Battle of Vézeronce

On 25 June 524 near Vézeronce (Isère), Chlodomer faced Godomar III in the second Frankish expedition against Burgundy. After Sigismund and his sons were executed on Chlodomer’s orders (523), Clovis’s sons resumed the campaign in spring 524: Chlodomer took Lyon without a fight, pursued the Burgundian army toward the Alps and met it on a vast plain. The Franks first gained the upper hand, but Chlodomer, thinking he was joining Frankish horsemen, threw himself among enemies who killed him and displayed his head. Sources diverge on the outcome: Gregory of Tours (close to the Franks) claims a Frankish victory; Agathias credits the Burgundians; Marius of Avenches only notes the battle and Chlodomer’s death. The Burgundian kingdom survived another decade — strong evidence of a Frankish defeat — until the conquest of 534.

After Clovis’s death (511), his sons continued expansion. Clotilde, a Burgundian princess and Sigismund’s aunt, pushed to avenge Chilperic. In 523 a first incursion captured Sigismund, executed with his two sons on Chlodomer’s orders. Godomar III succeeded him and organized resistance. In spring 524 Chlodomer, Childebert, Chlothar and Theuderic (half-brother, Sigismund’s son-in-law via Suavegotha) launched a new war. Chlodomer advanced on Lyon, took it without fighting, sought contact with Godomar who fell back toward the Alps. The meeting took place around Vézeronce, a plain — not an alpine ambush. A Byzantine-craft helmet found in the Rippes de Pillardin / Saint-Didier marshes is kept in Grenoble and likely belonged to a Frankish chieftain.

On a vast plain Chlodomer’s troops quickly gained the advantage and pushed back the Burgundians. Chlodomer, believing he was joining Frankish cavalry, threw himself among enemy warriors who seized and killed him; his head was stuck on a pike and shown to the Franks. Gregory claims that, seeing their chief beheaded, the Franks regained energy and won — a partisan reading. Agathias gives victory to the Burgundians; Marius of Avenches confines himself to the fact and the king’s death. No ancient source details orders of battle or strengths. Alpine-ambush hypotheses do not match the plain description. The “Mollard de Coyne,” a mound sometimes called the king’s grave, is a natural formation.

Godomar held the field; the Burgundian kingdom survived about ten years. Chlodomer’s death upset the Merovingian partition: his brothers had two of his sons murdered (the third, Cloud, became a monk) and shared his Orléans kingdom. Only in 532 did Childebert and Chlothar take Autun after a long siege, then in 534, with Theudebert (Theuderic’s son), finish the conquest and partition Burgundy. Vézeronce is thus a decisive pause, not the end of Burgundian independence — a point underlined by the kingdom’s decade of survival after the battle.
