Spain 15 galleys The action of 3 October 1624 was a naval engagement that took place near San Pietro Island, Sardinia, during the war against the Barbary corsairs.

In Cagliari, Pimentel consulted with Juan Vives de Canyamás, viceroy of Sardinia, if he had information about the Barbary corsairs, but he knew nothing.

[6] The battle began, and after four hours of fighting, the Christians captured one of the large ships after it was disabled and abandoned by the crew, who moved to the flagship.

Soon another of the large ships was also captured, but Algiers' flagship held up fierce resistance, causing extensive damage to the approaching galleys.

On the other hand, the pataches began to flee, so Pimentel ordered Francisco Manrique to pursue them with eight galleys.

The corsairs set fire to the gunpowder, causing a large explosion that destroyed the flagship after eight hours of fighting.

[8] The two large ships and the two pataches were escorted by the galleys to Cagliari, their salvage bringing a good quantity of ducats.
