Battle of Formentera

Habsburg emperor Charles V had sent a small Spanish fleet of eight galleys under the Spanish commander of the Castilla fleet, Rodrigo Portuondo, to eliminate Barbary ships from Algiers under Caccia Diavolo which were raiding the coast of Valencia and ferrying Moriscos from Spain to Algeria.

Portuondo was killed in the battle, seven of his eight galleys were captured, and his soldiers were taken as slaves to the recently conquered city of Algiers, and 1000 Muslim galley slaves had been liberated.
