The Battle of Kringen (Norwegian: Slaget i Kringom) involved an ambush by Norwegian peasant militia of Scottish mercenary soldiers who were on their way to enlist in the Swedish army for the Kalmar War.
The battle has since become a part of folklore in Norway, giving names to local places in the Ottadalen valley. A longstanding misconception was that George Sinclair, a nephew of the George Sinclair, 5th Earl of Caithness was the commander of the forces; in fact, he was subordinate to Lieutenant Colonel Alexander Ramsay.
The Scottish forces (Skottetoget) were partly recruited, partly pressed into service by Sir James Spens, apparently against the preferences of James VI, who favored the Danish side in the war. Two ships sailed from Dundee and Caithness in early August, met up on the Orkney Islands and sailed for Norway.
Because sea routes had been blocked by Danish forces in the Kalmar War, the Scottish forces decided to follow a land route to Sweden that other Scottish and Dutch forces had successfully used. On 20 August the ships landed in Isfjorden in Romsdal, though the pilot apparently put the forces on shore in rough terrain. The soldiers proceeded to march up the valley of Romsdalen and down the valley of Gudbrandsdalen.
