The Siege of Asselt was a Frankish siege of the Viking camp at Asselt in Frisia in the year 882. Though the Vikings were not forced by arms to abandon their camp, they were compelled to come to terms whereby their leader, Godfrid, was converted to Christianity. The campaign over, Charles returned to Koblenz and there dispersed the army. His reputation as a weak and inept ruler stems largely from this campaign, though contemporaries did not in general see it as a failure. Only the Mainz cleric of Liutbert's, adding to the annals of Fulda had that impression.
