One of the most legendary legions in the history of the Roman military was the Legio-Nonem Hispana,
or the ninth Spanish Legion.
They served under Poppy the Great, and later with Julius Caesar and Gaul.
They served Emperor Augustus and were pivotal in the conquest of Britain under the Emperor Claudius.
And then, at some point, they simply disappeared.
There was never a mention of them again in the historical record.
And for almost 2,000 years, it's been one of the world's greatest historical mysteries.
Learn more about the missing legion,
and what might have happened to them on this episode of Everything Everywhere Daily.

In a previous episode, I covered how Roman armies worked. The base unit of the Roman military was
the Legion. A Roman Legion typically consisted of about 5 to 6,000 soldiers. The number could vary
based on the Legion, the circumstances in the period in history, but 5 to 6,000 was the historical
average. In addition to the core infantry forces, a Legion also included support personnel,
such as engineers, clerks, medics, blacksmiths, and animal handlers, as well as a small cavalry
unit. When auxiliaries, who are non-citizen troops attached to the legions were included,
the total fighting force associated with the Legion could exceed 10,000 men. And on top of that,
estimates suggest that for every legionary soldier, there may have been at least one and possibly
as many as two civilians. The civilians may have included legionaire's unofficial wives or concubines,
children, merchants, prostitutes, and even slaves. Legions were initially raised from
Roman citizens during the Republican period and later became full-time professional.
armies. Throughout history, legions would be raised and occasionally disbanded. Three legions were disbanded
for cowardice after the Batavi revolt in the year 70. The 17th, 18th, and 19th legions were wiped out in the
Battle of Tudorburg Forest, and those numbers were never used again. Most legions existed for decades,
if not centuries. Over time, they developed distinct identities that went beyond their functions as
mere military units, evolving into institutions with deep cultural significance, proud traditions,
and fiercely guarded reputations. Each legion developed its personality through the accumulation
of battle honors, the cultivation of specific traditions, and the development of distinctive customs
that set it apart from other legions. This process began from the moment of formation and continued
throughout the legion's existence, creating military cultures that persisted for centuries.
All legions were given a number. The highest numbered legion that we know of was the 30th,
And each legion also had a moniker, which came from early battlefield accomplishments.
The 10th Legion was known as the Frotentis, which means of the strait, and is based on their early naval accomplishments.
The 12th Legion was known as the Fulminata, which means thunderbolt.
Most legions had a name based on a geographic area where they found early success, including Germany, Syria, Macedonia, Gaul, and Sicily.
And of course, each Legion had a standard, which was considered to be an almost sacred object.
A standard which was a golden eagle was carried into battle, and the most humiliating thing that could happen to a legion was the loss of its standard.
Emperors sometimes negotiated for decades to get lost standards returned.
The point of all of this is that the legions were large and important things that had a continuity that often lasted for centuries.
Legions didn't just disappear.
Which brings me to the subject of this episode, the legion no one of this episode.
Hispania, or the 9th Spanish Legion. Its origins trace back to the late Roman Republic,
most likely around the year 65 BC during the campaigns of Pompey the Great in Hispania,
which is the source of its honorary title, Hispania. By the time of Julius Caesar's Gallic
Wars, the Ninth Legion was a seasoned and respected force. It played a prominent role in Caesar's
conquest of Gaul and later supported him in the Civil War against Pompey, fighting at key
battles such as Farsalis and 48 BC.
Following Caesar's assassination, the Legion served under his heir, Augustus, during the
final conflicts of the Republic. After Augustus secured his power, the Legion was stationed
in Hispania for some time and subsequently deployed to the Rhine frontier.
Under Augustus and his successors, the Ninth Legion participated in numerous campaigns that
expanded and consolidated Roman power. For example, the Legion fought in the Pannonian
revolts in the Balkans. The Legion's most famous chapter,
began with the Roman invasion of Britain in the year 43 under the Emperor Claudius.
The Ninth Legion formed part of the invasion force that established Roman rule in southern Britain,
and it would remain associated with the British frontier for the next several decades.
This posting was both prestigious and dangerous,
as the Legion found itself at the forefront of Rome's expansion into one of Europe's most challenging regions.
During the early years of the conquest,
the Ninth Legion established itself in the modern city of Lincoln,
known to the Romans as Lindem-Kolle.
This location was strategically chosen to control the gap between the Pennine Mountains and the North Sea,
effectively dividing the unconquered tribes of the North from those already under Roman control.
The Legion's most severe test came during the Budica rebellion in the year 60 and 61,
one of the most serious challenges to Roman rule in Britain, which I covered in a previous episode.
When Queen Budica led her confederation of tribes and revolt, the Ninth Legion marched south from Lincoln to help suppress the uprising.
However, the Legion walked into a carefully prepared ambush and suffered catastrophic losses.
Classical sources suggest that the Legion lost most of its infantry, with only the cavalry
and senior officers managing to escape back to their fortified camp.
This disaster may have ended the story of most legions, but the Roman system was remarkably
resilient.
The Ninth Legion was rebuilt with fresh recruits and reinforcements, showing the Empire's ability
to recover from even severe setbacks.
Following its reconstruction, the Ninth Legion continued to serve on the British frontier,
participating in the campaigns of Nyas Julius Agricola in the 70s and 80s.
These campaigns push Roman control far into Scotland,
and the Legion likely fought at the famous Battle of Mons Grappius,
where Agricola claimed to have decisively defeated the Caledonian tribes.
Archaeological evidence suggests the Legion maintained bases in Northern England and Southern Scotland during this period.
The mystery of the Ninth Legion begins in the United States.
the early second century. The last definitive evidence for the Legion's presence in Britain
comes from inscriptions and archaeological finds dated to around the year 108. And this last
inscription can still be seen at the Yorkshire Museum in York, England. After this point,
the historical record becomes silent. No further inscriptions mention the Legion, no military
documents reference its activities, and archaeological evidence for its continued existence simply
vanishes. And I should reiterate that many of the legions from this period existed well into the
fourth or fifth centuries. If a lesion was disbanded, it probably would have been due to some
disastrous defeat, and there's no such defeat in the historical record. So what happened?
Well, we don't know. There is no definitive evidence pointing to anything. All we really have are theories.
The theory which dominated the 19th and early 20th century was developed by the German historian
and winner of the 1902 Nobel Prize in literature, Theodore Momson.
Momsen's magnum opus, and the work for which he was awarded the Nobel Prize, was titled
A History of Rome.
Momsen believed that the 9th Spanish Legion met its end in Britain, most likely during a major
but poorly documented military disaster in the early second century.
He placed this event sometime during or shortly after the reign of the Emperor Trajan
when evidence of the Legion just abruptly vanished.
Momsen hypothesized that the 9th was destroyed in the far north of Britain, possibly in modern-day Scotland,
during an expedition against the Caledonian tribes.
This theory was rooted in the assumption that the lack of later inscriptions in Britain
indicated its annihilation.
In his analysis, Momsen emphasized the pattern of Roman military,
administration and frontier policy. He believed that a major loss like the destruction of the
9th would explain the decision to withdraw from further northern expansion and ultimately to build
Hadrian's wall in the 120s under the Emperor Hadrian. Absent any other evidence, Momsen's hypothesis was
widely accepted for decades. And to be fair, it wasn't a crazy idea. It explained why the Romans
pulled out of Scotland, and it also ties cleanly to the last known location of the Legion.
Momsomson's theory was the basis for several fictional works,
including Rosemary Sutcliffe's 1945 novel,
The Eagle of the Ninth,
and the 2007 movie The Last Legion.
However, in the 1990s,
a significant archaeological discovery in Nymag and Netherlands
contributed to a major shift in scholarly thinking
about the fate of the Ninth Legion.
This discovery included a cache of Roman military artifacts,
notably tiles, inscriptions, and coins,
which provided fresh evidence
that at least elements of the Ninth Legion were present on continental Europe,
specifically in the Rhine Frontier Region, after its last known activity in Britain.
The Nymagod findings built upon earlier discoveries from the 60s and 70s,
including a tombstone of a centurion of the 9th.
But the 90s excavations reinforced the argument that the Legion,
or at least a significant detachment of it,
had been transferred from Britain to the Rhineland around the early 2nd century.
Among those more consequential finds were roof tiles stamped with the mark of the 9th Hispania,
and coins dating from the reign of Trajan and Hadrian,
strongly suggesting that these tiles and the structures they were part of
were constructed in the early to mid-second century.
This contradicted the long-standing theory popularized by Momsen and others that the Legion was destroyed in Britain.
Instead, the I make an evidence suggested that the Legion survived the Buda-Con revolt
and continue to operate after the year 108, the date of its last known inscription in York.
However, while this evidence indicates a presence of the 9th in Nymegan, it doesn't conclusively prove
that the Legion was stationed there, nor does it conclude what ultimately happened to it.
As a result, since the 1990s, the academic consensus has shifted away from a purely British-based
destruction of the 9th.
Instead, scholars now consider it more likely that the Legion was transferred out of Britain sometime
after the year 108, and ultimately vanished from history under uncertain circumstances
sometime in the second century.
The Nymagin artifacts changes the story of the Lost Legion, but it doesn't fundamentally solve
the mystery.
We still have no idea what happened in the Legion.
We can be reasonably sure that they weren't destroyed or disbanded in Britain, but that just
moves the mystery forward a few decades.
New theories have come forward, which include the Legion being sent to Judea, Armenia, or
the Balkans or just being merged into other legions.
Unless new archaeological discoveries are made, we may never know what happened to the Legio
Nonum Hispania.
So, no matter how many theories about them are put forward, absent new evidence, they might
forever be the Lost Legion.
