To the frustration of the Parisians who had fought for a long time to defend the city, Charles stopped short of attacking the Viking besiegers, and instead allowed them to sail further up the Seine to raid Burgundy (which was in revolt), as well as promising a payment of 700 livres (257 kg) of silver.
Til frustration for pariserne, der havde kæmpet for at forsvare byen mod vikingerne så læng, så angreb Karl ikke vikingerne, men tillod dem i stedet at sejle længere op af Seinen for at plyndre i Bourgogne (hvor der var oprør), og han lovede dem en betaling på 700 livres (257 kg) sølv.
