One of Rome’s most famous defeats was in the forest across the Rhine where three whole legions were wiped out. Rome certainly had defeats up to this point, but this one was particularly bad to the point that over the next five years Rome pulled troops from all over the empire to deal with this defeat. So while this event had a major psychological affect on Rome, the defeat itself isn’t the really interesting story. Rather it’s how the whole thing was set up, and the seeds for this defeat appear to rest with one German’s desire for revenge/power and the elaborate scheme he undertook. The story is one of blind ignorance on the part of the Romans, actions of the past coming back to hurt, and paying attention to the tactics and strategy of your enemy if you want to win.
The story of Teutoburg Forest is one of deception and well-planned ambush such that the Romans had no choice but to lose. It begins with a German, Arminius, a member of the Cheruscan tribe, who long ago was held hostage in Rome before Rome began to draft non-Romans into their auxiliary corps. He was taken as a child when his father lost against the Romans and taken to Rome as a hostage to ensure the Cheruscans would behave. What exactly happened to Arminius at Roman hands is unknown, and further, it is not clear what his motivations were (revenge, return to chief position in Germany) after that captivity. But, Arminius clearly paid attention to how Rome won it’s battles and used this to achieve his goals. Rome could not be defeated if out in the open, but if you could spread them out, or get them in close quarters with little room to maneuver, then you had a chance of beating them. So Arminius went into the Roman Auxilia as a cavalry officer (he was a German noble – easy for him to show his superior training for auxilia leadership) and acted as the loyal German and local guide to all things German. It appears that he was interested in gaining prominence and clout with the German tribes back home, so maybe he needed to show a spectacular victory to gain complete power and regain the position that was robbed from him when he was taken hostage, but again, exact motivations are not clear. What he did well though was make sure he was in the right place at the right time to influence decisions.
In the past, Rome had always had problems with the Germans – indeed, long before the days of Caesar the Germans had managed to invade far enough south to wreck havoc on Rome itself, and Rome had long memories. So in AD 6-7, Augustus wanted to further pacify the German Tribes and finally put some prolonged power across the Rhine. So he took a Roman General who in the Eastern Empire had done a masterful job politically and sent him into Germany across the Rhine to further placate the tribes, show Rome’s might, and politically play the tribes off one another. Or that was what was believed to have been the original motivation. For all we know this was a reconnaissance in force. Regardless, the Roman General, Varus, led three Roman Legions into Germany across the Rhine, and who do you suppose his local auxilia guide was? That’s right, Arminius. Arminius was there to go with the Romans into his former homeland and convince the Romans he was their erstwhile ally and friend, and they should follow his advice rather than that of the senior military staff. Here’s where the blind ignorance comes in – no one apparently suspected Arminius of anything sinister here – either because he did such a good job acting as the loyal Roman subject, or because he charmed Varus into believing him over his own staff. But once that trust was in place, Arminius used it well and led the Romans to exactly where he needed them to go – a spot where their ability to maneuver would be limited and the Germans could begin to wear them down and begin to set up a masterful ambush.
Now that Arminius had the Romans where he wanted them, he left his final deceit in place by telling Varus the way to proceed was to march through “a shortcut” which would get the Romans to their destination faster, and then leaving in that direction to act as a scout. Varus, still believing Arminius to be the faithful subject of Rome, marched in this direction while his legions began to be nibbled at the edges by German attacks and rather than listening to his senior officers, continued to march deeper into the forest. As the legions began to realize they terrain they were marching into was a place where they could not maneuver, the Germans began to raid the Roman column winding through the forest, easily inflicting casualties on the Romans while melting back into the woods with little damage. With these raids and Arminius not reappearing, it finally sunk in that the Romans were trapped and that their “ally” had set up the whole thing. An attempt to break out was made, with the remainder of the Roman cavalry being trapped and wiped out by the surrounding German groups now in their native terrain. Varus now despaired and did the “Roman” thing of committing suicide, and it was left to senior officers to try and lead what was left of the march-tired and increasingly wounded Roman Legions out of the woods. Things went from bad to worse in that they found the only way out was through the exact terrain where Roman tactics were doomed to fail – up through a funneling hill with the Germans on the other side of the barricades at the top of the slope. The Romans made an attempt and failed. Arminius and the Cheruscans, along with other allied German tribes wiped out three legions – and only a few fleeing legionaries managed to make it back to Roman lines to tell of the carnage.
Deceit for setting up an ambush in terrain where the enemy’s tactics cannot succeed. Arminius learned well and got his revenge for his captivity and gained the chiefdom of the Cheruscans, all because his Roman”allies” never thought to question the person leading them into enemy territory. Sometimes actions can have consequences years after they occur, and in my opinion, this was one of them.
