his dominions amongst his three elder sons; and took away from two of them, in Burgundy and Allemannia, some of the territories he had assigned to them, and gave them to the boy Charles for his share.  Lothaire, Pepin, and Louis thereupon revolted.  Court rivalries were added to family differences.  The emperor had summoned to his side a young Southron, Bernard by name, duke of Septimania and son of Count William of Toulouse, who had gallantly fought the Saracens.  He made him his chief chamberlain and his favorite counsellor.  Bernard was bold, ambitious, vain, imperious, and restless.  He removed his rivals from court, and put in their places his own creatures.  He was accused not only of abusing the emperor’s favor, but even of carrying on a guilty intrigue with the Empress Judith.  There grew up against him, and, by consequence, against the emperor, the empress, and their youngest son a powerful opposition, in which certain ecclesiastics, and, amongst them, Wala, abbot of Corbie, cousin-german and but lately one of the privy counsellors of Charlemagne, joined eagerly.  Some had at heart the unity of the empire, which Louis was breaking up more and more; others were concerned for the spiritual interests of the Church which Louis, in spite of his piety and by reason of his weakness, often permitted to be attacked.  Thus strengthened, the conspirators considered themselves certain of success.  They had the empress Judith carried off and shut up in the convent of St. Radegonde at Poitiers; and Louis in person came to deliver himself up to them at Compiegne, where they were assembled.  There they passed a decree to the effect that the power and title of emperor were transferred from Louis to Lothaire, his eldest son; that the act whereby a share of the empire had but lately beer assigned to Charles was annulled; and that the act of 817, which had regulated the partition of Louis’s dominions after his death, was once more in force.  But soon there was a burst of reaction in favor of the emperor; Lothaire’s two brothers, jealous of his late elevation, made overtures to their father; the ecclesiastics were a little ashamed at being mixed up in a revolt; the people felt pity for the poor, honest emperor; and a general assembly, meeting at Nimeguen, abolished the acts of Compiegne, and restored to Louis his title and his power.  But it was not long before there was revolt again, originating this time with Pepin, king of Aquitaine.  Louis fought him, and gave Aquitaine to Charles the Bald.  The alliance between the three sons of Hermengarde was at once renewed; they raised an army; the emperor marched against them with his; and the two hosts met between Colmar and Bale, in a place called le Champ rouge (the field of red).  Negotiations were set on foot; and Louis was called upon to leave his wife Judith and his son Charles, and put himself under the guardianship of his elder sons.  He refused; but, just when the conflict was about to commence,
