Following the Battle of Thimeon near Charleroi where the Vikings were defeated by Louis the Younger, King of East Francia, they resumed their raids on the Frankish kingdom, reaching Kortrijk in November 880 and Cambrai and Arras in December. Earlier in 881, they sacked Amiens and Corbie. Louis and Carloman were victorious in what must have been a rare pitched battle against the northern raiders in which some 8,000 Vikings were slain. The battle is celebrated in the Old High German poem Ludwigslied. The hamlet of Saucourt is between Valines and Fressenneville, around 10 miles west of Abbeville.
