The Ala was stationed in the province of Britannia . It is listed on military diplomas for the years 98/114 to 158 AD AD 132. The unit was probably set up under Augustus . It was probably stationed in Germania in the 1st century AD , since two of its soldiers were recruited from the Treveri tribe. The Ala may then have been part of the troops led by Aulus Plautius that began conquering Britain around 43 AD.
The first record in Britain is based on a diploma dated 98/114. The Diploma lists the Ala as part of the troops (see Roman forces in Britannia ) that were stationed in the province. Other diplomas dated 122 through 158 occupy the unit in the same province. The last evidence of the Ala is based on an inscription which is dated to 242.
Name parts of the Ala Augusta ob virtutem appellata
- Ala : The Ala was a cavalry unit of the auxiliary troops in the Roman army .
- I : The Roman numeral stands for the ordinal number, the first ( Latin prima ). Hence the name of this military unit is pronounced as Ala prima.
- Augusta : the Augustan. The honorific refers to Augustus .
- Gallorum : the Gaul . The soldiers of the Ala were recruited from the various tribes of the Gauls when the unit was formed.
- Proculeiana : of Proculeius. The cavalry units of the Gauls were often named after one of their first commanders. Gaius Proculeius is mentioned as a possible namesake . [A 2] The addition occurs in the military diplomas from 125 to 158.
- Gordiana : the Gordian. An honorific referring to Gordian III. (238-244) relates. The addition occurs in an inscription .
- ob virtutem apellata : awarded for bravery. The addition occurs in several inscriptions .
- Since there is no evidence of the suffix milliaria (1000 men), the unit was an Ala quingenaria . The nominal strength of the Ala was 480 men, consisting of 16 turmae , each with 30 horsemen.
Locations of Ala Augusta ob virtutem appellata in Britannia
Possibly at Lancaster in the late 1st century, first identified at Chesters on Hadrian’s Wall during Hadrianic period. The unit was likely removed from Chesters after the accession of Pius ( AD138) and campaigned somewhere in Scotland, the next known record of the unit being at Old Carlisle in 188, where it stayed until at least 242. The altar at Carlisle recording a victory won by the unit, probably belongs to the period when they were stationed nearby at Old Carlisle. The fate of this unit is unknown, but it may have been renamed Ala Augusta Gordia(na), also recorded at Old Carlisle.
Chesters (Cilurnum):Two inscriptions have been found here. Presumably the unit was stationed at Chesters around 132.

Possible Commanders of the Ala Ala Augusta ob virtutem appellata in Britannia
- Gaius Geminius Priscus, a prefect ( CIL 5, 6478)
Gaius Geminius Priscus was a member of the Roman equestrian order ( eques ) living in the 1st and 2nd centuries AD . Through an inscription from Laumellum, today’s Lomello , individual stations of his career are known, which he probably completed in the early 2nd century. The order of the offices held by Gaius Geminius Priscus is not clear from the inscription with his cursus honorum. It is most likely that he was initially assigned as praefectus fabrum to a magistrate or proconsul in one of the senatorial provinces of the Roman Empire. He then began his military career as prefect of the Cohors I Breucorum , stationed in the province of Raetia . However, this command was only given to him pro forma ( libero commeatu ), since he was probably staying somewhere else. This could either have been meant as a special privilege for Priscus  or indicate an extraordinary leave of absence. Thereafter he became prefect of an Ala Augusta . There were several units referred to in inscriptions as Ala Augusta . Geminius Priscus could therefore have commanded one of the following units: the Ala I Augusta Gallorum stationed in the province of Mauretania Tingitana , the Ala I Augusta Gallorum Proculeiana stationed in Britannia , or the Ala I Augusta Thracum stationed at the time of his command stationed either in Raetia or in Noricum. The last step in his career was then probably the command as tribune of the Cohors II Praetoria . However, this position is at the very end of the listing of the posts held in the inscription, although otherwise it appears to be a “descending” cursus honorum , i.e. the more important offices are named firstacts. In addition, the inscription stone has been lost and, at least according to the surviving signature, the word “tribune” was left out of the text. It has therefore also been assumed that his service in the Cohors II Praetoria was not at the end but at the very beginning of his career and that he worked there as a simple soldier. In that case , however, between this time and his appointment as praefectus fabrum he would first have had to be promoted to centurion and then to primus pilus.
- Lucius Egnatius Quartus, a prefect (Supplementum Epigraphicum Graecum 6 (1932), number 174. & Supplementum Epigraphicum Graecum 6 (1932), number 167.)
Lucius Egnatius Quartus ( full name form Lucius Egnatius Luci filius Teretina Quartus ) was a member of the Roman equestrian order ( eques ) living in the 2nd century AD . Individual stages of his career, which he probably completed in the first half of the 2nd century, are known from two inscriptions in Greek . His military career consisted of the tres militiae usual for a member of the equestrian order . First, as prefect , he took charge of the Cohors II Claudia , which was stationed in the province of Cappadocia . In the same province he also assumed the post of praepositus of the Ala I Augusta Gemina Colonorum as an extraordinary command . He then became tribune of the Legio VIII Augusta , stationed at Argentoratum in the province of Germania superior . The conclusion of his career, as far as it is known from the inscriptions, was the command as prefect of an Ala Augusta . However, it is not entirely clear which units of this name were involved in this case. However, since the epithet “Augusta”, unlike the Ala I Augusta Gemina Colonorum in the same inscription, was not translated into Greek as “Σεβαστή”, but simply transcribed in Greek script as “Αὐγούστη” , it can be assumed that it is is a unit stationed in the west of the Roman Empire, so more commonly known by its Latin name. Egnatius Quartus should therefore either be the Ala I Augusta Gallorum Proculeiana, stationed in the province of Britannia , or the Ala I Augusta Thracum , stationed in either Raetia or Noricum at the time of his command.
