Although quarrels and reconciliations between the three kings followed each other in quick succession, in general it may be said that Louis favoured annulment, and Charles opposed it, while neither lost sight of the fact that Lothair had no sons to inherit his lands.

Waldrada, put away Teutberga, but
Hucbert took up arms on her behalf, and after she had submitted successfully to the
ordeal of water, Lothair was compelled to restore her in 858. Still pursuing his purpose, he won the support of his brother, Emperor
Louis II, by a cession of lands and obtained the consent of the local clergy, such as
Adventius of Metz, to the annulment and to his marriage with Waldrada, which took place in 862.
