While the struggle was thus continued at Zama, Jugurtha, at the head of a large force, suddenly attacked the camp of the Romans, and, through the remissness of those left to guard it, who expected any thing rather than an attack, effected an entrance at one of the gates. Our men, struck with sudden consternation, acted each on his own impulse; some fled, others seized their arms; and many of them were wounded or slain. About forty, however, out of the whole number, mindful of the honor of Rome, formed themselves into a body, and took possession of a slight eminence, from which they could not be dislodged by the utmost efforts of the enemy, but hurled back the darts discharged at them, and, as they were few against many, not without execution. If the Numidians came near them, they displayed their courage, and slaughtered, repulsed, and dispersed them, with the greatest fury. Metellus, meanwhile, who was vigorously pursuing the siege, heard a noise, as of enemies, in his rear, and, turning round his horse, perceived a party of soldiers in flight toward him; a certain proof that they were his own men. He instantly, therefore, dispatched the whole of the cavalry to the camp, and immediately after-ward Caius Marius, with the cohorts of the allies, entreating him with tears, by their mutual friendship, and by his regard for the public welfare, to allow no stain to rest on a victorious army, and not to let the enemy escape with impunity. Marius soon executed his orders. Jugurtha, in consequence, after being embarrassed in the intrenchments of the camp, while some of his men threw themselves over the ramparts, and others, in their haste, obstructed each other at the gates, fled, with considerable loss, to his strongholds, Metellus, not succeeding in his attempt on the town, retired with his forces, at the approach of night, into his camp.
