The Battle of Kokonsaari was fought between Swedish and Russian forces at Kokonsaari in Finland on 11 July 1808 during the Finnish War. Background After the Battle of Lintulaks the Swedish commander Otto von Fieandt received reinforcements from the Swedish Field-Marshal Wilhelm Mauritz Klingspor, which increased his forces to about 1,200 men with 4 guns to protect the highway leading to Kokkola. The Russians opposing him likewise saw their forces grow to the size of about 3,100. The Russians attacked the Swedes on July 11 and once again met them deployed in an overextended line — with gaps and no reserve — extending two kilometres crossed over the Kokkola highway, with their right flank protected by the Perho river. As in the previous battle, the Russians kept several battalions as reserve while still heavily outnumbering the Swedes in the attack. Swedish forces Åbo Infantry Regiment (1 Battalion) Nyland Infantry Regiment (1 Battalion) Tavastehus Infantry Regiment (2 companies) Savolax Infantry Regiment (2 companies) Savolax Jäger Regiment (2 companies) Nyland Dragoon Regiment (20–50) Finnish Artillery Regiment (4 guns) In total: 1,200 men and 4 guns Battle The Swedes resisted stubbornly, the artillery on both sides duelled near the highway while the infantry fought intensely out on the bog; some Swedish battalions counterattacked and pushed several Russian lines back, until their reserve gave them enough weight to repulse the Swedish attack. Jankovitj then reinforced his right flank with two battalions from the reserve — to encircle the Swedish left and gain access to the highway from behind — while his other battalions increased their activity at the front; this forced Fieandt to withdraw one kilometre, where he once again made a brief stand at a forest edge to buy time for the collection of wounded, before he eventually ordered a retreat towards Tunkkarin Silta, five kilometres away. The skirmish at Kokonsaari had proved to be one of the more intensely fought engagements during the whole war. The Swedish casualty report mentioned 159 privates and seven officers killed or wounded, however, this number excludes missing (an additional killed and captured); it is therefore likely that the total casualties in dead and wounded reached a sixth of their fighting force, excluding the prisoners. The Russians had lost 16 officers and around 300 privates. The Swedish force had stood well up against the much larger Russian and their retreat had been executed in good order. Aftermath
