AD 493
The fall of Mediolanum, the loss of the army garrisoned behind the its walls, and the death of Odoacer all would have amounted to a decisive defeat for the Western Roman Empire, had the duumvirate committed the total strength of its military force in the north to a single location. After the Visigoths entered the fray, the duumvirs divided the northern army between themselves. Odoacer was to hold Mediolanum while Orestes stationed his troops in Verona. From there, he would augment his units with additional soldiers from the reserve army that was stationed in Italia Suburbicaria. With this increase in manpower, Orestes was confident that even the Ostrogoths and Visigoths would be overwhelmed by the two armies of the duumvirate.
Odoacer’s demise brought this plan to an abrupt end. For years the two members of the duumvirate despised one another. Outwardly, their alliance was crucial in fostering civil accord to a certain degree between the Roman and Germanic peoples of Italy. They also constantly plotted against each other, however. The politics of the western court were dominated by plots and intrigue, and the duumvirate was no exception. Ironically Odoacer’s death now left Orestes as the single most powerful man in the Western Empire, but the timing couldn’t have been worse.
Shortly after Orestes’s army regrouped at Placentia, the surviving duumvir had to reconsider his strategy for what could possibly be the defining moment in his life. The most obvious option would be to return to Ravenna. Unlike Mediolanum, the western capital had the advantage of being connected to the Adriatic Sea through two harbors. The surrounding marshlands that surrounded Ravenna acted as a natural defense grid, meaning that siege warfare would be more difficult to endure for the besiegers rather than the besieged. At best, the Ostrogoths could only blockade all land routes that led into the capital. As long as Ravenna retained its access to the sea, it could be continuously resupplied. Such an advantage meant that Ravenna could endure months, even a few years, of being surrounded by the enemy.
But Mediolanum showed that no city, no matter how well defended, could hold out indefinitely. Not even Ravenna could be saved if the Ostrogoths found a way to obstruct its access to the sea. Orestes took into account the resourcefulness of his opponent. He doubted that Theodoric would reach out to the Vandal navy for assistance. The Ostrogothic king wanted all of the Western Empire’s remaining territory for himself, which included Sicily, the island that the Vandals wished to reclaim for their kingdom. Despite this, it was conceivable that he would resort to building his own warships, the cost of which would be the time it took to arm and train a fleet. Once Ravenna was cut off from the outside world, Theodoric’s numerically superior army of Ostrogoths and Visigoths would almost certainly succeed in conquering the capital.
Faced with such terrible odds, Orestes made the ultimate decision to remain at Placentia where he would make his last stand. He also chose to divert a large portion of his army back to Ravenna in order to enhance its current garrison. It was a sacrifice that further diminished his hope for victory, but it was also a necessary one. Even at full strength, his army was still outnumbered by the enemy. By increasing the number of Ravenna’s defenders, the capital would have a better chance at repelling direct assaults on its walls. In choosing to remain at Placentia, he was buying more time for the Empire to make any last-minute preparations for the defense of their last stronghold in the north. In the event of Orestes’s death, command of the Empire’s last defense would fall to the emperor Romulus Augustus. Though it had taken longer than expected, Orestes always intended for his son to eventually rule on his own, absent the interference of the duumvirate. By now, it was an outcome that the Magister Militum welcomed. Romulus was in his early thirties and the strain of old age was beginning to affect Orestes.
There was one more option that Orestes had to consider. Ever since the beginning of the conflict, he had dispatched messengers to the neighboring kingdoms of the Western Empire with a general call for assistance against the Ostrogoths. The Romans’ margin of success without foreign military aid was thin in AD 489, and had just become even thinner after the defeat at Mediolanum. In terms of those closest to the Italian border, the most obvious options were the tribes who carved their own independent kingdoms out of Gaul: the Burgundians, the Alemanni, and the Franks; Orestes even reached out to the Visigoths before their eventual response in the form of an army that saved Theodoric from certain defeat. The rest couldn’t be bothered to help the West. Most of these kingdoms were still consumed either with consolidation of their current holdings, or even further territorial expansion. Regardless, Orestes had to try one more time because it seemed as though the West was on the verge of giving up.
With more troops being siphoned out of the reserve army for the defense of Ravenna, much of Italy was starting to believe that Theodoric had already won. If the center of the western government fell to conquest, the rest of the peninsula would not be able to offer an effective resistance against the Ostrogoths. Some towns and cities chose to remain loyal but the majority had virtually taken a stance of neutrality at this point. Without going so far as to openly switch sides, it seemed as though all of Italy was on stand-by, cautiously waiting for the final outcome of the war. Even the Senate of Rome was starting to consider the possibility of abandoning the Empire as a lost cause.
However, there was still one institution that Orestes had yet to approach. Throughout the course of the fighting, the Holy Catholic Church - the western half of the overall State Church of the Roman Empire - labored to help the people of Italy during this period of war. As a testament to its increasing power and prestige, one of the few things that Orestes and Odoacer agreed on was to stay out of the Church’s affairs. The scope of its influence, which had never been confined to the borders of the Roman Empire at its height, now far exceeded the reduced boundaries of Italy and Dalmatia. Granted, Catholicism and Arianism were locked in a bitter struggle for the conversion of the barbarians. Even still, a growing number within the population of Western Europe remained loyal to the Trinitarian doctrine as espoused in the Nicene Creed. Combined with the subject of Papal Primacy, the Roman Pope had in many ways become more important than either the western emperor and his magister militum in the eyes of catholic Romans and non-Romans alike. Far from viewing this as a threat to what remained of Imperial power, the Church was Orestes’s last hope to secure an alliance that could save the Western Empire from destruction. He only hoped that at least one of the barbarian monarchs had enough foresight to see the advantages of entering into a communion with the See of Rome.
Orestes was confident that the Pope would consider intervening on behalf of the Imperial government, given how much incentive there was to maintain the status quo between the western court and the Holy Church. The Papacy had every reason to start reaching out to the Germanic kings in Gaul. For instance, Romulus Augustus adhered to Catholicism, a stark contrast to the Arian beliefs of Theodoric. Even if the Ostrogoth had enough political acumen to avoid a direct confrontation with the Church, the Pope was hardly inclined to trade a traditional Roman emperor for a heretic king; a king who also happened to be an oath breaker, as he demonstrated when he betrayed his word to the Archbishop of Mediolanum by putting Odoacer to death.
An alliance with Rome was not without certain benefits for the barbarians either. The obvious political advantages notwithstanding, a Germanic sovereign who came to the rescue of the Western Empire on behalf of the Pope would go a long way in securing the allegiance of the catholic Christians in his territory, including the Roman aristocratic families that remained behind after Imperial authority vanished in Gaul. Nevertheless, the fact remained that it was desperate attempt on the West’s part as there was still a good chance that even the Pope’s call for assistance could be denied. But there was no other option left. Either the Church’s influence would succeed where the Empire’s failed, or Theodoric would dissolve the last remnant of the once whole Western Roman Empire.
