Indutiomarus

Indutiomarus (d. 53 BCE) was a leading aristocrat of the Treveri (the people of the area around present-day Trier) at the time of Caesar's conquest of Gaul. He was the head of the anti-Roman party and political rival of his pro-Roman son-in-law Cingetorix for "supreme power" in the state. [C. Julius Caesar. "De Bello Gallico:" .]

In 54 BCE, Indutiomarus made preparations for war against the Romans and evacuated non-combatants to the Ardennes. However, when Caesar arrived in the territory of the Treviri en route to Britain, Indutiomarus was deserted by many of his leading supporters and sub­mitted to Caesar in the hopes of preserving his position. Caesar accepted his submission, along with 200 hostages including several of Indutiomarus' close family members, but he also took the opportunity to promote Cingetorix to power among the Treveri at Indutiomarus' expense. ["Op. cit." .]

Deprived of much of his power, Indu­tiomarus became all the more bitter an enemy of the Romans, and waited for a favourable oppor­tunity to take his revenge. Such an opportunity arrived soon. To ensure adequate food supplies, Caesar had separated his troops into winter quarters dispersed in different parts of Gaul. Indutio­marus encouraged Ambiorix and Cativolcus, chiefs of the Eburones, to attack the Roman legion stationed in their country; he himself soon afterwards marched against Titus Labienus, who was encamped among the Remi, immediately west of the Treveri. Forewarned of Caesar's victory over the Nervii, Indutiomarus withdrew his forces into Treveran country and raised fresh troops. He also spent the winter sending ambassadors to the Germans in search of allies. Other peoples began sending ambassadors to Indutiomarus of their own accord as well – these included the Senones, the Carnutes, the Nervii and the Aduatuci. ["Op. cit." .]

Now emboldened, Indutiomarus declared Cingetorix an enemy of the state and confiscated his property.He marched against Labienus again and surrounded the Roman camp. Indutiomarus took to riding around the camp with his cavalry force almost daily, both to reconnoitre and to intimidate the Romans within. Labienus one day sneaked a large contingent of auxiliary cavalry into the Roman camp, and during one of these exercises the auxiliaries surprised the Treveran force with a sudden sally. Indutiomarus himself was killed in the rout while crossing a river. ["Op. cit." .] His death was still a source of anger and rebellion as of 51 BCE, when the Treveri remained in the field on the side of Ambiorix. [Cassius Dio. "Roman History."
