Start In 436, while the Roman army was dealing with a
Bagaudae uprising in
Gallia Lugdunensis and a resurgence of Burgundian activity, Theodoric terminated the treaty with the Romans. According to Hughes, an alliance formed between the Goths and the Burgundians, prompted by Theodoric's dissatisfaction with Roman rule and his desire to expand into areas bordering the Mediterranean. Theodoric launched invasions into neighboring regions, prioritizing the capture of Narbonne, a key coastal city. His forces besieged the city, while also securing access to Spain by defeating garrisons stationed at the Pyrenean passes.
Aetius's reaction The Roman army took some time to mobilize against the Goths. Aetius, the commander-in-chief of the Western Roman army, was in Italy attending games held to celebrate his appointment as
patrician. The simultaneous outbreak of the Gothic and Burgundian revolts compelled him to deploy the army efficiently. In Gaul, he only had the Comitatenses field army at his disposal. General Litorius had already been sent to suppress the Bagaudae insurgents with a part of this force. Aetius, who had established a delicate peace throughout his vast empire, was reluctant to lead the Goths with units from other regions, as he feared it would leave those areas vulnerable. Instead, he sent a delegation to the court of the Hun King
Rua, requesting military assistance. Although the timing is uncertain, it is highly likely that in 436–437, the Huns were granted parts of
Pannonia near the River Save. Prior to the arrival of this army in Gaul, Aetius utilized the available forces to suppress the combined Gothic and Burgundian uprising.
Litorius's campaign In 436, General
Litorius successfully suppressed the Bacaudian uprising in Armorica. He then led his army southward and, in 437, joined forces with a contingent of Huns to quell the Gothic revolt. Litorius focused his efforts on
Narbonne, which was under siege by the Goths. However, upon the arrival of the Roman forces, the Goths retreated, leaving the city relieved. Subsequently, Litorius engaged the Goths in Aquitaine, shifting the conflict to the heartland of Gothic territory. Theodoric's army found itself progressively pushed into a defensive position, eventually retreating to its stronghold in the capital,
Toulouse, which came under siege by the Romans. Following a prolonged siege, Theodoric eventually surrendered to General Litorius.
Armistice and resumption of the war Theodoric was forced to lay down his arms and honor the treaty with the Romans, which obligated him to provide troops to the Roman army in the event of a setback against the
Suebi in Spain in 438. Despite the reconciliation between the Goths and Romans, hostilities resumed. Historians speculate that developments in Spain and the Mediterranean, where the Vandals were increasingly engaged in piracy, contributed to this resurgence of conflict. Sources indicate a renewed large-scale war that initially challenged the Goths. Upon Aetius's return to Ravenna following the marriage of Valentinian III and Licinia Eudoxia in Constantinople in early 438, he made changes to the command structure of the army in Gaul. Avitus, likely serving as magister militum per Gallias, assumed the role of
praefectus praetorio Galliarum, with Litorius succeeding him. Aetius himself temporarily assumed supreme command and actively participated in the war effort.
Battle of Mons Colubrarius One of the few notable achievements documented regarding Aëtius' involvement recounts a significant victory he achieved in a pivotal battle, during which he purportedly vanquished 8,000 Goths. Given the political exigencies in Ravenna, Aëtius found it necessary to entrust the continuation of the Gothic war to Litorius after this engagement. In recognition of his efforts, the emperor commissioned the erection of a statue in his honor, with Merobaudes delivering laudatory remarks. Presumably, Aëtius possessed ample confidence in the strategic acumen of his generals, Litorius and Sigisvult, particularly considering the substantial setback the Goths had previously suffered.
Battle of Toulouse In 439, the Visigoths were forced to retreat to their capital,
Toulouse, due to increasing defensive pressure from the Romans. The Roman army, led by General Litorius, besieged Toulouse. King Theodoric I of the Visigoths attempted to attack the Roman camp during the siege but failed, resulting in heavy losses for his army. According to Prosper, "due to the thoughtfulness of the Romans, the opportunities turned and the Goths became the parent party." Additionally, after the failed attack, General Litorius was captured by the Goths and executed. In the midst of the ensuing chaos, Vetericus, a Goth serving in the Roman army, temporarily assumed leadership. Prosper briefly states, "in the same period Vetericus was considered loyal to our state and known for the frequent demonstration of his skill in war". Vetericus successfully stabilized the situation following Theodoric's disastrous attempt. Subsequent battles occurred, and the Romans dispatched new troops, mainly consisting of auxiliary forces from the Huns, to confront the Goths. == End of the war and consequences==
