sent envoys to them to complain of their furnishing warriors to serve against Rome, and to require the surrender of their captives without ransom.  But by the command of their chieftain Britomaris, who had to take vengeance on the Romans for the death of his father, the Senones slew the Roman envoys and openly took the Etruscan side.  All the north of Italy, Etruscans, Umbrians, Gauls, were thus in arms against Rome; great results might be achieved, if its southern provinces also should seize the moment and declare, so far as they had not already done so, against Rome.  In fact the Samnites, ever ready to make a stand on behalf of liberty, appear to have declared war against the Romans; but weakened and hemmed in on all sides as they were, they could be of little service to the league; and Tarentum manifested its wonted delay.  While her antagonists were negotiating alliances, settling treaties as to subsidies, and collecting mercenaries, Rome was acting.  The Senones were first made to feel how dangerous it was to gain a victory over the Romans.  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).  Thus the Gauls, the most formidable member of the league, were conquered in detail before the league was fully formed, and by that means the hands of Rome were left free to act against Lower Italy, where during the years 469-471 the contest had not been carried on with any vigour.  Hitherto the weak Roman army had with difficulty maintained itself in Thurii against the Lucanians and Bruttians; but
