Once the convoy was formed, they left Cartagena port, given the lack of wind. The Spanish fleet arrived at
Cape Palos on August 4 and encountered a group of 16 Algerian ships led by
Sulayman Reis and Mustapha Reis. The various versions known of the battle suggest that the battle began with a first attack by the Spanish flagship, where the commander of the expedition, Lázaro de Eguiguren, however, the other vessels hesitated to join the battle. A fierce battle ensued, and the Spanish put up a fierce fight but were overwhelmed in the end. Lázaro de Eguiguren managed to regroup the other vessels and retreat to Cartagena. The Spanish have lost two ships in this battle, the
Neptuno and
El perro del Agua, alongside 715 killed or captured. Many of those wounded in battle died when arriving, reducing the number of survivors to 700 men. ==Aftermath==
