Consort of the redoubtable Cartimandua, queen of the Brigantes, seems at first to have concurred with her pro-Roman policy, but by ad 69 had abandoned it. The breakdown of the royal marriage was accompanied by civil war, in which his queen had to be rescued by the Romans. Venutius remained in control of the Brigantes. In 72 Petillius Cerialis led an expedition against him; Venutius seems to have fallen back on his capital at Stanwick and heavy fighting took place. He may have retreated further into the Cumbrian hills and certainly lost his grip on his former territories. Tacitus praised his military skill.
