Instead, the Romans split their forces. The consul Marcus Claudius Marcellus headed for Clastidium and his colleague Gnaeus Cornelius Scipio Calvus continued the siege of Acerrae. At the Battle of Clastidium, Marcus Claudius defeated the Gallic forces and killed Viridomarus in single combat. Meanwhile, Gnaeus Cornelius took Acerrae. With the fortress taken and the Insubre king dead, the Romans then easily took the capital of the Insubres, which they named Mediolanum (Milan).
