They sighted the Spanish 12-pounder 34-gun frigate Santa Catalina commanded by Don Miguel Tacón.

This ship was part of a squadron keeping lookout for any relief convoys heading into Gibraltar, which was then under siege.

When the Spanish frigate approached within random shot, the Success suddenly hauled up and poured a destructive broadside.

The Santa Catalina, having lost her mizzenmast at around 8:00 pm, hauled down her colours, and then was taken possession of by the Success.

[1] Pole, fearing the Spaniards had formed a plan to take possession of the Success and the Santa Catalina, decided that once all the valuables and prisoners had been removed, it was necessary to destroy her.
