Pompey (19.3-19.4)

Then, when more foes rushed upon him together, his troops being now routed, he made his escape, contrary to all expectation, by abandoning to the enemy his horse, which had golden head-gear and ornamented trappings of great value. They fought with one another over the division of these spoils, and so were left behind in the pursuit.[*]

At break of day, however, both generals drew up their forces again to make the victory assured, but on the approach of Metellus, Sertorius retired and his army dispersed. His men were accustomed to scatter in this way, and then to come together again, so that often Sertorius wandered about alone, and often took the field again with an army of a hundred and fifty thousand men, like a winter torrent suddenly swollen.
