In 500 A.D. Clovis reduced the Burgundiones to a state of semi-dependence, after a fierce and bloody battle with Gundobald, their king, at Dijon on the Ouche. In this conflict, as in almost every other, Clovis attained his ends in a great measure by turning to account the dissensions of his enemies. Gundobald had called upon his brother Godegisil, who ruled over one division of their tribe, to aid him in repelling the attack of the Franks. The call was answered, in appearance at least; but in the decisive struggle Godegisil, according to a secret understanding, deserted with all his forces to the enemy. Gundobald was of course defeated, and submitted to conditions which, however galling to his pride and patriotism, could not have been very severe, since we find him immediately afterwards punishing the treachery of his brother, whom he besieged in the city of Vienne (the Roman Vienna), and put to death in an Arian church.
The circumstances of the times, rather than the moderation of Clovis, prevented him from calling Gundobald to account. A far more arduous struggle was at hand, which needed all the wily Salian’s resources of power and policy to bring to a successful issue—the struggle with the powerful king and people of the Visigoths, whose immediate neighbour he had become after the voluntary submission of the Armoricans in 497 A.D. The valour and conduct of their renowned king Euric had put the western Goths in full possession of all that portion of Gaul which lay between the rivers Loire and Rhone, together with nearly the whole of Spain. That distinguished monarch had lately been succeeded by his son Alaric II, who was now in the flower of youth. It was in the war with this ill-starred prince—the most difficult and doubtful in which he had been engaged—that Clovis experienced the full advantages of his recent change of faith. King Euric, who was an Arian, wise and great as he appears to have been in many respects, had alienated the affections of multitudes of his people by persecuting the Catholic minority; and though the same charge does not appear to lie against Alaric, it is evident that the hearts of his orthodox subjects beat with no true allegiance towards their heretical king. The baptism of Clovis had turned their eyes towards him, as one who would not only free them from the persecution of their theological enemies, but procure for them and their church a speedy victory and a secure predominance. The hopes they had formed, and the aid they were ready to afford him, were not unknown to Clovis, whose eager rapacity was only checked by the consideration of the part which his brother-in-law Theodoric, king of the Ostrogoths, was likely to take in the matter.
This great and enlightened Goth, whose refined magnificence renders the contemptuous sense in which we use the term Gothic more than usually inappropriate, was ever ready to mediate between kindred tribes of Germans, whom on every suitable occasion he exhorted to live in unity, mindful of their common origin. He is said on this occasion to have brought about a meeting between Clovis and Alaric on a small island in the Loire in the neighbourhood of Amboise. The story is very doubtful, to say the least. Had he done so much, he would probably have done more, and have shielded his youthful kinsman with his strong right arm. Whatever he did was done in vain. The Frankish conqueror knew his own advantages and determined to use them to the utmost. He received the aid not only of his kinsman Sigebert of Cologne, who sent an army to his support under Chararic, but of the king of the Burgundians (Burgundiones), who was also a Catholic. With an army thus united by a common faith, inspired by religious zeal, and no less so by the Frankish love of booty, Clovis marched to almost certain victory over an inexperienced leader and a kingdom divided against itself.
