THE AGE OF ARTHUR: PART 8

This is the Eighth-part of our discussion of Britain in the so-called Age of Arthur: the 5th though the mid-6th Century A.D. It is a fascinating period, with the Classical civilization of Greece and Rome giving way to the Germanic “Dark Ages”. It was the sunset of Celtic-Roman culture in Britain; it was the Age of Arthur!

But who was Arthur?

Before we answer that question, it is necessary we understand the world in which he lived.

(Read Part Seven here)

BRITAIN STANDS ALONE

The last quarter of the 5th century was a grim time for those who looked to Rome and the model of classical civilization it represented.

In 476, Romulus Augustulus, the teenage Western Roman Emperor, was forced to abdicate his throne by Odoacer; leader of barbarian  feoderati mercenaries in Italy. The Western Emperor had long been a figurehead, with true power residing with the Magister Militum (“Master of Soldiers”); a position held in the 5th century by one Romanized-Barbarian officer after another.

Romulus had himself been placed on the throne by his father, Orestes, one of these Romanized German commanders. Odoacer killed Orestes, and seized the Emperor in Ravenna.

The boy-Emperor’s life was mercifully spared; Odoacer granted him an estate in Campania and a life-time pension. But Romulus was the last to hold the title of “Western Roman Emperor”. Odoacer went on to rule Italy thereafter as “King”; and as an autonomous vassal of the Eastern Empire.

Few in the West likely noticed, much less cared. By this time, the provinces that once comprised the western half of the Roman Empire had for some time been under the control of various “barbarian” powers. Gaul was divided between Franks in the north, the Burgundians in the east, and the Visigoths in the south; with an ever-shrinking Roman successor state (ruled by Syagrius, a noble Romano-Gaul who still bore the title of Magister Militum per Gallias) in the north-central portion of the province; and the British territory of Armorica/Brittany. Spain was divided between this same Visigoth kingdom (centered still in Aquitaine), and the German Suevi. North Africa, once the breadbasket of the Western Empire, was now a militant and piratical Vandal kingdom; centered on the former provincial capital of Carthage.

Of the former provinces, only Britain fought on, resisting Germanic occupation.

There are cogent reasons why of all the Western Imperial provinces Britain alone maintained its independence and identity.

The first is geography: as an island, Britain was not susceptible to the wholesale invasion and migration of Germanic nations seen in the rest of the Western Empire. Only the Picts in the north were in a position to overrun the island and submerge Roman civilization. That this did not occur is testament to the second factor: leadership.

From the first decade of the 5th century, when Rome abandoned the Britons to their own devices, strong leaders had emerged to maintain a loose unity among the Celtic Romano-Britons; and to beat back raider and invader. First may have been  Coel Hen (“Old King Cole”), perhaps the last official Dux Britanniarum (1) (commander of the Roman forces stationed in the north of Britain); and then Vortigern, prince of Powys and “High King” of Britain, managed to rally the island’s forces and coordinate a common defense for most of the first half of the 5th century. Vortigern’s long hold on power saw the British position in the east of the island erode, however, as the barbaric “Saxons” settled first as mercenary feoderatii and later as enemy invaders (though the settlement of Anglo-Saxon feoderatii along the eastern coasts of Britain may date back to the late Roman occupation). But Vortigern was followed by Ambrosius Aurelianus, who may have bore the title of “Riothamus”, or “Supreme King” among the Celtic petty-kings of Britain. Ambrosius struggled with mixed success to contain the Saxons in the eastern portion of the island.

THE CAVALRY ADVANTAGE

A third and perhaps the most critical factor in the success of Britain’s defense against the tide of Germanic barbarism was cavalry.

Most Germanic tribes had their own cavalry traditions. While the majority of  warriors tended to fight on foot, Germanic nobles and their retainers tended to serve as horsemen. Some nations, such as the Ostrogoths and Vandals, became primarily cavalry warriors as soon as circumstances and a ready supply of horses allowed.

Not so the Anglo-Saxons.

These northern German/Scandinavian people were seafarers, pirates, who preferred to fight on foot. In battle they formed up in a tight, compact mass of infantry; as either a “shieldwall” or, when on the attack, the “swine array” or “boar’s head” (wedge) formation. Even though nobles might ride horses to battle, they dismounted to fight. Against cavalry, the Saxons were at a disadvantage. With no traditions of cavalry warfare of their own, they had no tactics to deal with horsemen when confronting them.

It has been suggested by many historians that the Saxons were fearful of cavalry. While this may have been true to some extent (especially after stinging defeats at the hands of the British warlords), it is not likely from a cultural standpoint. Scandinavian chieftains and their household warriors rode horses to battle, as stated. But the horses of Scandinavia and the north German plains are small, sturdy animals; unsuitable for cavalry warfare. It was primarily for this reason rather than some kind of unreasoning terror of horsemen that the Saxons had no cavalry tradition of their own; and were vulnerable to cavalry.

Conversely, since the 3rd century, the importance of cavalry within the Roman army had steadily increased. The emperor Gallienus, in the 260s, created a  mobile  cavalry corps stationed at Milan, in northern Italy; as a rapid-reaction force capable of responding to barbarian invasions anywhere along the broad frontiers of the Rhine or Danube. This was the archetype for the future “mobile field armies” (the comitatensis) of the later Empire. During the Roman occupation, the Count of Britain (Comes Britanniae) commanded such a mobile field army, which included 1,800 cavalry (2).

While this force was withdrawn to support the imperial pretensions of Constantine III in 407, other cavalry resources were left at the disposal of Britain’s leaders for the island’s defense; and Britain may have owed its salvation to them.

In the 1st century AD, the nomadic Sarmatian people established dominance in the Ukrainian steppe. By the 2nd century, these excellent horsemen had migrated into the mid-Danube region, coming into conflict with the Roman Empire. After defeating them in war, the Emperor Hadrian settled 5,000  Sarmatian horsemen in Britain; as a reserve, backing-up the garrisons along Hadrian’s Wall. It is not known if they brought their families with them (a likely circumstance); or married local women. In either case, they continued to exist as part of the British population for the next two centuries. Sarmatian units are named as part of the Wall garrison till the very end of the Roman period in Britain.

There were also other heavy cavalry units stationed on the Wall and left there after the Roman departure. Many of these were “heavy” cavalry, and at least on was a unit of catafractarii (very heavily armored lancers).

Further, the northern British kingdoms of Strathclyde in the west and Gododdin in the east both maintained a  tradition of cavalry warfare and a semi-nomadic lifestyle that speaks directly to their intermingling with and influence by these Sarmatian settlers.

The Roman authorities had established these friendly client peoples  as a buffer(primarily the Votadini tribe, who later formed the Kingdom of Gododdin; and the Damnonii and Selgovae who together comprised the later Kingdom of Strathclyde).  One factor preventing the Picts from overrunning the whole of Britain during the turbulent days following the Roman withdrawal; or later, when the Saxons were ravaging the southern portion of the island during the 450s, was that between their highland kingdom, Alba, and Roman Britain stood these formidable pseudo-Sarmatian mounted warriors of Strathclyde and Gododdin.

Sometime in the late 4th century or the first half of the 5th century, a large band of warriors from the Gododdin Votadini tribe, and their families, were settled in northern Wales. Led by the famous Cunedda, these founded the Kingdom of Gwynedd. It is likely that at least the nobles of Gwynedd maintained the cavalry traditions of their homeland in the north; providing the British leaders with still another source for cavalry.

The northern British horsemen were not the only source of good quality cavalry available to the defenders of Britain. Across the Channel from Britain, in Armorica, the Alans had been settled by Flavius Aetius, Magister Militum of the West during the reign of Valentinian III. Like the Sarmatians, these were a nomadic people of the Eurasian steppe. Though originally a branch of the Central Asian Massagetae, they are often described as a Sarmatian people; and the distinctions between them might well have been slight. As discussed previously, it is likely the Alans merged with the British settlers who migrated to Armorica in mass in the mid-5th century.

Armorica was very likely under the authority of the British “Supreme King”; who in the later half of the 5th century was Ambrosius Aurelianus. Geoffrey of Monmouth links Armorica with Ambrosius, as the place of his exile when hiding from Vortigern in the 440s. As discussed earlier, Alan horsemen may well have served in his Comitatus/Bucellarii (bodyguard regiment); and the Armorican Alani would have been available to the British military leadership (See Ch 6).

MASTER OF HORSE: THE EMERGENCE OF ARTHUR

Ambrosius Aurelianus took over the leadership of the Britons in the late 450s. For the next several decades, he carried on a long struggle against Saxon, Pict and Scotti (Irish). While the bulk of British military garrisons and levied contingents would have been infantry; the military elite were cavalry. Only horsemen had the strategic mobility to rapidly respond to the midnight beacon on the hilltop, signaling “raiders from the sea”, or a Saxon incursion across the “debatable lands”!

Did Ambrosius personally respond to every alarm? As Riothamus of Britain, only he had the authority to command the contingents of the various petty-kings of Celtic Britain. But the duties of “Supreme King” included more than leading armies; and not every incursion required the full response of Britain’s military resources.

Using the model left them by the Romans, the Britons would have layered their defenses. Fortress garrisons along the Saxon or Pictish frontier would deal with small-scale raids; and give advance warning of larger threats as they materialized. Local “petty kings” would then respond to such threats to their territory; leading their household warriors, augmented when necessary by town militias and tribal levies.

When a threat too dangerous for the local ruler to safely deal with materialized; but not so large as to require a general mobilization of British forces, then Ambrosius’ mobile cavalry force could be dispatched. Galloping up one of the numerous Roman roads or connecting byways to the endangered area, Ambrosius’ horsemen could be at any threatened part of the island in a week’s time.  Like Gallienus’ 3rd century mobile cavalry force, the arrival of a strong cavalry reinforcement under able leadership could shift the balance in the Britons favor.

But galloping across the British landscape was young man’s work, the work of a young but capable subordinate.

Ambrosius Aurelianus’ birth date is unknown. If, as previously theorized, he was a youth fleeing Vortigern’s persecution in the 430s; he must have been in his middle years when he came to power in the late 450s. After his defeat in Gaul, “Riothamus” was wounded; and though he survived, such battle wounds took long to heal and were often permanently debilitating. While it is certainly possible for a vigorous older man to lead his warriors on hard campaigns; it is unlikely that Ambrosius was in any condition to gallop off at the head of his  cavalry in response to every midnight alarm!

So who took over this role? Here, again, the late Roman practice shines light on the question.

In the late Roman Army, the supreme commander of Roman forces bore the title of Magister Militum (“Master of Soldiers”). He was assisted by a second-in-command, titled Magister Equitum: “Master of Horse”.

Ambrosius, “Last of the Romans”, must surely have been assisted by a trusted lieutenant; his “Master of Horse”. To this individual would be entrusted the command of the mobile cavalry force that kept the barbarians at bay.

Could this man, Ambrosius’ strong right-hand, have been Arthur?

What we know of Arthur is that he led the Britons in the generation after Ambrosius. Ambrosius was alive until sometime around 500AD; though by this date certainly an aged, revered ruler. He must have groomed someone to take his place much earlier, perhaps as his Master of Horse.

Geoffrey of Monmouth’s “History of the Kings of Britain” has Arthur as Ambrosius’ nephew. Such a familial connection would certainly make a great deal of sense. Perhaps Ambrosius’ young nephew began his career within Ambrosius’ comitatus. Revealingly, the later British term for such bodyguard units of great leaders was Teulu: “Family”.

(2) Jones, AHM. The Late Roman Empire. Johns Hopkins University Press (1986).  The force under the command of the Comes Britanniae was composed of 6 units of cavalry, 2 legio comitatensis, and 1 regiment of auxilia. This mobile reserve numbered (on paper) 4,800 men: 300 troopers per cavalry vexillatio (1,800 total); 1,200 soldiers per legio (2,400 total); and 600 soldiers for the auxilia regiment.
