Nevertheless the besieged frequently offered battle; but Scipio, perceiving clearly that the disorganization of many years was not to be repaired all at once, refused to accept it, and, when conflicts did occur in connection with the sallies of the besieged, the cowardly flight of the legionaries, checked with difficulty by the appearance of the general in person, justified such tactics only too forcibly. Never did a general treat his soldiers more contemptuously than Scipio treated the Numantine army; and he showed his opinion of it not only by bitter speeches, but above all by his course of action. For the first time the Romans waged war by means of mattock and spade, where it depended on themselves alone whether they should use the sword. Around the whole circuit of the city wall, which was nearly three miles in length, there was constructed a double line of circumvallation of twice that extent, provided with walls, towers, and ditches; and the river Douro, by which at first some supplies had reached the besieged through the efforts of bold boatmen and divers, was at length closed. Thus the town, which they did not venture to assault, could not well fail to be reduced through famine; the more so, as it had not been possible for the citizens to lay in provisions during the last summer. The Numantines soon suffered from want of everything. One of their boldest men, Retogenes, cut his way with a few companions through the lines of the enemy, and his touching entreaty that kinsmen should not be allowed to perish without help produced a great effect in Lutia at least, one of the towns of the Arevacae. But before the citizens of Lutia had come to a decision, Scipio, having received information from the partisans of Rome in the town, appeared with a superior force before its walls, and compelled the authorities to deliver up to him the leaders of the movement, 400 of the flower of the youth, whose hands were all cut off by order of the Roman general. The Numantines, thus deprived of their last hope, sent to Scipio to negotiate as to their submission and called on the brave man to spare the brave; but when the envoys on their return announced that Scipio required unconditional surrender, they were torn in pieces by the furious multitude, and a fresh term elapsed before famine and pestilence had completed their work. At length a second message was sent to the Roman headquarters, that the town was now ready to submit at discretion. When the citizens were accordingly instructed to appear on the following day before the gates, they asked for some days delay, to allow those of their number who had determined not to survive the loss of liberty time to die. It was granted, and not a few took advantage of it. At last the miserable remnant appeared before the gates. Scipio chose fifty of the most eminent to form part of his triumphal procession; the rest were sold into slavery, the city was levelled with the ground, and
