move off by the difficult route down the right bank of the Rhone. This accomplished, Cæsar hastened back to Italy, got five legions together, led them over the Cottian Alps, crossed the Rhone above Lyons, and caught up with the Helvetii before the last of their cumbrous train had got beyond the Saone. Attacking and cutting to pieces this rear-guard (it was the tribe of the Tigurini, which the Romans had encountered disastrously half a century before), he bridged the Saone and crossed it to pursue the main body of the enemy. For many days he followed them, refusing to give battle to the great barbarian army until he saw the moment opportune. His blow was struck at last in the neighborhood of the city of Bibracte, the capital of the Ædui—modern Autun. The defeat of the Helvetii was complete, and, although a great body of them escaped, they were set upon by the Gauls of the country and were soon glad to surrender themselves unconditionally to the Roman proconsul. Cæsar compelled them—110,000 survivors, of the 368,000 who left Switzerland in the spring—to go back to their mountains and rebuild and reoccupy the homes they had destroyed. _C.
