It was, however, twelve years before the Mussulman’s hope of adding Gaul to the Empire of the Caliph received its death-stroke. In 725 they penetrated as far as Autun, in the very heart of Burgundy, demolished the city and carried off the treasures of the Church to Spain. The vigilance of Eudo of Aquitaine seems to have relaxed, and he was now no longer, as in 720, the great champion of Gaulish Christendom against the invader. On the contrary he entered into friendly relations with at least one Mussulman warrior, bestowing his daughter Lampegia on Munuza, a Berber chieftain, who seems to have been striving to establish a Moorish kingdom in Spain independent of the Caliphs. It was perhaps owing to this new combination that Eudo broke through the treaty which he had made with Charles in 720. There were thus two princes, a Christian and a Moor, Eudo and Munuza, each rebelling against the state to which they nominally owed allegiance. However, neither attempt at independence was destined to succeed: Charles twice crossed the Loire in the year 731, defeated Eudo in battle, apparently near the city of Bourges, and returned home with great booty, having effectually checked the separatist designs of the Aquitanian chief. About the same time apparently, Abderrahman, the legitimate representative of the Caliph of Damascus, overthrew the Berber chief Munuza and hunted him into the Pyrenees, where he was overtaken while resting by a fountain. Munuza fell pierced with many wounds, and his bride, Eudo’s daughter, was sent to end her days in the Caliph’s harem.
