In wind and heavy snowfall, the I/IR12 crossed the Fjordbotneidet and arrived at Gratangsbotn to find the area cleared of Germans. The soldiers were exhausted after the forced march and went to rest in the farmhouses and barns in Gratangsbotn. For reasons not fully explained, probably a misunderstanding by the battalion's commanding officer, the battalion failed to post a sufficient perimeter security; this was indeed critical as Gratangsbotn geographically is located at the bottom of a kettle with dominating high ground all around.
