjerna planned to launch his renewed attack during the night using galleys and their greater crew complements to overpower the smaller Russian vessels.

[1] While preparing for the attack Hjelmstjerna neglected to guard the narrow passage that led from Rimito Kramp towards Turku.

During the night little before planned Swedish attack the Russians fled to Turku where they were further reinforced in addition to being supported by three 24-pounder artillery batteries.
