The Cimbrian War or Cimbric War (113-101 BC) was fought between the Roman Republic and the Germanic and Celtic tribes of the Cimbri and the Teutones, Ambrones and Tigurini, who migrated from the Jutland peninsula into Roman controlled territory, and clashed with Rome and her allies. The Cimbrian War was the first time since the Second Punic War that Italia and Rome itself had been seriously threatened.
The timing of the war had a great effect on the internal politics of Rome, and the organization of its military. The war contributed greatly to the political career of Gaius Marius, whose consulships and political conflicts challenged many of the Roman Republic’s political institutions and customs of the time. The Cimbrian threat, along with the Jugurthine War, inspired the landmark Marian reforms of the Roman legions.
Rome was finally victorious, and its Germanic adversaries, who had inflicted on the Roman armies the heaviest losses that they had suffered since the Second Punic War, with victories at the battles of Arausio and Noreia, were left almost completely annihilated after Roman victories at Aquae Sextiae and Vercellae. Some of the surviving captives are reported to have been among the rebelling gladiators during the Third Servile War.
Migrations and Conflicts
According to some Roman accounts, sometime around 120-115 BC, the Cimbri left their original lands around the North Sea due to flooding (Strabo on the other hand, wrote that this was unlikely or impossible). They supposedly journeyed to the south-east and were soon joined by their neighbours and possible relatives the Teutones. Together they defeated the Scordisci, along with the Boii, many of whom apparently joined them. In 113 BC they arrived on the Danube, in Noricum, home to the Roman-allied Taurisci. Unable to hold back these new, powerful invaders on their own, the Taurisci called on Rome for aid.
Initial Roman Defeats
The following year the Roman consul Gnaeus Papirius Carbo led the legions into Noricum, and after making an impressive show of force, took up a strong defensive position and demanded that the Cimbri and their allies leave the province immediately. The Cimbri initially set about complying peacefully with Rome’s demands, but soon discovered that Carbo had laid an ambush against them. Infuriated by this treachery, they attacked and, at the Battle of Noreia, annihilated Carbo’s army, almost killing Carbo in the process.
Italy was now open to invasion, yet for some reason, the Cimbri and their allies moved west over the Alps and into Gaul. In 109 BC, they invaded the Roman province of Gallia Narbonensis and defeated the Roman army there under Marcus Junius Silanus. In 107 BC, the Romans were defeated again, this time by the Tigurini, who were allies of the Cimbri whom they had met on their way through the Alps. That same year, they defeated another Roman army at the Battle of Burdigala (modern day Bordeaux) and killed its commander, the consul Lucius Cassius Longinus Ravalla.
Disaster at Arausio
In 105 BC, Rome and its new consul Gnaeus Mallius Maximus and the proconsul Quintus Servilius Caepio, in order to settle the matter once and for all, gathered the largest force it had fielded since the Second Punic War, and possibly the largest force it had ever sent to battle. The force consisted of over 80,000 men, along with tens of thousands of support personnel and camp followers in two armies, one led by each consul.
The consuls led their armies on their own armed migration to the Rhône River near Orange, Vaucluse, where, disliking and distrusting each other, they erected separate camps on opposite sides of the river; by so doing they left their disunited force open to separate attack. The overconfident Caepio foolishly attacked without support from Maximus; his legions were wiped out and his undefended camp overrun. The now isolated and demoralised troops of Maximus were then easily defeated. Thousands more were slain trying desperately to rally and defend his poorly positioned camp. Only Caepio, Maximus, and a few hundred Romans escaped with their lives across the carnage-choked river. The Battle of Arausio was the costliest defeat Rome had suffered since Cannae and, in fact, the losses and long-term consequences were far greater. For the Cimbri and Teutones it was a great (though temporary) triumph.
Instead of immediately gathering their allies and marching on Rome, the Cimbri proceeded to Hispania. There, they suffered their first defeat, not at the hands of a Roman army, but against a Celtiberian coalition. In the meantime, the Teutones remained in Gaul. Why they again failed to invade Italy remains a mystery.
Marius takes Command
Following the devastation of the Arausio, fear shook the Roman Republic to its foundations. The terror cimbricus became a watchword, as Rome expected the Cimbri at its gates at any time. In this atmosphere of panic and desperation, an emergency was declared. The constitution was ignored and Gaius Marius, the victor over Jugurtha of Numidia was elected consul for an unprecedented, and arguably illegal, five years in a row, starting in 104 BC. Because of the destruction of the Roman force at Arausio and the pressure of the impending crisis, Marius was now given the latitude to construct a new army on his own terms.
Until now, the army had been a well-trained, well-regulated militia drawn from all able-bodied, land-owning male citizens. Marius replaced this with a professional standing force composed mostly of able-bodied but landless volunteers. He improved and standardised training, weapons, armour, equipment, and command structure, and made the cohort the main tactical and administrative unit of the legion. Along with these new arrangements came new standards and symbols, such as the aquila, which the troops came to revere and which was almost never allowed to fall into enemy hands.
While the panicked Senate and people of Rome gave Marius the power he needed to build his army, the failure of the Cimbri and Teutones to follow up on their victory gave him the time he needed to finish it. They would soon be confronted by an army of organised, highly trained, professional soldiers under the leadership of a brilliant and ruthless commander.
Turning Point of the War
By 102 BC, Marius was ready to face the Cimbri; the latter, after difficulties in Spain, had turned north into Gaul, where they were joined by the Teutons, a Germanic tribe apparently from north-Germany or Denmark. After this union, the Germanic coalition determined to move back south upon Italy, which they had previously avoided. Marching south through Switzerland and Savoy, their army was augmented by some tribes of Helvetians, particularly the Tigurini, and the Ambrones of uncertain descent.
Before approaching Italy, the Germans decided on a two pronged movement; the Teutons with the Ambrones and the Tigurini would move from the west along the coast-road from Transalpine into Cisalpine Gaul; while the Cimbri would march east and turn around into Italy by the Julian and Carnic Alps. When Marius heard of their movements, he advanced to Valence, and established his camp at the confluence of the Isère and the Rhône, where he could observe and halt the march of the Teutons. When the Teutons arrived, they attempted to force him into battle, but he declined; they attacked the Roman camp, but were beaten off.
Impatient of the delay and of Marius’ passivity, they finally decided to simply march past him into Italy. So enormous were their numbers, that they reportedly took six (6) whole days marching by his camp, and in their arrogance they taunted the Romans, what message they wished them to give to their wives? Marius followed cautiously, maintaining distance from the enemy, but closely following his movements. A few days later, a skirmish turned into a battle with the Ambrones, who for some reason camped separately from the Teutones. The Ambrones were defeated with heavy losses and fled to their Teutonic allies. The Teutones halted their trek south and awaited Marius near Aquae Sextiae.
This afforded Marius favourable conditions, for with his enemy stationary he got to scout the battlegrounds and he chose his ground carefully. In the subsequent battle, he lured the Teutones and their allies into attacking him while his army was occupying the highground. During their attack they were ambushed from the rear by a select force of five cohorts which Marius had hidden in a nearby wood. The Teutones were routed and massacred and their king, Teutobod, was placed in Roman chains. But Aquae Sextiae had only evened the score: while the Teutones had been eliminated, the Cimbri remained a formidable threat.
In 101 BC, the Cimbri returned to Gaul and prepared for the final stage of their struggle with Rome. For the first time they penetrated through the Alpine passes, which Marius’s co-consul for that year, Quintus Lutatius Catulus, had failed to fortify, into northern Italy. Catulus withdrew behind the Po River, leaving the countryside open to the invaders. But the Cimbri took their time ravishing the fertile region, which gave Marius time to arrive with reinforcements – his same victorious legions from Aquae Sextiae. It would be at Vercellae near the confluence of the Sesia River with the Po on the Raudine Plain where the superiority of the new Roman legions and their cavalry were clearly demonstrated. In the devastating defeat the Cimbri were virtually annihilated, and both their highest leaders, Boiorix and Lugius, fell. The women killed both themselves and their children in order to avoid slavery. Thus the war, which began with a mass migration, ended in defeat and mass suicide.
Aftermath and Legacy
The Cimbri were not completely wiped off the face of the map or from the pages of history. Their allies, the Boii, with whom they intermixed, settled in southern Gaul and Germania and were there to welcome and confront Julius Caesar, Marius’s nephew, in his campaigns of conquest. Some of the surviving captives are reported to have been among the rebelling gladiators in the Third Servile War.
The political consequences from the war had an immediate and lasting impact on Rome. The end of the Cimbrian war marked the beginning of the rivalry between Marius and Sulla, which eventually led to the first of Rome’s great civil wars. Moreover, following the final victory at Vercellae, and without first asking permission from the Senate, Marius granted Roman citizenship to his Italian allied soldiers, claiming that in the din of battle he could not distinguish between the voices of Romans and the Italic allies. Henceforth all Italian legions became Roman legions and the allied cities of the Italian peninsula progressively began to demand a greater say in the external policy of the Republic, leading eventually to the Social War.
