units bearing the fort's name in connection with the Vicus Julius, in the Roman army in Gaul and stationed at Lutetia (modern Paris). This suggests that by the time the Notitia was written, the original garrison had been moved to Gaul and replaced with the numerus Abulcorum. The Abulci are mentioned in connection with the field army in Gaul and in the suppression of the rebellion of Magnentius in Pannonia Secunda in 351. It is not known whether their name is a geographical or functional one but their description by Zosimus suggests that they were an elite body of troops, who served both in the field army and, probably in the form of a single detachment, at Anderitum. They may have been foederati, troops raised from allied barbarian tribes and put under the command of a Roman prefect, or perhaps even a single band of warriors with their own leader. Similar numeri were recorded in the Notitia Dignitata as being stationed in other Saxon Shore forts. Abandonment and post-Roman use Unlike at many other Roman forts, no civilian settlement or vicus appears to have been established outside the walls of Pevensey Castle; this was probably because the fort was at the end of a peninsula with limited room for additional construction. When the Roman army retreated from Britain in 410, civilians appear to have moved into the abandoned fort, perhaps for protection against Saxon raiders, and its name continued to be used well into the Saxon period. According to the Anglo-Saxon Chronicle, in 477 a Saxon raid drove local people into the forest of Andreadsleag (which from another reference seems to have stretched over from the mouth of the River Lympne to Hampshire). Although the history of the fort at this time is unrecorded, archaeological evidence indicates that its inhabitants had wide-ranging trade links that enabled them to import wares from as far afield as Macedonia and Syria. They may have exported timber and iron from the Sussex Weald to pay for such costly goods. In 491, the Chronicle records that the Saxons Aelle and Cissa "besieged Andredadsceaster and slew all the inhabitants; there was not even one Briton left there." It is uncertain whether habitation of the fort continued after this event, which is now thought to have happened around 471 rather than the date recorded by the Chronicle (due to a dating error by Gildas, on whose work
