Lucius Cassius Longinus
In 107 BC, the Roman Senate launched another campaign under Lucius Cassius Longinus, Lucius Caesoninus, and Gaius Popillius Laenas (son of Publius Popillius Laenas), to defend one of their allied tribes. At first, all went well for Rome. Just outside Tolosa, the combatants met and, despite the huge numbers of Germans and their allies, Longinus defeated them and they retreated in disorder, leaving behind a large number of baggage wagons. Flushed with his success, Longinus followed them, but was reluctant to leave behind the captured baggage train, which slowed his army down significantly.
