Nevertheless, on those occasions during the Second Punic War when they were deployed properly, led competently, and/or had the advantage of numbers or surprise, such as during the skirmish before Ilipa and at the pitched battles of the Great Plains and Zama, the Roman cavalry were able to best their Carthaginian counterparts, independent of the success of their own allied Numidians. On occasion, such as at Dertosa, they were able to hold their own despite being supposedly outnumbered in a skirmish with Carthaginian cavalry.
