The campaigns of this governor are detailed by the Roman historian Cornelius Tacitus in his Annals of Rome (book XII, chapter xl-xli), also in his Histories (book III, chapter xliv). The campaigns of Didius Gallus are covered in chapter 5 of Rome Against Caratacus by Graham Webster (Batsford, London, 1981).
The last governor Ostorius Scapula had been killed while on campaign against the Silures in South Wales and Didius Gallus was sent by emperor Nero with all haste to assume command of Britain. Shortly before his arrival in the province the tribe had attacked and badly mauled a Roman legion encamped within thier territories which, although unnamed by Tacitus, was most likely Legio XX Valeria, which had been redeployed into the area by the previous governor to deal with the warlord Caratacus. These circumstances obliged Gallus to commence his administration with a swift retributive action against the Silures, which appears to have been accomplished very swiftly indeed, leaving behind no permanent encampments and no temporary marching camps in Silurian territory which may be positively dated to the period.
The ongoing campaign against the Silures was, however, soon overshadowed by political machinations within the powerful tribe in northern England. The queen of this tribe, Cartimandua, had been recognised as a ‘client’ of Rome and, honouring her obligations in this regard, she had handed the British warlord [link_post post_id="1363"] over to the Roman administration in 50AD. This action had stirred-up no small amount of unrest within the tribe, and with the major anti-Roman faction being led by the prince-consort Venutius, it was only a matter of time before the situation became critical.
Sometime during the tenure of Gallus, the [link_post post_id="1312"] broke into civil war, the northern, anti-Roman faction led by Venutius, the southern, pro-Roman faction led by Cartimandua. The tide of the intertribal war in the north ebbed first one way then the other, with hostages being taken and skirmishes being fought, finally resulting in the ageing queen being rescued by a timely Roman intervention.
To contain the situation on the northern borders of the Roman province the Ninth Hispanic Legion was redeployed into campaign/vexillation fortresses on the western borders of the [link_post post_id="1316" type="link"]Coritani tribe at Osmanthorpe in Nottinghamshire and Newton-on-Trent in Lincolnshire; one of these vexillations appears to have been relocated further north to Rossington Bridge in South Yorkshire, perhaps as better information on the extent of the Brigantian unrest was obtained. At the same time Legio XIV Gemina was redeployed into campaign fortresses just within the north-eastern borders of the Cornovii tribe at Wall and Kinvaston, both sited along the Watling Street in South Staffordshire.
It appears likely that the fort at Littlechester in Derbyshire, along with the fortlets at Broxtowe in Nottinghamshire and Marton in Lincolnshire, were established at this time to facilitate communications between these frontier units. The establishment of another auxiliary fort on the Fosse Way at East Stoke in Nottinghamshire, close to the Osmanthorpe fortress, may indicate that it was the garrison here which was removed to the Rossington site, with the site on the Fosse Way being established to maintain the communication link between the two legionary groups.
The Roman interest in the lead/silver mines at Pentrich in the Lower Pennines of Derbyshire is demonstrated by the establishment at this time of a small military station overlooking the mine-workings here.
