78
Following the successful suppression of Boudica, a number of new Roman governors continued the conquest by edging north. Cartimandua was forced to ask for Roman aid following a rebellion by her husband Venutius. Quintus Petillius Cerialis took his legions from Lincoln as far as York and defeated Venutius near Stanwick around 70. This resulted in the already Romanised Brigantes and Parisii tribes being further assimilated into the empire proper. Frontinus was sent into Roman Britain in 74 AD to succeed Quintus Petillius Cerialis as governor of that island. He subdued the Silures and other hostile tribes of Wales, establishing a new base at Caerleon for Legio II Augusta and a network of smaller forts fifteen to twenty kilometres apart for his auxiliary units. During his tenure, he probably established the fort at Pumsaint in west Wales, largely to exploit the gold deposits at Dolaucothi. He retired in 78 AD, and later he was appointed water commissioner in Rome. The new governor was Gnaeus Julius Agricola, made famous through the highly laudatory biography of him written by his son-in-law, Tacitus.
