A few months later, however, the tribe of the Leuathae, in Tripolitania, rose up, and inflicted a severe defeat upon the imperial forces in the plain of Gallica. The Leuathae were joined by Antalas, and the Moors once again raided freely as far as Carthage. Early in the next year John mustered his forces, and together by several allied Moorish tribes, including the former rebel Cutzinas, utterly defeated the Moors at the battle of the Fields of Cato, killing seventeen of their leaders and putting an end to the revolt that had plagued Africa for almost 15 years.
