⚔️🔒Battle of the Catalaunian Fields, France, ~20 June 451 AD

The decisive battle for the Western world!

First, a disclaimer: I cannot claim with absolute certainty to have explored the precise site of the 451 AD Battle of the Catalaunian Fields — also known as the Battle of the Catalaunian Plains. Although it was one of the truly decisive battles in history, contemporary sources are scarce. Our main account comes from Jordanes, a Byzantine Goth who wrote Getica around 551 AD, chronicling the history of the Gothic peoples.

Jordanes described the battlefield in some detail, placing it near the Catalaunian Plains, in the region of Châlons-en-Champagne or Troyes, in eastern France. Other writers of the period offer important corroborating clues. However, for the past 1500+ years the exact location of the battle has been the subject of much debate. I will discuss this further in ‘The battlefield today’ segment.

🧭🥾 Walking the Battlefield

I have been fortunate to visit several of the proposed sites for the Battle of the Catalaunian Fields. The first time was in June 2012 and the second was in November 2024. There are several sound theories about where the battle took place, but as I delved deeper, I became convinced that the site near Troyes was the most likely. Contemporary and near-contemporary sources described the location in sufficient detail, and the region’s folk memory and place names provide compelling evidence. When I walked the battlefield, I was armed with numerous Roman and Gothic accounts, 19th and 20th-century historical studies, maps, diagrams, and a detailed GIS analysis.

By 451 AD, the Roman Empire was in serious decline. The 3rd Century AD had been wracked by Civil War (235-285 AD) and leadership turmoil (assassinations, coups, feeble emperors, infant emperors, etc). From around 376 AD, hundreds of thousands of Goths and other tribal groups from the Black Sea area began massing on the north side of the Danube, seeking sanctuary within the empire.

These migrations were driven by a new terror from the steppe — the Huns, who were devastating the plains of what is now southern Russia and Ukraine. Roman knowledge of the Huns came mostly from the refugees’ horrific stories of savagery and pillage. In 377 AD, the Goths were permitted to cross the Danube, but thanks to clumsy diplomacy and corrupt Roman administration, they rebelled, crushed the Eastern Roman field army, and killed Emperor Valens at the disastrous Battle of Adrianople (now Edirna, Turkey) in 378 AD.

Valens’ successor, Theodosius the Great, was the last Emperor to rule a unified empire. Upon his death in 395 AD, the Roman Empire was formally split in two, with the West ruled by Emperor Arcadius from his capital in Ravenna, Italy, and the East ruled by Emperor Honorius from his capital in Constantinople (modern Istanbul). At about the same time, the Eastern Roman Empire first came into direct contact with the Huns.

Origins and rise of the Huns

The Huns likely originated in Central Asia, perhaps the same confederation known to the Chinese as the Xiongnu who harried northern China from the 3rd century BC to the 2nd century AD. Driven westward by successive Chinese campaigns, they absorbed or allied with other tribes, arriving in Europe as a federation of ethnic Huns, conquered steppe peoples, and Germanic tribes.

The Hunnic empire

By the early 5th Century, the Hunnic empire was centred in the Hungarian Plain and covered most of what is now Hungary, Germany, Romania, Poland, Ukraine, Belarus and European Russia. In their weakened state, the Romans eventually adapted to having a large rival empire as their neighbour across the Danube. At various times during the early 5th century, the Huns allied with, or fought against, both the Eastern and Western Roman Empires. The Romans also had no problem employing Hun mercenaries in Roman armies to defeat other enemies.

Throughout the 420s and 430s, under their King Rugila, the Huns regularly crossed into the Eastern Roman Empire, sacking towns, looting, and laying waste to the region south of the Danube (today’s Serbia, Bulgaria, Greece). Rugila died in ~435 AD and was succeeded by his two nephews, Bleda and Attila. Bleda died in 445, probably murdered, and Attila became the sole King of the Hunnic Empire. Attila inflicted a major defeat on the Eastern Roman Empire at the Battle of the Utus River in 447 AD, and was only stopped by the massive defences of Constantinople.

Contemporary writers offer several reasons for Attila’s next move against the Western Roman Empire. With much of the Balkans devastated by previous Hun raiding, Attila now coveted the more prosperous province of Gaul (modern France). Around 449 AD, the Frankish (northern France) King Chlodio died, and there was a succession struggle between his two sons. The younger son was under the care of Roman General Flavius Aetius, and Rome supported his claim. The older son sought support for his claim from Attila and the Huns. At about the same time, Honoria, the sister of Western Roman Emperor Valentinian III, apparently made an offer to marry Attila, with an implication that the dowry would include half the western empire. Either or both of these provocations provided Attila with his casus belli.

Sack of Metz

In early 451 AD, Attila and an enormous force of Huns, with allied Ostrogths, Gepids, Thuringii, Franks, and Burgundians crossed into Roman Gaul. The Huns sacked Divodurum (Metz) and several other cities in eastern Gaul. Emperor Valentian tasked Roman General Flavius Aetius to raise a force to halt the Hunnic invasion.

Romans and Visigoths – an unnatural alliance

Aetius had lived for years as a hostage of the Huns, and had led armies of Hunnic mercenaries against rebellious tribes in Gaul, so he knew the Huns and Attila very well. He took with him a core element of Roman regular troops, gathered Roman border troops and garrison troops along the way, and was able to negotiate an unlikely alliance with traditional enemy Theodoric, King of the Visigoths. Contingents of Alans, Franks, Burgundians, and others also joined his coalition against the Huns.

Attila halted at Orleans

After sacking Metz, the Hun army next moved against the Alan-held city of Aurelianorum (Orleans). Aetius got there first with his Roman-Visigothic force and prevented the Huns from laying siege. Attila had not expected to face a combined force of Romans, Visigoths, and other traditional enemies. He was forced to consider withdrawal.

“Then Attila, king of the Huns, was taken aback by this event [the intervention of the Romano-Visigothic forces] and lost confidence in his own troops, so that he feared to begin the conflict. While he was meditating on flight—a greater calamity than death itself—he decided to inquire into the future through soothsayers.”

Jordanes 551 AD

The improbable alliance between Rome and the Visigoths changed the calculus for Attila and he began withdrawing westwards via the Roman roads through Sens and on to Troyes.
