11. It happened about the same time, that Laelius and Masinissa having arrived in Numidia after a march of about fifteen days, the Massylians, Masinissa's hereditary kingdom, placed themselves under the protection of their king with the greatest joy, as they had long wished him among them. After the commanders and garrisons of Syphax had been expelled from thence, that prince kept himself within the limits of his original dominions, but without any intention of remaining quiet. Subdued by the power of love, he was spurred on by his wife and father-in-law; and he possessed such an abundance of men and horses, that a review of the resources of his kingdom, which had flourished for so many years, was calculated to infuse spirit into a mind even less barbarous and impetuous than his. Wherefore, collecting together all who were fit for service, he distributed among them horses, armour, and weapons. He divided his horsemen into troops, and his infantry into cohorts, as he had formerly learnt from the Roman centurions. With an army not less than that which he had before, but almost entirely raw and undisciplined, he set out to meet the enemy, and pitched his camp at a short distance from them. At first a few horsemen advanced cautiously from the outposts to reconnoitre, and being compelled to retire, from a discharge of javelins, they ran back to their friends. Then skirmishing parties were sent out from both sides, and the vanquished, fired with indignation, returned to the encounter with increased numbers. This is the usual incitement of battles between cavalry, when the victors are joined by more of their party from hope, and the vanquished from resentment. Thus, on the present occasion, the action commencing with a few, at last the whole body of the cavalry on both sides poured out to join in it from the zeal excited by the contest. While the cavalry only were engaged, it was scarcely possible to withstand the numbers of the Masaesylians, which Syphax sent out in immense bodies. But afterwards, when the Roman infantry, suddenly coming up between the troops of horse which made way for them, gave stability to their line, and checked the enemy, who were charging furiously, at first the barbarians slackened their speed, then halted, and were in a manner confounded at this novel kind of battle. At length, they not only retired before the infantry, but were unable to sustain the shock even of the cavalry, who had assumed courage from the support of the infantry. By this time the legions also were approaching; when, indeed, the Masaesylians not only dared not await their first charge, but could not bear even the sight of the standards and arms; so powerful was either the recollection of their former defeats, or their present fears.
