AD 490
At the beginning of the Ostrogothic invasion, some believed that the Roman army would confront the aggressors out in the open and force a decisive result on the battlefield. If Odoacer had his way, that is exactly what the Western Empire would have done. His strategy would have entailed maneuvering the majority of their armed forces in to direct confrontation with Theodoric’s army, possibly on the banks of the river Sontius. It was risky, but necessarily a foolish move. Much like the Empire itself, the army experienced a period of rejuvenation in the absence of civil wars and foreign invasions. Augmented by mercenaries from various Germanic tribes, at the military’s core stood thousands of professional soldiers, ranging across various different unit types (comitatenses, limitanei, auxilia palatine, pseudocomitatenses, etc). Though its fighting strength had been severely reduced due to the loss of most Roman territories in the West, this was actually a blessing since Rome’s forces were no longer dangerously overstretched. Now they could concentrate their full defense on Italy. If the Romans accepted battle with the Ostrogoths, there was a possibility that they could end the war just as it began.
But there was also the chance that Theodoric would crush the Empire’s forces and secure victory in one fell swoop. Orestes may have been a less experienced general compared to Odoacer, but even he knew that the Empire could not risk everything by giving Theodoric exactly what he wanted: an open battle where he could destroy his enemies all at once. In any case, recent history showed that battles had become rare events in Rome’s wars against foreign adversaries, unlike the many civil wars that were decided by such an encounter. Whilst the larger armies still operated efficiently in massed encounters, the smaller units within them were also especially suited to small-scale mobile warfare. That was a particular strength that Orestes wanted to utilize. As a consequence, this war could potentially become a long-drawn-out conflict that would gradually drain the Empire’s resources and morale. But it was better than the alternative.
Ever since Theodoric’s army entered Italy, much of the fighting was relegated to many skirmishes and generally small-scale combat. The Ostrogoths captured and ransacked numerous small settlements, but thus far they remained unable to lure the Romans into a battle in which they could secure a decisive victory. Twice they had besieged Mediolanum in AD 490. The first attack ended when the Ostrogoths withdrew from the siege shortly before the arrival of an army of reinforcements under the command of Orestes’s brother Paulus. On the second occasion, the Ostrogoths returned in greater number and surrounded the city once more. Additional soldiers would not be ready for deployment for months, and so Odoacer chose to lead the city’s garrison in a counterattack against the Ostrogoths. Both sides suffered medium casualties, but neither side was able to deliver the crippling blow. The invaders retreated and Mediolanum was again spared.
The combination of Orestes’s cautiousness and Odoacer’s boldness had served the Roman war effort well. But it seemed inevitable that the conflict would take its toll on the population of Italy. Orestes just did not expect it to be so soon. Many people were still uncertain if the West could triumph and others wanted the war to be over as soon as possible. It seemed like sooner or later, Orestes would have no choice but to agree to meet Theodoric in open battle where the fate of the Empire would most likely be decided.
As for his son, the emperor Romulus Augustus remained secure at Ravenna. In all the time that he has been kept in the background as a figurehead, Orestes saw to it that Romulus received the best of Roman education, as well as many lessons in the art of war. But war simulations were very different from the real thing and Orestes was unsure of what kind of military leader Romulus would be. After so many setbacks that had brought the Roman world to its knees, it seemed too much to hope that Romulus could be of the same caliber as Julius Caesar, Trajan or Constantine the Great. Whatever kind of war-time emperor he turned out to be, Orestes just hoped that Romulus wouldn’t share in the fate of either Valens of Valerian. An emperor’s death on the battlefield could be disastrous, but to be captured and imprisoned at the hands of the enemy was a humiliation that would almost certainly finish the Empire at this point. Yet Orestes was also aware of the fact that he might not survive this war. If that happened, then Romulus Augustus would have no choice but to actually be an emperor, or else Odoacer would most likely take control by becoming the new power behind the throne as magister militum.
Such thoughts of the future had to be set aside for the time being. Right now Orestes needed his alliance with Odoacer in order to save the Western Empire. Despite some reluctance on Orestes’s part, the duumvirate had decided to seize the initiative by finally going on the offensive. Theodoric had encamped the Ostrogoths at his temporary headquarters in Ticinum, and it was there that the duumvirate intended to bring the war to its conclusion.
