We have seen that there had been friction between the Emperor and his Viceroy in Italy, and that Odovacar had thoroughly defeated the Rugians whom Zeno had stirred up against him. The thought now occurred to Zeno or his advisers that he might at once punish Odovacar and deliver the Illyrian provinces from the menacing presence of the Ostrogoths by giving Theoderic a commission to supersede the ruler of Italy. Theoderic accepted the charge. A compact was made that (in the words of the chronicler) “in case Odovacar were conquered, Theoderic should, as a reward of his labours, rule in place of Odovacar, until Zeno came himself.”113 The last condition is simply a way of saying that Zeno reserved all the Imperial rights of sovranty.
At the head of his people, numbering perhaps about 100,000,114 Theoderic set forth from Moesia in the autumn of A.D. 488. Following the direct road to Italy, past Viminacium and Singidunum, he approached Sirmium, and here he was confronted by a formidable obstacle. This town was in the possession of the Gepids, who now blocked Theoderic’s path. The place was taken after fierce fighting, but the Goths passed on with their booty and the Gepids reoccupied it. The winter, spring, and summer of the following year were spent somewhere between Sirmium and the Italian borders, and the causes of this delay are unknown.
It was not till the end of August (A.D. 489) that, having crossed the Julian Alps, the Ostrogoths reached the river Sontius (Isonzo) and the struggle for Italy began. Of this memorable war we have only the most meagre outline. The result was decided within twelve months, but three and a half years were to elapse before the last resistance of Odovacar was broken down and Theoderic was completely master of Italy.115
It was perhaps where the Sontius and the Frigidus meet that Theoderic found Odovacar in a carefully fortified camp, prepared to oppose his entry into Venetia. He had considerable forces, for besides his own army he had succeeded in enlisting foreign help.116 We are not told who his allies were; we can only guess that among them may have been the Burgundians, who, as we know, helped him at a later stage. The battle was fought on August 28; Odovacar was defeated and compelled to retreat. His next line of defence was on the Athesis (Adige), and he fortified himself in a camp close to Verona, with the river behind him.117 Here the second battle of the war was fought a month later (about Sept. 29)118 and resulted in a decisive victory for Theoderic. The carnage of Odovacar’s men is said to have been immense; but they fought desperately and the Ostrogothic losses were severe;119 the river was fed with corpses. The king himself fled to Ravenna. The greater part of the army, with Tufa who held the highest command, surrendered to Theoderic, who immediately proceeded to Milan.120
Northern Italy was now at the feet of the Goth; Rome and Sicily were prepared to submit, and it looked as if nothing remained to complete the conquest but the capture of Ravenna. But the treachery of Tufa changed the situation. Theoderic imprudently trusted him, and sent him with his own troops and a few distinguished Ostrogoths against Odovacar. At Faventia (Faenza) he espoused again the cause of his old master and handed over to him the Goths, who were put in irons.
Theoderic made Ticinum (Pavia) his headquarters during the winter, and it is said that one of his motives for choosing this city was to cultivate the friendship of the old bishop Epiphanius, who had great influence with Odovacar. In the following year Odovacar was able to take the field again, to seize Cremona and Milan, and to blockade his adversary in Ticinum. At this juncture the Visigoths came to the help of the Ostrogoths and sent an army into Italy. The siege was raised and the decisive battle of the war was fought on the river Addua (Adda), in which Odovacar was utterly defeated (Aug. 11, A.D. 490). He fled for the second time to Ravenna. It was probably this victory that decided the Roman Senate to abandon the cause of Odovacar, and accept Theoderic. It made him master of Rome, southern Italy, and Sicily.
The agreement that Zeno made with Theoderic had been secret and unofficial. The Emperor did nothing directly to break off his relations with Odovacar.121 But Odovacar seems some time before the battle of the Addua to have courted a formal rupture. He created his son Thela a Caesar, and this was equivalent to denouncing his subordination to the Emperor and declaring Italy independent.122 He probably calculated that in the strained relations which then existed between the Italian Catholics and the East, on account of the ecclesiastical schism, the policy of cutting the rope which bound Italy to Constantinople would be welcomed at Rome and throughout the provinces. The senators may have been divided on this issue, but the battle of the Addua decided them as a body to “betray” Odovacar,123 and before the end of the year Festus, the princeps of the Senate, went to Constantinople to announce the success of Theoderic, and to arrange the conditions of the new Italian government.
Theoderic confidently believed that his task was now virtually finished. But the cause of his thrice-defeated enemy was not yet hopelessly lost. Tufa was still at large with troops at his command; and other unexpected difficulties beset the conqueror. The Burgundian king Gundobad sent an army into North Italy and laid waste the country.124 Theoderic had not only to drive the invaders out, but he had also to protect Sicily against the Vandals, who seized the opportunity of the war to attempt to recover it. Their attempt was frustrated and they were forced to surrender the fortress of Lilybaeum as well as all their claims to the island.125
It seems to have been in the same year that Theoderic resorted to a terrible measure for destroying the military garrisons which held Italian towns for Odovacar. The Italian population was generally favourable to the cause of Theoderic, and secret orders were given to the citizens to slaughter the soldiers on a pre-arranged day. The pious panegyrist, who exultantly, but briefly, describes this measure and claims Providence as an accomplice, designates it as a sacrificial massacre”;126 and Theoderic doubtless considered that the treachery of his enemy’s army in surrendering and then deserting justified an unusual act of vengeance. The secret of the plot was well kept, and it seems to have been punctually executed. The result was equivalent to another victory in the field; and nothing now remained for Theoderic but to capture the last stronghold of his adversary, the marsh city of Honorius.
The siege of Ravenna lasted for two years and a half. The Gothic forces entrenched themselves in a camp in the Pine-woods east of the city, but were not able entirely to prevent provisions from reaching the city by sea. Yet the blockade was not ineffective, for corn rose to a famine price. One attempt was made by Odovacar to disperse the besiegers. He made a sortie at night (July 10, A.D. 491) with a band of Herul warriors and attacked the Gothic trenches. The conflict was obstinate, but he was defeated.127 Another year wore on, and it appeared that the siege might last for ever unless the food of the garrison could be completely cut off. Theoderic managed to procure a fleet of warships — we are not told whether they were built for the occasion,— and, making the Portus Leonis, about six miles from Ravenna, his naval base, he was able to blockade the two harbours of the city (August, A.D. 492).128 Odovacar held out for six months longer, but early in A.D. 493 negotiations, conducted by the bishop of Ravenna, issued in a compact between the two antagonists (February 25) that they should rule Italy jointly.129 Theoderic entered the city a week later (March 5).
The only way in which the compact could have been carried out would have been by a territorial division. But Theoderic had no mind to share the peninsula with another king, and there can hardly be a doubt that, when he swore to the treaty, he had the full intention of breaking his oath. Odovacar’s days were numbered. Theoderic, a few days after his entry into Ravenna, slew him with his own hand in the palace of Lauretum (March 15). He alleged that his defeated rival was plotting against him, but this probably was a mere pretext.130 “On the same day,” adds the chronicler, “all Odovacar’s soldiers were slain wherever they could be found, and all his kin.”131
In three years and a half Theoderic had accomplished his task. The reduction of Italy cost him four battles, a massacre, and a long siege. His capital blunder had been to trust Tufa after the victory of Verona. We may be sure that throughout the struggle he spared no pains to ingratiate himself in the confidence of the Italian population. But when his rival had fallen, and when he was at last securely established, Theoderic’s first measure
