Learning that Ariovistus intended to seize Vesontio, the largest Sequani town, Caesar began marching his troops toward it. Some of his officers held their posts for political reasons only and had no war experience. Consequently, they suffered from poor morale, which threatened Caesar's campaign. He challenged the officers and their legions, saying that the only legion he could trust was the 10th. With their pride on the line, the other legions followed the 10th's lead, determined not to be outdone. Consequently, Caesar arrived in Vesontio before Ariovistus.
