Lucius Caecilius Metellus
According to Polybius, unspecified Gauls besieged the city of Arretium (Arezzo, in northeastern Tuscany) and defeated a Roman force which had come to the aid of the city. Their commander, the praetor Lucius Caecilius Metellus Denter, died in the battle. This would place the battle in 283 BC because Denter was a consul in 284 BC.
