"Next Didius Gallus maintained the ground gained by his predecessors, and pushed forward a few forts into remoter districts in order to gain credit for enlarging his province."
The province had suffered since the unexpected death of the previous governor Ostorius Scapula, and a legion, perhaps the Twentieth, had suffered a defeat in battle against the Silures in south Wales. Gallus possibly established the large legionary base at Wroxeter in the Central Welsh Marches to stabilise the Welsh frontier. In the latter part of his governorship Gallus was called upon to settle a violent internal dispute among the Brigantes tribe in northern England, when the prince consort Venutius turned against his spouse Cartimandua, and several auxiliary cohorts had to be sent to the client-queen's rescue. Talk in Rome at this time was of a complete withdrawal from Britain, and the emperor's tutor and adviser Seneca began to call in the loans he had made to many British chiefs, fuelling anti-Roman feelings in the south-eastern part of the province while Gallus was busy campaigning against the Welsh tribes.
A short chapter outlining Gallus' actions during his governorship of Britain can be found in the Annals of Tacitus (book 12, chapter 40), which implies that he was already an old man when he took the helm of the British province.
"... Didius, burdened with years and covered with honours, was content with acting through his officers and merely holding back the enemy. ..."
