Bazán hid the fleet near the Kerkennah Islands and order captain Diego Pimentel, the son of
Juan Alonso Pimentel de Herrera, to block the pass between the islands and the coast with six galleys. Pimental first and the rest of the fleet afterwards had to the scout the location given that they had no reliable knowledge of it. On 27, the fleet faced the island of
Chergui and performed an
amphibious assault against the towers and fortifications built by the Tunisians, employing the artillery to cover the landing. The infantry divided itself in three squads, captained by
maestre de campo Sancho de Luna and Luis de Córdoba, and took over the island, burning down all the buildings and sacking the local cattle. Shortly after they assaulted the bulwark in the island of
Gharbi, with the help of a local whom they freed in exchange for showing them the way. Bazán ordered the infantry to wade towards Gharbi on low tide and secure the place for the cavalry led by Antonio de Mendoza, but the plan collapsed when several noblemen in the cavalry, among them Giovanni d'Ávalos, descendant of
Fernando d'Ávalos, attacked before their time. The allied cavalry became swamped and suffered casualties while the infantry tried to assist them, until finally discipline returned and they managed to reform again. The allies finally overcame the local resistance, killing 380 defenders and forcing the rest to abandon the bulwark, killing 300 more and capturing 500 before the rest escaped in boats to mainland. Not finding any more enemies, Bazán gave the order to return to the galleys and return to Sicily. ==Aftermath==
