Another contingent, under Axel Otto Mörner, failed to break through the lines at Toverud, under Weibye, resulting in the capture of the Swedish force—except for 13 men who managed to escape to the main army at Haneborg.

On April 14, 1808 the Swedish 2nd Brigade under Colonel Schwerin had crossed the Swedish-Norwegian border at Skillingfors and marched westwards towards Aurskog and Høland.

Major Friederich Christopher von Ditten, who was commander of the small Norwegian outposts stationed in the area, chose to pull his forces back across the river Glomma instead of attacking the Swedes.

This meant that the road was open for Count Axel Otto Mörner's cavalry unit, who then occupied the undefended Blaker entrenchment on 16 April.

Major Paul Weibye had from Prince Christian August's plan advanced in the direction of Blaker with five companies and 40 dragoons to find a suitable place to stop the enemy, and chose to occupy Toverud farm in the afternoon on 19 April.
