Gundacar were defeated and obliged to accept peace by Aetius and Avitus; however, the following year he sent Hun foederati to destroy them. Allegedly 20,000 Burgundians were killed in a slaughter which probably became the basis of the Nibelungenlied, a German epic. That same year Aetius was probably in Armorica with Litorius to suppress a rebellion of the Bagaudae under a certain Tibatto. The year 437 saw his second consulship and the wedding of Valentinian and Licinia Eudoxia in Constantinople; it is probable that Aetius attended the ceremony that marked the restoration of the direct rule of the Emperor. At that time his general Litorius had broken the siege of Narbona and had turned the war in favor of the Romans. The following two years were occupied by a campaign against the Suebi and by the war against the Visigoths; in 438 Aetius won a major battle (probably the Battle of Mons Colubrarius), but in 439 the Visigoths defeated and killed Litorius and his Hun Foederati. Aetius returned to Gaul after Vetericus had stabilized the situation, and defeated the Visigoths and obtained a treaty. On his return to Italy, he was honoured by a statue erected by the Senate and the People of Rome by order of the Emperor; this was probably the occasion for the panegyric written by Merobaudes. In 443, Aetius settled the remaining Burgundians in Sapaudia, south of Lake Geneva. His most pressing concern in the 440s was with problems in Gaul and Iberia, mainly with the Bagaudae. He settled the Alans around Valence in 440 and along the Loire including Aurelianum in 442 to contain unrest in Armorica. In Spain, Aetius was slowly losing his grip on the situation. In 441 he appointed Asturius Magister Militum per Hispanias, in order to put down the Bagaudae in Tarraconensis. He was recalled and Merobaudes defeated the Bagaudae of Aracellitanus in 443. In 445 the Romans had the Vandals attack Turonium in Gallaecia, followed by Vitus who campaigned with a combined force of Romans and Goths in 446, but was ultimately defeated. The Bagaudae in Armorica revolted again in 447 or 448, and were put down by the Alans of Goar. As a result, the leader of the revolt Eudoxius fled to the court of Attila the Hun. In 449 the Bagaudae in Spain revolted and sacked Tyriasso, Caesaragusta, and Illerdensus. The Suebi also entered Tarraconensis to assist Basilius
