The consul Publius Cornelius Dolabella advanced with a strong army into their territory; all that were not put to the sword were driven forth from the land, and this tribe was erased from the list of the Italian nations (471).

In the case of a people subsisting chiefly on its flocks and herds such an expulsion en masse was quite practicable; and the Senones thus expelled from Italy probably helped to make up the Gallic hosts which soon after inundated the countries of the Danube, Macedonia, Greece, and Asia Minor.
The Boii The next neighbours and kinsmen of the Senones, the Boii, terrified and exasperated by a catastrophe which had been accomplished with so fearful a rapidity, united instantaneously with the Etruscans, who still continued the war, and whose Senonian mercenaries now fought against the Romans no longer as hirelings, but as desperate avengers of their native land.

A powerful Etrusco-Gallic army marched against Rome to retaliate the annihilation of the Senonian tribe on the enemy's capital, and to extirpate Rome from the face of the earth more completely than had been formerly done by the chieftain of these same Senones.

But the combined army was decidedly defeated by the Romans at its passage of the Tiber in the neighbourhood of the Vadimonian lake (471).

After they had once more in the following year risked a general engagement near Populonia with no better success, the Boii deserted their confederates and concluded a peace on their own account with the Romans (472).
