882 – Battle of Remich, Luxembourg
When the Vikings cross the Channel and start raiding in Francia from 879 onwards, they are stopped by Louis the Youger, king of the East Franks at Thimeon (880), and Louis III, king of the West Franks at Saucourt (881). Yet, neither king moves to obliterate the Northmen. Undeterred they move further inland until they are stopped by the Franks at Remich. They meet an army of the count of Metz and the archbishops of Metz and Trier. The Vikings win, but do not press further southwards.
