Hugh the Great
Later Herbert allied with Hugh the Great and William Longsword, duke of Normandy against King Louis IV, who allocated the County of Laon to Roger II, the son of Roger I, in 941. Herbert and Hugh the Great took back Rheims and captured Artaud. Hugh, the son of Herbert, was restored as archbishop. Again the mediation of the German King Otto I in Visé, near Liège, in 942 allowed for the normalization of the situation.
