. Soldiers would have worn a similar panoply to this. 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. Valens' army included units of veterans, men accustomed to war. The entire force consisted of seven
legions – 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). ''. Ammianus Marcellinus makes references to the following forces under Valens: • Legions of
Lanciarii, and
Mattiarii. The 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: •
Ricomer, 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.
Strength of Valens' army Several modern historians have attempted to estimate the strength of Valens' army. Warren Treadgold estimates that, by 395, the Army of Thrace had 24,500 soldiers, while the 1st and 2nd Armies in Emperor's Presence had 21,000 each. However, all three armies include units either formed (several units of
Theodosiani among them) or redeployed (various legions in Thrace) after Adrianople. ==Composition of the Gothic forces==
