The struggle was obstinate, and not without moments of anxiety and partial check for the Romans; but the genius of Caesar and strict discipline of the legions carried the day.

The rout of the Germans was complete; they fled towards the Rhine, which was only a few leagues from the field of battle.

Ariovistus himself was amongst the fugitives; he found a boat by the river side, and recrossed into Germany, where he died shortly afterwards, "to the great grief of the Germans," says Caesar.
The Suevian bands, who were awaiting on the right bank the result of the struggle, plunged back again within their own territory.

And so the invasion of the Germans was stopped as the emigration of the Helvetians had been; and Caesar had only to conquer Gaul.
It is uncertain whether he had from the very first determined the whole plan; but so soon as he set seriously to work, he felt all the difficulties.

The expulsion of the Helvetian emigrants and of the German invaders left the Romans and Gauls alone face to face; and from that moment the Romans were, in the eyes of the Gauls, foreigners, conquerors, oppressors.
