The Roman Auxiliary Cavalry of Britannia

The Roman Auxiliary Cavalry of Britannia
 
Who guarded the Wall? For much of its first 300 years of use Hadrian's Wall marked the north-west frontier of the Roman Empire. In movies such as The Eagle or Centurion we see the Roman foot soldier astride its battlements looking north, spear and shield in hand. But was its defence all about the humble infantryman? What of the cavalry? Why did many Wall forts include a mounted contingent within its garrison?
 
It has been calculated that sustaining a cavalryman with his kit and horse cost 5 times that of an infantryman. Why would the Romans invest so much in such an expensive asset?
 
We know from more recent times that cavalry can move at lightning speed, and are highly mobile, making them effective on patrols and as scouts, which would have been particularly important north of the Wall. They make speedy messengers, giving warning of sudden threats and incursions. In Roman times they would also have ensured food security, protecting local farmland and guarding supply trains to the Wall’s outlying forts.
 
But to my mind possibly the greatest significance of their presence is, they projected the image of power and renown of Rome and its imperial might. If you have ever seen the Household Cavalry in London or mounted police outside of a football (soccer) stadium you will get an idea of what a disciplined, armoured unit of Roman cavalry must have looked like to an Iron Age population.
 
Outlying forts, such as at Birrens and Netherby housed specialist, double-strength, mixed infantry and cavalry cohorts (milliaria equitata) as well as specialist scouts (exploratores) enabling them to command the local area and suppress any uprising of the local tribes. The effect on the indigenous people must have been as much psychological as physical.
 
But who were these cavalrymen? Well they certainly weren’t drawn from the Roman aristocracy as they often were in the time of the Republic. No, the names of their units give a clear indication the Romans recruited from all over the empire and mainly from the homelands of its conquered peoples. Germanic and celtic Gaulish units were prevalent, such as the Germanic units of the I Nervana Germanorum and the Cohors II Tungrorum. But regiments from as far away as Spain, modern day Bulgaria and Croatia have also been identified. However, as the needs of the empire changed over time individual units increasingly recruited from the local populations. With sons moving into the family business by joining the cohorts of their fathers and grandfathers.
 
So what was life like for the cavalryman? Well each troop, known as a turma, typically 30 men when at full complement, were housed in a single barrack block. Trios of men lived at the back of the building with their horses stabled at the front. There were surely few nights that troopers fell asleep without the sound of the snorts of their mounts and the sweet smell of hay and manure in their nostrils. Each room had a hearth set against the stable-side wall for warmth and cooking. The decurion, who commanded the turma, lived in rooms at the end of the block along with his family. Troopers ate, slept and kept their weapons and tack in these small rooms. It is also thought grooms and slaves may have slept in the roof space above.
 
The training for cavalrymen and their mounts was extensive and intense. If you have seen horses being drilled for modern day dressage you will get the idea, with each trained initially on a long rein to teach basic skills as well as special steps. It is likely horses were broken and prepared by specialists before being assigned to its rider. They learned to overcome their instinct to flee when startled and to cope in the noise and fervour of combat. The early instruction of the cavalryman would have focussed on mastering the basic skills of controlling and riding the horse whilst holding a sword or spear in the right hand and the shield and rein in the left. From there they would have progressed to learning to fight as a turma, with unit drills enabling large numbers of men to manoeuvre in battle.

The average cavalryman was well armed and armoured. He typically wore chainmail armour that allowed greater movement whilst on horseback. Their weapons consisted of the long cavalry sword often referred to as the spatha. They had a fighting lance and two shorter throwing javelins. Their shields were a variety of shapes including square and oval, but were usually flat with a steel rim and a rounded metal boss to enable it to be used as a weapon. It is not hard to imagine the damage the charge of even a small unit of auxiliary cavalry could inflict on the largely unprotected bodies of the tribal warriors of the north of Britain.

When researching for my Edge of Empire series, which focuses on the lives of the men of a mixed Germanic cohort, I was surprised by the amount of detail we now have on the everyday life of a Roman cavalryman. In their adventures I have worked hard to be faithful to that knowledge and attempted to bring it to life for the present day reader.

Best selling author, Alistair Tosh was born in Dumfriesshire, a place filled with ancient place names such as Torthorwald and Caerlaverock. But it was his visits, as a boy, to nearby Burnswark Iron Age hillfort and its Roman siegeworks that first fired his interest in Roman and Dark Ages history.
 
On leaving school he began a 35 year communications career, firstly with the Royal Navy, that included covert riverine and seaborne operations during the height of ‘The Troubles’ in Northern Ireland, before moving into the corporate telecommunications world. Military life is unique, and Alistair aims to reflect an authentic view of that experience and its language in his stories.
 
His debut historical novel, Siege, the first book in the Edge of Empire series, is set against the backdrop of the Antonine push into Caledonia. When not writing or researching, Alistair likes to spend time with family. He and his wife also love hill walking and have spent a great deal of time exploring the mountains of both the UK and Andalucia accompanied by their dog Hurley.
