Vikings moved east and entered Aachen, where they burned down emperor castle and they used the Maria church as stable for their horses. Vikings did not stop they moved down to the Rhine area, where they extorted contributions from Cologne, Bonn and Koblenz.
They marched through the Mosel valley and burned Trier down to the ground. Theses areas was previous free from viking raids and the terrified population is shocked and helpless against the viking raids. In the summer Charles the fat attacked Elsloo with large west and southern German forces, but the emperor did not have the guts for a full scale battle and instead paid Sigfred and Gudefred 2500 Lbs gold and silver to remove the viking army.
Charles the fat also had to let Roric`s old Friesland area be ruled by Gudefred, which made the vikings in control of a legal base for further raids. Sigfred sent his vikings into West Francia and the area between the rivers Oise,Somme and Aisne is looted merciless, the army camped in Amiens.
The invasion at the Laon region failed an attempt to take it but ransacked the area as well as the district of Villette Saint Vincent, destroying the churches and abbeys : Saint Jean du Bourg and Saint Hilaire Saint Vincent.
