The Roman general, pretending that it might be possible to arrange terms of peace, sent ambassadors, during a short truce, to the camp of Syphax. But his true reason for doing so was that they might find out something of the numbers of the enemy and of the position of its camp.
As was therefore to be expected, the negotiations were of no use, and were soon broken off.
The Punic army believed that the attack on Utica would at once be renewed. It did not dream that its camp was in danger.
But Masinissa knew that the camp was guarded carelessly. He also knew that the tents in the camp were huts, built of wood, and covered with branches of trees or with rushes. So he advised Scipio to plan a night attack on the camp, and to set fire to the huts.
One night Scipio resolved to do as Masinissa had suggested. He ordered his men to have supper early. The bugles sounded at the hour usual for the evening meal, that the enemy’s attention might not be attracted by any departure from the daily routine. But on this night the bugle was not the signal for supper, but the call to march.
It was cold and dark when, soon after midnight, the whole Roman army drew near to the camp of the Carthaginians, having marched a distance of seven miles.
Masinissa at once ordered every exit to be closely guarded, then he stealthily set fire to the huts on the edge of the camp.
The flames spread rapidly from one wooden hut to another until, before the Carthaginians were aware, their whole camp was in a blaze.
Late as it was, some of the officers were still feasting when the smoke and the noise of crackling wood roused them to a sense of danger.
They rushed out, still carrying in their hands the cups out of which they had been drinking, to see the tents blazing fiercely.
