The Africans, lulled into security by proposals of peace suggested by Scipio with more artifice than honour, allowed themselves to be surprised on one and the same night in their two camps; the reed huts of the Numidians burst into flames, and, when the Carthaginians hastened to their help, their own camp shared the same fate; the fugitives were slain without resistance by the Roman divisions.

This nocturnal surprise was more destructive than many a battle; nevertheless the Carthaginians did not suffer their courage to sink, and they rejected even the advice of the timid, or rather of the judicious, to recall Mago and Hannibal.

Just at this time the expected Celtiberian and Macedonian auxiliaries arrived; it was resolved once more to try a pitched battle on the "Great Plains," five days' march from Utica.

Scipio hastened to accept it; with little difficulty his veterans and volunteers dispersed the hastily- collected host of Carthaginians and Numidians, and the Celtiberians, who could not reckon on any mercy from Scipio, were cut down after obstinate resistance.

After this double defeat the Africans could no longer keep the field.
