Events

A coalition of Cisalpine Gallic tribes (Taurini, Taurisces, Insubres, Lingones, Salasses, Agones, and Boii), reinforced by large numbers of Transalpine adventurers called Gaesatae (Gaesati), invade Italy. Avoiding the Romans at Ariminum, the Gauls cross the Apennines into Etruria, plunder the country.
To meet this invasion, the Romans call on the Insubres' enemies, the Adriatic Veneti, the Patavini, and the Cenomani, who rapidly mobilise defensive forces. These armies are placed under the command of consuls Lucius Aemilius Papus and Gaius Atilius Regulus. After the Battle of Faesulae (near Montepulciano) between the Gauls and a Roman army in which the Romans lose many men, the combined Roman forces succeed in outmaneuvering the Gauls and force the invaders towards the coast of Tuscany.

Seleucus III takes up the task of reconquering Pergamum in Anatolia from Attalus. However, Andromachus, the first general whom he sends, is decisively defeated and captured by Attalus.
