Battle of Adrianople

In 376, the Goths, led by Alavivus and Fritigern, asked to be allowed to settle in the Eastern Roman Empire after being displaced by the invasions of the Huns. Hoping that they would become farmers and soldiers, the Eastern Roman emperor Valens allowed them to establish themselves in the Empire as allies (foederati). Once across the Danube and into Roman territory, however, the dishonesty of the Roman provincial commanders Lupicinus and Maximus led the newcomers to revolt after suffering many hardships. Valens then asked Gratian, the western emperor, for reinforcements to fight the Goths. Gratian sent the general Frigeridus with reinforcements, as well as the leader of his guards, Richomeres. For the next two years preceding the battle of Adrianople there were a series of running battles with no clear victories for either side.[10]

In 378, Valens decided to take control himself and assembled additional troops from his own resources in Syria and from the reserves of the Western Empire in Gaul.[11]

Valens left Antioch for Constantinople, and arrived on 30 May. He appointed Sebastianus, newly arrived from Italy, to reorganize the Roman armies already in Thrace. Sebastianus picked 2,000 of his legionaries and marched towards Adrianople. Along the way, they came upon and ambushed small detachments of Goths. Fritigern as the leader of the Goths assembled his forces at Nicopolis and Beroe (now Stara Zagora) in order to deal with the Roman threat.[8][12][13]

At the time, much of Gratian's army was in Pannonia where they were in the interm attacked across the Rhine by the Lentienses (part of the Alamanni). After the Romans regrouped and defeated the Lentienses near Argentaria (near modern-day Colmar, France), Gratian's army traveled east partly by sea and partly overland.[8][14]

Upon learning of Sebastian's success against the Goths and of Gratian's victory over the Lentienses, Valens was more than ready for a victory of his own. To link up with Sebastian's forces before confronting the Goths, Valens moved his army from Melantias to Adrianople. On 6 August, reconnaissance informed Valens that approximately 10,000 Goths were advancing toward Adrianople from a position 25 kilometers to the north. In preparation at Adrianople, Valens fortified his camp with both ditches and ramparts.[15]

Richomeres, sent in advance to Adrianople by Gratian, carried a letter asking Valens to wait for his arrival with reinforcements before engaging in battle. Valens' officers also recommended that he wait for Gratian, but Valens decided to fight without waiting, ready to claim the ultimate prize.[15]

The Goths were also watching the Romans, and on 8 August, Fritigern sent an emissary to propose peace and an alliance in exchange for Roman territory. Sure that he would be victorious due to his supposed numerical superiority, Valens rejected these proposals.[15] Valens' estimates of manpower, however, neglected to take into consideration part of the Gothic cavalry that had gone extended distances to forage.[16]

Valens' army may have included troops from three Roman field armies: the Army of Thrace, based in the eastern Balkans, which may have sustained heavy losses in 376–377; the 1st Army in the Emperor's Presence; and the 2nd Army in the Emperor's Presence. Both armies in the Emperor's Presence were normally based at Constantinople in peacetime but had been committed to the Persian frontier in 376 and sent west in 377–378.[17][18]

Valens' army included units of veterans, men accustomed to war. The entire force consisted of seven legions[19] – among which were the Legio I Maximiana and imperial auxiliaries – of 700 to 1000 men each. The cavalry was composed of mounted archers (sagittarii) and Scholae (the imperial guard). These forces, however, attacked precipitately, while peace negotiations were being conducted, and ultimately fled. There were also squadrons of Arab cavalry, but they were more suited to skirmishes than to pitched battle.

Ammianus Marcellinus makes references to the following forces under Valens:

• Legions of Lanciarii, and Mattiarii. The Notitia Dignitatum lists both as legiones palatinae. Some claim that the Mattiarii may have been allied forces. However, mattiarii may refer to mace-armed infantry (mattea being Latin for mace). Valens is referred to as seeking protection with the Lanciarii and Mattiarii as the other Roman forces collapsed (apparently a sign of how desperate the battle had become). Eventually they were unable to hold off the Goths.
• A battalion of Batavians; they were apparently held in reserve and fled, given a reference to a comes named Victor attempting to bring them up into battle but unable to find them.
• Scutarii (shielded cavalry) and archers. As one or both were under the command of Bacurius the Iberian, these may have been allied auxiliary troops from Caucasian Iberia (part of modern Georgia) rather than Roman proper.

He also refers to the following officers:

• Ricimer (Richomeres), Frankish Comes of Gratian's Domestici (the corps of bodyguards of the emperor who were stationed in the imperial palace) sent to assist Valens in 376. He offered to act as a hostage to facilitate negotiations when Equitus refused. He survived the battle, indicated due to retreating.
• Sebastianus, arrived from Italy previously, and clearly operating as one of Valens' generals. Killed in the battle.
• Victor, master-general of the cavalry, a Sarmatian by birth, who led the officers counselling waiting for Gratian.
• Equitius, a relation of Valens, a tribune and high steward of the palace. He refused to act as a hostage, as he had been a prisoner of the Goths in Dibaltum and escaped, and now feared revenge. Killed in the battle.
• Bacurius (presumably Romanised Bakur), a native and possibly prince of Iberia, in command of the archers and/or scutarii with Cassio that accompanied Ricimer as hostage, and who attacked without orders.
• Traianus, apparently in command of Roman forces before Valens assumed command, who was described as an illustrious man whose death in the battle was a great loss. He was supposedly still alive when Valens sought refuge with the Lanciarii and Mattiarii.
• Victor, the comes who tried to bring the Batavian reserve battalion into action.
• Cassio, in command of the archers and/or scutarii accompanying Ricimer as hostage.
• Saturninus, magister militum vacans, referred to as being able to stay alive by retreating.
• Valerianus, Master of the Stable. Killed in battle.
• Potentius, tribune of the Promoti, a branch of the cavalry, son of Ursicinus, former commander of the forces. He "fell in the flower of his age, a man respected by all persons of virtue."
• Thirty five tribunes, including those of units and those of the staff, who were killed. Presumably there were more than this, but who survived.

There were probably two main Gothic armies south of the Danube. Fritigern led one army, largely recruited from the Therving exiles, while Alatheus and Saphrax led another army, largely recruited from the Greuthung exiles. Fritigern brought most if not all of his fighters to the battle and appears to have led the force the Romans first encountered. Alatheus and Saphrax brought their cavalry into action "descending like a thunderbolt" against the Romans. These forces included Alans.

The Gothic armies were mostly infantry, with some cavalry, which was significant in the battle of Adrianople. Some older works attribute the Gothic victory to overwhelming Gothic numbers, to Gothic cavalry, and sometimes to Gothic use of stirrups.[23] More recent scholarly works mostly agree that the armies were similarly sized, that the Gothic infantry was more decisive than their cavalry and that neither the Romans nor the Goths used stirrups until the 6th century,[24] probably brought by the Avars.[25]

Ammianus records that the Roman scouts estimated 10,000 Gothic troops, but Ammianus dismissed this as an underestimate.[15] This appears to be due to Alatheus and Saphrax's forces being away when the Roman scouts estimated the Goths' numbers before battle. Several modern historians have estimated the strength of the Gothic armies at 12,000–15,000.[26]

Ammianus notes the important role of the Gothic cavalry. Charles Oman, believing that the cavalry were the majority of the Gothic force, interpreted the Battle of Adrianople as the beginning of the dominance of cavalry over infantry for the next thousand years.[27] Some other historians have taken the same view.[28] Burns and other recent historians argue that the infantry were the vast majority of the Gothic force, and that the battle had little effect on the relationship between infantry and cavalry.[29]

The battle took place within a few hours' march of the city of Adrianopolis, but its precise location is uncertain. Three possible locations of the battle have been discussed in modern historiography:

• One thesis suggests that the Gothic camp and the battleground were located to the north of Adrianopolis, west of the Tonzos river but east of Hebros river (41.81°N 26.50°E / 41.81; 26.50).[30][31]
• Another locates the battlefield again north of the city, but east of Tonzos river, near the contemporary Turkish village of Muratçalı (41.81°N 26.60°E / 41.81; 26.60).[32][33]
• The third thesis adopts a location east of the city, near the contemporary Turkish village of Demirhanlı (41.70°N 26.74°E / 41.70; 26.74), i.e. assuming that Valens was marching due East, starting from the Adrianople city walls.[34][35][36]

On the morning of 9 August, Valens decamped from Adrianople, where he left the imperial treasury and administration under guard. The reconnaissance of the preceding days informed him of the location of the Gothic camp north of the city. Valens arrived there around noon after marching for eight miles over difficult terrain.[37]

The Roman troops arrived tired and dehydrated, facing the Gothic camp that had been set up on the top of a hill. The Goths, except for their cavalry, defended their wagon circle, inside of which were their families and possessions. Fritigern's objective was to delay the Romans, in order to give enough time for the Gothic cavalry to return. The fields were burnt by the Goths to delay and harass the Romans with smoke, and negotiations began for an exchange of hostages. The negotiations exasperated the Roman soldiers who seemed to hold the stronger position, but they gained precious time for Fritigern.

Some Roman units began the battle without orders to do so, believing they would have an easy victory, and perhaps over-eager to exact revenge on the Goths after two years of unchecked devastation throughout the Balkans. The imperial scholae of shield-archers under the command of the Iberian prince Bacurius attacked, but lacking support they were easily pushed back. Then the Roman left wing reached the circle of wagons, but it was too late. At that moment, the Gothic cavalry, returning from a foraging expedition, arrived to support the infantry. The cavalry surrounded the Roman troops, who were already in disarray after the failure of the first assault. The Romans retreated to the base of the hill where they were unable to maneuver, encumbered by their heavy armor and long shields. The casualties, exhaustion, and psychological pressure led to a rout of the Roman army. The cavalry continued their attack, and the killing continued until nightfall.

In the rout, the Emperor himself was abandoned by his guards. Some tried to retrieve him, but the majority of the cavalry fled. Valens' final fate is unknown; he may have died anonymously on the field. His body was never found. An alternative story circulated after the battle that Valens had escaped the field with a bodyguard and some eunuchs and hid in a peasant's cottage. The enemy attempted to pillage the cottage, apparently unaware Valens was inside. Valens' men shot arrows from the second floor to defend the cottage and in response the Goths set the cottage on fire. The bodyguard leaped out the window and told the Goths who was inside, but it was too late. Valens perished in the flames.[38]

According to the historian Ammianus Marcellinus, the Goths immediately marched to the city of Adrianople and attempted to take it; Ammianus gives a detailed account of their failure. Ammianus refers to a great number of Roman soldiers who had not been let into the city and who fought the besieging Goths below the walls. A third of the Roman army succeeded in retreating, but the losses were uncountable. Many officers, among them the general Sebastian, were killed in the worst Roman defeat since the Battle of Edessa, the low point of the Crisis of the Third Century. The battle was a crushing blow for the late Empire, resulting in the destruction of the East Roman army's core, the deaths of valuable administrators, and the destruction of nearly all armories on the Danubian provinces following the battle. The lack of reserves for the army worsened the recruitment crisis. Despite the losses, the battle of Adrianople did not mark the end of the Roman Empire because the imperial military power was only temporarily crippled.

The defeat at Adrianople signified that the barbarians, fighting for or against the Romans, had become powerful adversaries. The Goths, though partly tamed by Valens' successor Theodosius I (who accepted them once more as allied tribes), were never expelled, exterminated, or assimilated; they remained as a distinct entity within its frontiers, for a few years allies, later semi or fully independent or often hostile.

The long-term implications of the battle of Adrianople for the art of war have often been overstated, with many 20th-century writers repeating Sir Charles Oman's idea[39] that the battle represented a turning point in military history, with heavy cavalry triumphing over Roman infantry and ushering in the age of the medieval knight. This idea was disputed by T. S. Burns in 1973.[40] According to Burns, the Gothic army's cavalry arm was fairly small, that Valens would actually have had more cavalry and that while the role of Fritigern's cavalry was critical to his victory, the battle was a mainly infantry versus infantry affair. The medieval knight was not to rise for several centuries after Adrianople.
