The Swedish army had problems repairing the bridge due to constant fire from the Norwegian side of the river.
It was then a small Swedish force of 75 men, consisting of jägers from the Bohuslän and Life Grenadier Regiments, passed over the river at a hidden point.
Once over they waited for reinforcements but none came; but instead the order of attacking the vastly larger Norwegian force.
As more Swedish troops crossed, the Norwegians quickly left the stand.
The Convention of Moss, providing a cease fire agreement, was signed that same day.
