[6] In 923, Count Herbert took the bold step of imprisoning King Charles III, who died still a captive in 929.

[a][4] Then, on the death of Seulf in 925, with the help of King Rudolph, he acquired for his second son Hugh (then five years old) the archbishopric of Rheims.

[3] Using the threat of releasing King Charles III, whom he held captive, Herbert managed to hold the city for four more years.

[11] The intervention of his ally, Henry the Fowler, allowed him to restore his domains (except Rheims and Laon) in exchange for his submission to King Rudolph.

[12] Again the mediation of the German King Otto I in Visé, near Liège, in 942 allowed for the normalization of the situation.

Herbert II died on 23 February 943 at Saint-Quentin, Aisne (the capital of the county of Vermandois) from natural causes.
