In early 538 and during the Siege of Rome (537–538), the besieged Byzantine General Belisarius sent John the Sanguinary to raid Picenum. John took the initiative and captured Ariminum, which was near the Gothic capital in Ravenna, to entice the Goths into lifting the siege of Rome. Belisarius sent reinforcements to Ariminum and ordered John to leave the city, as his cavalry forces would not be useful in the case of a siege. However, John refused to obey and stayed in the city. In the meantime, fearing for their capital, the Goths retreated from Rome and moved to besiege Ariminum in March 538. They were unsuccessful in taking Ariminum by force, and instead, the leader of the Gothic forces, Vitiges, decided to starve the town.
Initially, the Byzantine leadership was divided over whether to rescue John despite his insubordination. Belisarius ultimately chose to save him after an appeal from Chamberlain Narses that John's loss would boost the morale of the Goths. Belisarius wanted to avoid direct battle engagement because the Goths outnumbered the Byzantine forces. He split his army into smaller groups and sent them to Ariminum by land and sea. The near-simultaneous arrival of Byzantine forces from multiple directions created the impression of a much larger army, unnerving the Goths. As a result, they abandoned the siege on 24 July 538 and withdrew to Ravenna. Despite the victory, disagreements over John's insubordination fractured the unity of the Byzantine leadership.
Primary sources
Procopius of Caesarea is the major Greek historian of Late Antiquity and the main source for Justinian's reign.[8] In the Books V–VIII of the Wars, Procopius described the Gothic War (535–554), and it is largely paraphrased by modern scholarship as it is the sole source that covered these events.[9] He was Belisarius's assessor, being an eyewitness to military engagements, having access to official information, and knowledge of military affairs. These advantages placed him in a unique position to reconstruct the wars in the East, Africa, and Italy.[10] He adopted a classical style in narrating the events, inspired by historians such as Thucydides and Herodotus, by prioritizing speeches, moral explanation, and dramatic structure over strict documentary accuracy.[11]
Procopius's work is largely factual, and even though he was on the Byzantine side, it is neither entirely neutral nor propaganda. He portrayed Belisarius favorably over other Byzantine commanders, reflecting personal loyalty, and disproportionately emphasized mounted combat, marginalizing the role of infantry in battles and sieges.[12] His view of Justinian ranges from enthusiasm and optimism in the first part of the Wars to open hostility in the Secret History.[11] Even in the Wars, there is a transition at the point when Belisarius left Italy in mid-summer 540 AD, presumably due to Belisarius's unbroken loyalty to Justinian, followed by the resurgence Gothic resistance led by charismatic Totila, who became the protagonist and a tragic hero in Procopius's narrative in the latter part of the Gothic War.[13]
Background
In 476 AD, the last western Roman emperor, Romulus Augustulus, was deposed and authority passed to the Germanic general Odoacer, though he nominally recognized the supremacy of the Byzantine emperor in Constantinople.[14] In 493, Odoacer was overthrown and killed by Theodoric the Great, who sought the creation of an independent kingdom by balancing the Gothic military dominance with the preservation of Byzantine civil institutions. For several decades, Theodoric's regime maintained relative stability, fostering cooperation between the senatorial elite in Rome and the Gothic ruling class.[15] The Byzantines were unable to interfere in the Italian peninsula. While Theodoric asked the then Byzantine Emperor Zeno permission to wear the royal regalia, the emperor died in 491 before deciding. Similarly, Emperor Anastasius initially did not consent, but in 497 accepted the usurpation. Theodoric used the titles rex and princeps (first citizen) and before his death, the Ostrogothic kingdom was the strongest barbarian nation occupying lands of the Western Roman Empire.[16]
After Theodoric's death in 526, his daughter, Amalasuntha, attempted to continue pro-Byzantine policies and maintain close ties with Byzantium under Emperor Justinian I. Her reliance on Byzantine advisers and her son's Byzantine education and the assassination of her political opponents to maintain her position as regent until her son came of age,[17] however, alienated segments of the Gothic nobility. Her son died in 534, prompting the opposition to bring up the succession question.[18] Soon after Amalasuntha was deposed and later murdered by Theodahad in 535, Justinian considered this as a casus belli justification to intervene militarily in Italian peninsula. Framing his campaign as both a defense of a legitimate ruler and a restoration of imperial authority, he launched a military campaign that became known as the Gothic War.[17][19]
At the time, the Byzantines had successfully conquered North Africa in the Vandalic War (533–534) and made preparations against the Goths. Following the fallout with Theodahad, Justinian opened two fronts against the Goths in 535. Specifically, Belisarius conquered Sicily and then southern Italian Peninsula with limited resistance, while Mundus and later Constantinianus seized Salona at Dalmatia.[20] The Goths failed to counter the Byzantine offences, while at the same time, Theodahad was in secret negotiations with Justinian.[21] The capture of Naples by Belisarius in 536, prompted the assassination of Theodahad by the men of Vitiges.[22] Belisarius entered Rome on 9 December 536.[23]
Prelude
Siege of Rome
In response to the loss of Rome, Vitiges, as the new king of the Goths, marched with an army that had superior numbers[c] to besiege the city. The Siege of Rome (537–538) featured repeated Gothic assaults on Rome's walls, countered by Belisarius's defensive preparations, use of artillery, and cavalry sorties that exploited the Goths' difficulties in countering mounted archers. Both sides suffered from shortages and disease, but Byzantine control of sea supply routes gradually weakened the besieging Goths, who faced greater logistical challenges in supplying their large army by land.[30]
Capture of Ariminum
In March 538, and while the siege of Rome was ongoing, Belisarius sent John, nephew of the Byzantine general Vitalianus, to raid Picenum. John defeated the Gothic commander Ulitheus (uncle of Vitiges[31]) in battle, gaining a reputation among the Goths. He ignored the cities of Auximus and Urbinus due to their strong garrisons. When he approached Ariminum, its citizens invited John to take the town. John realized the importance of Ariminum, which was one to two days' march away from the Gothic capital of Ravenna, and its capture would force Vitiges to lift the siege of Rome.[32][33] The Gothic garrison retreated from Ariminum to Ravenna "as soon as they learned that [John's] army was approaching", and John took the city without resistance.[34] In the meantime, Vitiges' wife, Mataswintha, opened negotiations with John and proposed the idea of marriage, on account of Vitiges marrying her by force. John's reputation was bolstered by the town's capture, and according to Procopius, John and Mataswintha frequently exchanged messages.[34]
The Goths, upon hearing the fall of Ariminum, lifted the siege of Rome and traveled towards Ravenna. Their travel was slow because they moved as a large army and took detours to avoid the Byzantine fortresses at Narnia, Spoletium, and Perusia.[35]
John's insubordination
Belisarius, anticipating that the Goths would attempt to besiege Ariminum, sent infantry forces to replace John and his cavalry unit, ordering John along the Via Flaminia with a thousand horsemen to arrive in Ariminum before the retreating Goths did.[36] Belisarius's order was motivated by two reasons: first, the Goths would not consider a small garrison with an unknown commander as a threat and focus their attention elsewhere. Second, John's cavalry would not be as effective in a siege as it was when it was harassing the Goths in the open, and during a siege the horses would also consume additional food.[37][38] However, John disobeyed the orders and stayed in Ariminum with the infantry reinforcements sent by Belisarius.[39][40][41]
At Firmum Belisarius met Chamberlain (Cubicularius) Narses, who had arrived with reinforcements from Constantinople. They convened a council of officers to decide whether the army should march to John's aid in Ariminum. Most of the officers opposed helping John, resentful of his challenge to Belisarius's authority. Narses, however, appealed to Belisarius and his officers to carry out the rescue.[41]
Now if John treated your commands with insolence, most excellent Belisarius, the atonement you have already exacted from him is surely ample, since it is now in your power either to save him in his reverse or to abandon him to the enemy. But see that you do not exact from the emperor and from us the penalty for mistakes committed by John through ignorance. For if the Goths capture Ariminum at the present juncture, it will be their good fortune to have made captive a capable Byzantine general, as well as a whole army and a city subject to the emperor.[41][42]
Narses' argument and John's message stating that he would be forced to surrender to the Goths in seven days if there was no support, convinced Belisarius to rescue John and Ariminum.[41]
Army movements and engagements
Siege
Vitiges besieged the town of Ariminum upon the arrival of the Gothic forces. They built a siege tower which, unlike during the siege of Rome, was not pulled by oxen, but moved by men stationed inside. The tower was placed relatively close to the wall with the expectation that it would be used the following day. During the night, the Byzantines sortied out of the town to dig a trench in front of the siege tower. When the Goths found out, they attacked the Byzantines, who retreated as soon as the trench was deep enough. In response, Vitiges had the trench filled with faggots before moving the siege over it. The weight of the tower caused it to sink slightly into the trench as the faggots were crushed and the earthwork, made of the dirt out of the trench, which was built behind it, stopped the advance entirely.[43][44] Vitiges ordered that the night guards responsible for this setback be executed.[45]
Vitiges decided to withdraw, taking the tower with him. John wanted to prevent this and sallied out, but was unsuccessful at destroying the siege tower. Having suffered many casualties, Vitiges decided against storming Ariminum and began starving it out.[43] Needing fewer men for this, he also sent men to attack Ancon.[46]
Belisarius' deception
Belisarius wanted to avoid actual fighting because the Goths outnumbered the Byzantines. He split his army into smaller groups, three of which were sent to the vicinity of Ariminum. The central idea was to surround the Goths from three sides, leaving only one safe passage to escape.[47] One group, led by Ildiger, was to move by sea, accompanied by a group led by Martinus on land. Meanwhile, Belisarius and Narses came through the Apennines, passing Urbisaglia. Their forces encountered a group of Gothic soldiers, who were defeated. The survivors fled back to the Gothic camp and claimed that the Byzantines were approaching with a large force from the north. This led the Goths to move their camps to the north of Ariminum.[48][47]
In the meantime, Martinus' forces approaching from the south lit numerous campfires at night, which projected a larger force than the true Byzantine strength.[47] The appearance of the Byzantine fleet further shook the Goths. On 24 July 538, the Goths lifted their siege of Ariminum and moved to Ravenna. Belisarius and his army entered Ariminum around noon.[49]
Aftermath
After the siege, John declined to express any gratitude to Belisarius and instead claimed that Narses deserved the credit because it was Narses who had compelled Belisarius to come to his rescue.[49] Narses and John, along with their supporters, withdrew from the main army and acted independently from Belisarius. Byzantine forces, unable to act together due to division in their leadership, became ineffective. Poor coordination led to the loss of the major city of Mediolanum (modern day Milan) to the Goths in early 539. Procopius recorded that the Goths executed 300,000[d][51] men, sold the city's women to Burgundians, and razed the city to the ground.[52][50] In response to this setback, Emperor Justinian called Narses back to Constantinople, leaving Belisarius as the sole commander-in-chief of the Byzantine forces in Italy.[53]
In 539, Belisarius proceeded to secure strongholds in the surrounding region of Ravenna. With the fall of Auximus, he advanced to besiege Ravenna, aiming to starve the garrison since the city had strong defensive advantages. While the Goth nobility negotiated their surrender and Justinian was willing to offer generous terms, Belisarius employed a stratagem of inducing the Goths to surrender by offering him the Western Roman imperial crown. At the last moment, he refused the crown, but at this moment the Byzantine troops were in control of the city and capturing the Gothic king. The fall of Ravenna concluded the first phase of the Gothic War, with most of Italy under Byzantine control. The stratagem spooked Justinian. Although Belisarius returned to Constantinople in mid-summer 540 with the Ravenna's treasury and the defeated Gothic King Vitiges as prisoner, Justinian refused him a triumph. The general's departure was also needed on the eastern front against the Persians in the upcoming Lazic War (541–562).[54] However, the premature departure of Belisarius and the failure of Justinian in appointing a sole commander-in-chief in Byzantine forces in Italy reignited the Gothic resistance and prolonged the Gothic War by more than a decade.[55]
Scholarly assessment
Historians argued that Belisarius's actions during the Siege of Ariminum are notable primarily for achieving victory without a fight against a numerically superior adversary. Specifically, they praise his ability as a commander to anticipate the enemy's reactions and, through strategy and psychological warfare, make maximum use of the forces available to him to achieve success.[56][57] Historian J. B. Bury said about the siege of Ariminum, "when Belisarius set his mind to the problem he solved it triumphantly."[58] Historian Ilkka Syvänne placed the break of the Siege of Ariminum as a prime example of Sun Tsu's principle of "Subjugating the enemy without fighting is the true pinnacle of excellence."[59]
