a time it seemed as though the Romans would be driven from the country. But Cæsar's despatch and military genius saved the province to the republic.
In his campaigns in Gaul, Cæsar had subjugated three hundred tribes, captured eight hundred cities, and slain a million of barbarians—one third of the entire population of the country. Another third he had taken prisoners. Great enthusiasm was aroused at Rome by these victories. "Let the Alps now sink," exclaimed Cicero: "the gods raised them to shelter Italy from the barbarians: they are now no longer needed."
