in his firsthand account, De Bello Gallico, as the "largest and the most warlike nation of all the Germans". Caesar confronted a large army led by a Suevic King named Ariovistus in 58 BC who had been settled for some time in Gaul already, at the invitation of the Gaulish Arverni and Sequani as part of their war against the Aedui. He had already been recognized as a king by the Roman senate. Ariovistus forbade the Romans from entering into Gaul. Caesar on the other hand saw himself and Rome as an ally and defender of the Aedui. The forces Caesar faced in battle were composed of "Harudes, Marcomanni, Tribocci, Vangiones, Nemetes, Sedusii, and Suevi". While Caesar was preparing for conflict, a new force of Suebi was led to the Rhine by two brothers, Nasuas and Cimberius, forcing Caesar to rush in order to try to avoid the joining of forces. Caesar defeated Ariovistus in battle, forcing him to escape across the Rhine. When news of this spread, the fresh Suebian forces turned back in some panic, which led local tribes on the Rhine to take advantage of the situation and attack them. Caesar and the Suebi in 55 BC Also reported within Caesar's accounts of the Gallic wars, the Suebi posed another threat in 55 BC. The Germanic Ubii, who had worked out an alliance with Caesar, were complaining of being harassed by the Suebi, and the Tencteri and Usipetes, already forced from their homes, tried to cross the Rhine and enter Gaul by force. Caesar bridged the Rhine, the first known to do so, with a pile bridge, which though considered a marvel, was dismantled after only eighteen days. The Suebi abandoned their towns closest to the Romans, retreated to the forest and assembled an army. Caesar moved back across the bridge and broke it down, stating that he had achieved his objective of warning the Suebi. They in turn supposedly stopped harassing the Ubii. The Ubii were later resettled on the west bank of the Rhine, in Roman territory. Rhine crossing of 29 BC Cassius Dio (c. 150 – 235 AD) wrote the history of Rome for a Greek audience. He reported that, shortly before 29 BC, the Suebi crossed the Rhine, only to be defeated by Gaius Carrinas who, along with the young Octavian Caesar, celebrated a triumph in 29 BC. Shortly after, they turn up
