I’ll start this off:
For four years, from 6 AD to 9 AD, the Romans were busy fighting a giant war in Illyria: The Bellum Batonianum. It is also known as the Great Illyrian Revolt, which is what I prefer to call it, since it rolls off the tongue a bit easier.
So, the Great Illyrian Revolt. It was basically what it says on the tin: The Romans were facing a massive uprising by a coalition of Illyrian tribes. Suetonius calls it the most serious foreign war since the Punic Wars. It was fought across the entire western Balkans, and at times involved upwards of 100,000 Roman and auxiliary troops at a time. Augustus ordered Tiberius to break off ongoing operations in Germany and move his army to the Balkans. The war stretched Roman resources: We’re told that at one point, the Romans resorted to purchasing and freeing thousands of slaves to fill out the armies. At stake was Roman control of the key region of Illyria, and a potential collapse of the Roman eastern flank. We’re told of panic in Rome, and of fears that an invasion of Italy itself might follow. According to Velleius Paterculus:
So, it was a pretty major deal. And yet, no one ever talks about it. If you’ve never heard of this war, I don’t blame you: It’s hardly ever mentioned even in biographies of Augustus or Tiberius. The most you’ll hear of it is usually along the lines of: “Oh, yeah, at this time there was some fighting going on in Illyria.”
Why doesn’t anyone think it’s important? Well, for one thing, the Romans won. Like with so many uprisings against Rome, the end result was just an even tighter imperial grip on the rebelling region. So, any fears of barbarians swarming into Italy were unfounded this time around. There are also no famous battles or other episodes from the war that make for particularly good stories. So, maybe it makes sense that it’s never mentioned much except in passing.
So, why do I care? Because I think that this war puts a much more famous episode in a different light. In 9 AD, immediately following the conclusive Roman victory in Illyria, three Roman legions were ambushed and wiped out in Germany. I am of course talking about the Battle of the Teutoburg Forest.
Everyone knows about Teutoburg. It’s probably the most famous Roman defeat ever, or at least the second most famous, after Cannae. Search YouTube, and you’ll find a ton of documentaries about it. Teutoburg is often presented as the battle that, in a single blow, changed history, and ended Roman eastward expansion. Instead of conquering the Germans, as they had planned, the Romans stopped at the Rhine. We’re told that the destruction of the legions in the forests of Germany shattered the Romans’ view of themselves as invincible. Augustus himself is said to have freaked out, and, according to Suetonius, he took to banging his head against the walls of his palace, shouting: “Varus, give me back my legions!”
And so forth. Now, my problem with this is that the Roman reaction to Teutoburg, and the way the battle is often presented as a turning point in history, never really made all that much sense to me. Sure, it was a defeat, and losing three legions is pretty bad. But, still: It was *one *defeat. The Romans had lost battles and even whole armies before. The Teutoburg disaster, by itself, just doesn’t seem like enough to wreck the Roman psyche, and turn their policy regarding expansion upside down, the way we’re often told that it did. It feels like we’re missing something.
Of course, one thing that is often missed, or rather not mentioned, is the simple fact that conquering beyond the Rhine might not be all that great an idea to begin with, unless you want to slog your way through dank forests filled with crazy Germans all the way to the what is now Russia. If you’re going to stop somewhere, the Rhine is a pretty logical place to do it. But I think that a more immediate thing that everyone is missing might be the Great Illyrian Revolt. Teutoburg is usually presented as happening in a vacuum. As I said, though, losing three legions in Germany, while bad, shouldn’t really be enough to spook you as badly as we’re often told that it spooked the Romans. However, losing three legions in Germany, immediately on the heels of spending four years and a ton of resources putting down a very scary rebellion in Illyria? Yeah, that might be just about enough to make you reassess your foreign policy, and turn your attention towards consolidating your frontiers. The situation on the borders, taken as a whole, probably didn’t’ look super healthy at that point.
Suetonius does connect the two in his biography of Tiberius:
It’s just a thought. Anyway, that’s my entry for wars we should probably know about. Have you got any?
