Masinissa, hearing of the death of his uncle, and afterwards that his cousin-german was slain, passed over out of Spain into Mauritania.
Bocchar was king of the Moors at that time.

Applying to him as a suppliant, he succeeded, by means of the most humble entreaties, in obtaining from him four thousand Moors to escort him on his march, since he could not procure his co-operation in the war.

With these, after sending a messenger before him to his own and his father's friends, he arrived on the frontiers of the kingdom, when about five hundred Numidians came to join him.

Having, therefore, sent back the Moors to their king, as had been agreed, though the numbers which joined him were much less than he had anticipated, not being such as to inspire him with sufficient confidence for so great an attempt, yet, concluding that by action, and by making some effort, he should collect sufficient strength to enable him to effect something, he threw himself in the way of the young king Lacumaces, at Thapsus, as he was going to Syphax.

The troops which attended him having fled back to the town in consternation, Masinissa took it at the first assault.
Of the royal party, some who surrendered themselves he received, others he slew while attempting resistance.
