We hear no more of this war till after that great insurrection of the Roman provincials under Boadicea or Bondiuca, queen of the Iceni, which shook the Roman power in Britain to its foundation, and had nearly resulted in their entire expulsion from the island. A struggle such as the language of the historians shows this to have been must necessarily have been a vital one on both sides; and hence, when the Roman arms eventually prevailed, the result produced a firm consolidation of their power in that part of the island which formed the Roman province. The immediate subject before us—the extension of the Roman power towards the north, and the gradual advance of the northern frontier of the province—renders it unnecessary for us to dwell with any minuteness upon their contests with the native tribes in other quarters. It is sufficient to notice that Veranius succeeded Aulus Didius, but died within the year, and that under Suetonius Paulinus, one of the most distinguished of the Roman commanders in Britain, and the governor by whom the great insurrection of the Iceni was finally quelled, the western tribes were finally brought under the dominion of the Romans. [Sidenote: A.D. 69. War with the Brigantes renewed.] We find the Brigantes again in hostility to the Romans during the government of Vettius Bolanus, which commenced in the year 69. Venusius appears to have maintained an independent position and a hostile attitude towards the Romans throughout, and a lengthened civil war had continued to prevail between his adherents and that part of the nation which remained subject to Cartismandua, and in this war the Romans once more took part under Vettius Bolanus. Venusius was at the head of a powerful army, and the subjects of the queen flocked daily to his standard. Cartismandua was reduced to the last extremity, and invoked the protection of the Romans, who sent troops to her assistance. The war was prosecuted with varied success; many battles were fought; but Venusius succeeded in obtaining the throne of the whole nation.[34] Under Petilius Cerealis, the successor of Vettius Bolanus, who was sent by the Emperor Vespasian to reduce the Brigantes, the war was brought to a conclusion. With the assistance of a powerful army, which struck terror into the natives, he attacked the whole nation of the Brigantes; and, after a struggle, in which various battles were fought and much slaughter took place, he subjected the greater part of the extensive territory in the possession of that powerful nation to the Romans. This conquest was maintained by his successor Julius Frontinus.[35]
