In 586 he was at Coblenz, and on his return to Yvois (the modern Carignan) visited the stylite Wulfilaic; in 588 we hear of him at Metz and also at Chalon-sur-Saone,whither he was sent to obtain from King Guntram the ratification of the pact of Andelot; in 593 he was at Orleans, where Childebert had just succeeded his uncle Guntram.
By the pact of Andelot in 587 Childebert was recognized as Gontran's heir, and with his uncle's help he quelled the revolts of the nobles and succeeded in seizing the castle of Woewre.
He adopted him as his son, and recognized him as his heir at the treaty of Andelot (587); he also helped him to crush the great lords, especially Ursion and Berthefried, who were conquered in la Woevre.
She endeavoured to prevent the alliance between King Guntram and Childebert, which was cemented by the pact of Andelot; and made several attempts to assassinate Childebert by sending against him hired bravoes armed with poisoned scramasaxes (heavy single-edged knives).
He declared himself the protector of Fredegond, but his death in 593 delivered up Burgundy and Neustria to Brunhildas son Childebert, king of Austrasia, in consequence of the treaty of Andelot, made in 587.
The treaty of Andelot in 587 had already decided that the benefices or lands granted to them by the kings should be held for life.
