Battle of the Teutoburg Forest

• 1. Introduction

  ›

  The Battle of the Teutoburg Forest began with a payday. On the morning of the 7th of September, 9 CE, the Roman army mustered to move out, and the muster was combined with the third payday of the year. Coins were distributed in large quantities across the ranks. Those coins, buried under centuries of soil, would eventually lead a British amateur archaeologist named Tony Clunn to the battlefield nearly two thousand years later, in 1987.

  The catastrophe that followed those payouts is known to Roman historians as the Clades Variana, the Varian Disaster. Three Roman legions, their auxiliaries, and the civilians who followed them were ambushed and destroyed by a Germanic coalition in terrain so dense and hostile that the Roman army never had a chance to fight on its own terms. The man responsible for that destruction was someone the Roman general Publius Quinctilius Varus considered a trusted friend.

  The questions the Teutoburg disaster raises reach far beyond a single battle: How did one man deceive an entire empire? Why did Rome never cross the Rhine in force again? And what did a Germanic victory in the forests of northern Europe mean for the shape of the world that followed?

  Arminius was born into the Cherusci tribe, but he grew up in Rome. After Drusus defeated the Cherusci in 8 BCE, Arminius was taken hostage at roughly ten years old, and he received an aristocratic education befitting his status as the son of a nobleman. He rose through Roman ranks to join the ordo equester, the cavalry, and by 4 CE he was serving in Pannonia, in the northwestern Balkan states.

  Historian Michael McNally argues that two specific events shaped how Arminius came to see Rome. In 11 BCE, the Cherusci had trapped a Roman army in unfavourable terrain, nearly destroying it; in 8 BCE, Rome crushed the tribe, and Arminius himself was taken as a consequence. From these two episodes McNally draws out a conclusion Arminius reached: the Romans could be beaten, but only where their tactical flexibility and discipline could not come into play.

  When Arminius returned to Germania, he was nominally loyal to Rome. He took a position as a commander of Roman auxiliaries and became a trusted advisor to Varus himself. Beneath that surface, he was quietly assembling a coalition of tribes that had long been rivals. These probably included the Cherusci, Marsi, Chatti, and Bructeri, drawn from roughly fifty Germanic tribes of the era. The glue binding them was collective outrage at Varus's conduct: his cruelty, his insolence, and what the source describes as his tyranny toward the conquered.

• 3. Varus and His Command

  ›

  Publius Quinctilius Varus was not sent to Germania for his military skill. Emperor Augustus appointed him quaestor at an unusually young age in 22 BCE, normally a post requiring at least thirty years of age. He later commanded the XIX legion, served as governor of Africa in 8 BCE and Syria in 7 BCE, and then married the Emperor's great-niece after his term ended, which secured him a place in Augustus's inner circle. According to Michael McNally, his value in Germania was political, not martial; Augustus needed someone who could manage the factional tensions among the Germanic tribes.

  Varus's reputation among the conquered peoples was fearsome. His use of crucifixion against insurgents made his name known far beyond the empire's borders. The Roman Senate held him in high regard, but the people he governed did not. On the Rhine, he commanded the XVII, XVIII, and XIX legions, inherited from General Gaius Sentius Saturninus.

  His initial force in Germania was around twenty-five thousand soldiers, not counting auxiliaries, representing roughly twenty percent of Rome's frontline army. By the time of the battle, only three of his original five legions were with him, perhaps fifteen thousand men, supported by nine small auxiliary units. Accounting for winter attrition, illness, and detached garrisons, McNally estimates the force at approximately seventeen thousand combatants and a few thousand more non-combatants. The army that marched into the forest was already smaller than the one that had begun the year.

• 4. The Trap Is Set

  Arminius spent the summer of 9 CE performing two roles simultaneously. As Varus's advisor he attended court, observed logistics, and embedded his own Cherusci auxiliaries within the Roman column. As the architect of the ambush he ordered allied tribes to start raiding Roman positions in July, then counselled Varus to split off a detachment to suppress the unrest. Varus complied, fracturing his own forces.

  Varus's father-in-law Segestes warned him directly that Arminius was planning treachery. Varus dismissed the report, likely because Segestes had disapproved of his daughter's marriage to Arminius and appeared to have a personal grudge. The warning went nowhere.

  As late summer arrived, Arminius fabricated reports of a local rebellion west of the River Weser, on the route Varus needed to travel to reach winter quarters. The historian Edward Shepherd Creasy wrote that Varus "was kept in studied ignorance of its being part of a concerted national rising; and he still looked on Arminius as his submissive vassal." An adviser urged early retreat along the well-guarded route the army had already traveled, which would have collapsed Arminius's plans entirely. Instead, Arminius suggested a shorter alternative route through Angrivarii territory that would let the army suppress the revolt and still reach winter camp. Varus chose that path.

  On the evening of September 7, Arminius told Varus he was leaving to finish mustering the Cherusci auxiliaries. It was the two men's final meeting. Arminius left behind a handful of Cherusci nominally as guides; their real role was to spy. His departure stripped the Roman column of a quarter of its strength and most of its scouting capability.

  On the morning of September 8, the Roman column moved out and began threading through dense forest. The Bructeri allies of Arminius attacked along the full length of the march in late morning, when the line had stretched to between fifteen and twenty kilometres. Germanic warriors armed with swords, large lances, and narrow-bladed short spears called fremae surrounded the Romans and rained javelins down on them. The attack was brief, calibrated to exhaust the soldiers and destroy supplies rather than force a decisive engagement. The Bructeri withdrew, taking the embedded Cherusci spies with them.

  A torrential downpour then made further advance impossible. Varus ordered the army to make camp, erected a sturdy fortified position, and held a war council. Casualty reports showed only light losses, but the baggage trains and scout cavalry had taken heavy damage.

  The Romans attempted a night march to escape, and marched into another trap. At the foot of Kalkriese Hill, a sandy open corridor no more than about one hundred metres wide ran between the hill and the swampland at the edge of what was called the Great Bog. Arminius had prepared well: a trench blocked the road, and an earthen wall had been constructed along the forest edge, giving the Germanic alliance cover from which to attack. The Romans stormed the wall and failed. Legatus Numonius Vala, the highest-ranking officer beneath Varus, broke and fled with the cavalry. According to Velleius Paterculus, he was overtaken by Germanic horsemen and killed shortly after. Varus committed suicide. Praefectus Ceionius surrendered, then later took his own life. Praefectus Eggius died leading his troops. Roman casualties have been estimated at fifteen thousand to twenty thousand dead.

  For almost two thousand years, the site of the battle was unidentified. The main textual clue was a reference in Tacitus's Annals to a place called the saltus Teutoburgiensis, described as lying not far from the land between the upper reaches of the Lippe and Ems rivers in central Westphalia. During the 19th century the followers of one theory successfully argued for a long wooded ridge called the Osning, near Bielefeld, which was then renamed the Teutoburg Forest.

  The modern identification began with a metal detector. In 1987, Major Tony Clunn, a British amateur archaeologist, was casually prospecting at Kalkriese Hill hoping, as the source records, to find "the odd Roman coin." He discovered coins from the reign of Augustus and none from any later period, along with ovoid leaden Roman sling bolts. Kalkriese is a village on the north slope of the Wiehen hills in Lower Saxony, about a hundred kilometres northwest of the Osning. Initial systematic excavations were led by Professor Wolfgang Schlüter's team from the Kulturhistorisches Museum Osnabrück beginning that same year; since 1990 the excavations have been directed by Susanne Wilbers-Rost.

  Excavations revealed battle debris along a corridor almost twenty-four kilometres long and little more than a mile wide. A long zig-zagging wall of peat turves and packed sand had been built before the battle; concentrations of debris in front of it and near-nothing behind it confirm the Romans never broke through. Excavators found six thousand pieces of Roman equipment. Only a single clearly Germanic item turned up: part of a spur. Coins countermarked VAR, distributed by Varus himself, were found at the site. Among the artefacts now housed in the museum are fragments of legionaries' studded sandals, spearheads, and a Roman officer's ceremonial face-mask that was once silver-plated.

• 7. Rome Strikes Back

  ›

  The first Roman response came in 14 AD, just after Augustus died, when the new emperor Tiberius's nephew Germanicus launched a massive raid against the Marsi. The Bructeri, Tubanti, and Usipeti retaliated by ambushing Germanicus on his return march, but were defeated with heavy losses.

  The following year brought two major campaigns. Legatus Caecina Severus invaded the Marsi again with around twenty-five thousand to thirty thousand men. Germanicus separately built a fort on Mount Taunus, then marched a force of about thirty thousand to thirty-five thousand men against the Chatti, burning their capital Mattium to the ground. His troops captured Arminius's wife Thusnelda. At a site Tacitus calls the pontes longi, meaning the long causeways, Arminius sprang another trap, catching Germanicus's cavalry and inflicting heavy casualties before Roman infantry halted the attack. After two days without a decisive result, the Romans withdrew to the Rhine.

  In 16 AD, Germanicus forced a crossing of the Weser near modern Minden and compelled Arminius to stand in open battle at Idistaviso, in what became the Battle of the Weser River. The Germanic forces suffered huge casualties. A final engagement at the Angrivarian Wall west of modern Hanover again resulted in heavy Germanic losses. Tiberius then recalled Germanicus to Rome and awarded him a triumph. Tacitus, with some bitterness, suggests Tiberius was motivated partly by jealousy of the glory Germanicus had earned.

  The last of the three lost legionary eagles was recovered in 41 AD by Publius Gabinius from the Chauci, during the reign of Claudius. Arminius himself was poisoned in 21 AD, possibly by members of his own family who feared his growing autocratic power.

• 8. The Longer Shadow

  Rome's decision to treat the Rhine as a permanent border was shaped by factors beyond the battlefield. Armies on the Rhine could be supplied from the Mediterranean through the Rhône, Saône, and Mosel rivers with only a short overland stretch. Armies pushed to the Elbe would have needed either long overland supply chains or ships navigating dangerous Atlantic waters. Northern Germania also offered far less economic return: fewer towns, smaller food surpluses, and limited capacity to generate tribute. Southern Gaul was already woven into Roman trade networks; Germania Magna was not.

  The formal Roman provinces of Germania Inferior, with its capital at Colonia Claudia Ara Agrippinensium (modern Cologne), and Germania Superior, with its capital at Mogontiacum (modern Mainz), were established in 85 AD after a long period of military occupation. Recent archaeology has complicated the simple narrative of permanent Roman retreat: excavations at a Varian-era Roman provincial settlement at Waldgirmes Forum suggest Varus had already begun full colonisation of a greater German province before the disaster struck.

  The legacy of the battle was recovered in the 15th century when Tacitus's works were rediscovered. The Germanic chieftain Arminius was recast as "Hermann," a name derived from a mistranslation of "Armin," and became a symbol of German national identity. A monument to Hermann, the Hermannsdenkmal, was begun in 1841 near Detmold, on the summit of Grotenburg. It was completed only in 1875, after the Franco-Prussian War had unified Germany. The statue atop it faced west, toward France.
