Alternate history: what if Boudica had defeated the Romans?

“The three newly built Roman towns were all undefended,” says Miles Russell, historian, author and Senior Lecturer of archaeology at Bournemouth University. “Camulodunum, which housed ex-Roman soldiers and was the site of a temple dedicated to Emperor Claudius, was the main focus of Boudica’s anger.” Londinium, meanwhile, was a wealthy centre of trade and Verulamium had been built for the pro-Roman Catuvellauni tribe, described by Russell as “all traitors and quislings in the eyes of Boudica’s people”.

Now the warrior queen faced her greatest challenge. The Governor of Britain, Gaius Suetonius Paulinius, had raced back from putting down a druid rebellion in Wales at the head of 10,000 battle-hardened soldiers. They may have been far more disciplined and better armed than Boudica’s ragtag army, but they were heavily outnumbered – as much as four to one, according to Russell. When the two sides met at a place called Watling Street, Boudica had to avoid playing into Suetonius’s hands.“Suetonius was, as far as Rome was concerned, the right man in the right place; an experienced soldier and a no-nonsense individual who did not shrink from making tough decisions,” says Russell.

Not all Britons were on Boudica’s side – far from it. Many had thrown their lot in with the Roman government, seeing no benefit in siding with the anarchy and lawlessness of the rebels

Watling Street was where Boudica’s army was broken, but could it have played out differently? Boudica would have had to ensure that Suetonius did not choose the battleground, where the Romans could position themselves at a bottleneck so that her larger numbers counted for nothing. Then it could too easily have turned into a massacre of the disorganised and unarmoured Britons.

Breaking the bottleneck

We might imagine Boudica’s warriors rushing across a wide field before the Roman javelins, or pila, caused too much damage and swarmed the shield wall, breaking it apart by the ferocity of the charge. With Suetonius in retreat and his remaining soldiers scattering, Boudica would have claimed a remarkable victory over the Romans.

That would not mean she had rid herself of all her enemies, though. The people of Britain were in no way united, with deep-seated tensions permeating between the tribes. “Not all Britons were on Boudica’s side – far from it. Many had thrown their lot in with the Roman government, seeing no benefit in siding with the anarchy and lawlessness of the rebels,” Russell asserts.

Boudica would have had to contend with them, and also keep her own Iceni and ally tribes under some control, as many warriors simply wanted to loot and kill. “It is likely that the victorious Britons would have vented their anger upon the tribes allied to Rome, such as the Atrebates and Regni, before eventually turning on each other,” says Russell. “Boudica would have found it difficult to call a halt to the slaughter.”

There would not have been a Roman force left that was strong enough to retaliate, either, other than handfuls of soldiers in the west and north. “The Romans would have almost certainly been kicked out of Britain,” is Russell’s conclusion. “Emperor Nero could have done little more than order a full withdrawal of all forces from Britain, allowing him to regroup and consider whether to re-invade or plan punitive reprisals.”

The chances of a second invasion would have been small given the high cost, so the prestige of Rome would have been seriously tarnished. Russell goes even further when it comes to Nero’s reputation, which was already shaky due to his scandalous behaviour and lifestyle, and says the damage “would have been irreparable”. Nero’s reign may have been cut even shorter by intensified charges of corruption, extravagance and tyranny.

Britain makes an exit

Rome’s troubles with Britain, which had been within the trade orbit of the Roman empire for around a century, would not be over even after they left, Russell claims. “It’s likely that, as in Germany after Rome’s army left in AD 9 following a massacre, the peoples of Britain would have become a constant problem at the edge of the empire, sending raiding parties, occasionally trading and sometimes even asking for help to resolve internal disputes.

“Rome may have sent troops across the Channel from time to time to quell the irritant, but it’s unlikely they would have launched another full-scale invasion,” Russell adds. “Eventually, British tribes may well have migrated into the collapsing Roman Empire, just as the various Germanic tribes did throughout the fifth century.”

As for Boudica, how would her legacy have survived over the centuries? The only sources relating to the uprising are written by two Roman historians – Tacitus and Cassius Dio – so it’s not unreasonable to assume she may have been left out of the histories altogether out of shame that a barbarian – a woman at that – had defeated the might of Rome. Russell, however, feels differently – after all, Tacitus and Dio had made Suetonius the hero of their narratives as a direct contrast to the ineffective Nero.

“Had Boudica won, her story would may have become more famous,” says Russell, “as the woman who successfully defied Rome and helped end the tyrant Nero’s reign. Her tale would have taken on a more moralistic slant in the Roman histories.”
