While the southern province was scourged by Viriathus and the Lusitanians, a second and not less serious war had, not without their help, broken out in the northern province among the Celtiberian nations. The brilliant successes of Viriathus induced the Arevacae likewise in 610 to rise against the Romans; and for this reason the consul Quintus Caecilius Metellus, who was sent to Spain to relieve Maximus Aemilianus, did hot proceed to the southern province, but turned against the Celtiberians. In the contest with them, and more especially during the siege of the town of Contrebia which was deemed impregnable, he showed the same ability which he had displayed in vanquishing the Macedonian pretender; after his two years' administration (611, 612) the northern province was reduced to obedience. The two towns of Termantia and Numantia alone had not yet opened their gates to the Romans; but in their case also a capitulation had been almost concluded, and the greater part of the conditions had been fulfilled by the Spaniards. When required, however, to deliver up their arms, they were restrained like Viriathus by their genuine Spanish pride in the possession of a well- wielded sword, and they resolved to continue the war under the daring Megaravicus. It seemed folly: the consular army, the command of which was taken up in 613 by the consul Quintus Pompeius, was four times as numerous as the whole population capable of bearing arms in Numantia. But the general, who was wholly unacquainted with war, sustained defeats so severe under the walls of the two cities (613, 614), that he preferred at length to procure by means of negotiations the peace which he could not compel. With Termantia a definitive agreement must have taken place. In the case of the Numantines the Roman general liberated their captives, and summoned the community under the secret promise of favourable treatment to surrender to him at discretion. The Numantines, weary of the war, consented, and the general actually limited his demands to the smallest possible measure. Prisoners of war, deserters, and hostages were delivered up, and the stipulated sum of money was mostly paid, when in 615 the new general Marcus Popillius Laenas arrived in the camp. As soon as Pompeius saw the burden of command devolve on other shoulders, he, with a view to escape from the reckoning that awaited him at Rome for a peace which was according to Roman ideas disgraceful, lighted on the expedient of not merely breaking, but of disowning his word; and when the Numantines came to make their last payment, in the presence of their officers and his own he flatly denied the conclusion of the agreement. The matter was referred for judicial decision to the senate at Rome. While it was discussed there, the war before Numantia was suspended, and Laenas occupied himself with an expedition to Lusitania where he helped to accelerate the catastrophe of
