The Carthaginians were finally driven from Spain in 206. We may pass quickly over the next fifty years. By degrees the Roman power advanced till the whole peninsula, some mountainous regions in the north and centre excepted, became subject to it. Rebellions were frequent, for the Roman system was to change the provincial governors almost from year to year, and some of these officials were cruel and extortionate. As I am not writing a history either of Rome or of Spain, I must limit myself to the most important and representative persons and events. Viriathus was a native of Lusitania, a region nearly corresponding to what is now called Portugal. His hatred of the Romans came from a shameful act of treachery from which his countrymen suffered at the hands of one of the Roman generals. This man had expressed his pity for the poverty of their country, which drove them, he said, into robbing their neighbours. He would give them, if they would trust him, lands better worth cultivating. What he did was to massacre them in detachments, one detachment being kept in ignorance of the fate of those who had gone before. Viriathus was one of the few who escaped. It was not for some time that he secured the complete confidence of his countrymen, or was able to collect an army with which he could meet his adversaries in the field. His first great success was won in 147 B.C., when the proprætor Vetilius was drawn into an ambush and defeated. Vetilius was taken prisoner and killed by his captors, who, seeing only a "very fat old man," did not recognise his value. Two-fifths of the army of ten thousand perished at the same time. Another disaster happened in the year following. Plautius, the Roman general, was deceived by a pretended retreat, and suffered a heavy loss of men. Affairs seemed to be in so serious a condition that the authorities at Rome resolved on sending a large force and as able a commander as they could find to the seat of war. The man they chose was Fabius, the brother of the younger Scipio, and a son therefore of the famous conqueror of Macedonia.[35] Before Fabius could reach the scene of war another Roman army had been almost destroyed. Fabius himself for a time could do but little. He had to content himself with getting his forces, all of them newly recruited, into order. In his second year of command, however, he inflicted a severe defeat on Viriathus and compelled him to evacuate the Roman territory.
