That summer Swedish reconnaissance indicated that the Norwegians were themselves gathering forces in Trondheim and Røros and preparing for an attack across the border. Sparre received a dispatch from Magnus Gabriel De la Gardie encouraging him to prevent this attack by moving his men either towards Trondheim or alternatively to Røros and on through the valley of Gudbrandsdal to Värmland. Sparre chose the latter alternative, detaching major Carl Rutencrantz with a force to Oviken, but delaying his own departure to await a promised complement of 1,400 men from Österbotten. Sparre also attempted to muster troops and supplies from Jämtland itself, but like in Skåne and Bohuslän the people were still loyal to their former masters. The Swedes were barely tolerated, and promised supplies and horses never appeared. When the troops from Österbotten finally arrived, they numbered only 290, and were poorly armed and trained. Short of ammunition and unable to feed his troops, Sparre was again forced to scatter his troops to live off the land.
