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.
