French frigates operating from Brest were conducting commerce-raiding cruises in the Western Approaches, damaging British trade. Royal Navy frigate squadrons regularly patrolled from Cork to counter these raiders. Despite British dominance in the Western Atlantic, French short-cruise raiders posed a persistent threat to merchant shipping.
A British frigate patrol encountered a French squadron of two frigates and a corvette near the Scilly Isles on 22 June 1796. A day-long chase ended with HMS Santa Margarita capturing Tamise and HMS Unicorn defeating Tribune. Five days later HMS Dryad captured the frigate Proserpine off Cape Clear, and nine days after that Légère was taken without resistance by another British patrol.
All four captured French vessels were purchased into Royal Navy service. French casualties across the three engagements were described as very heavy, while British losses remained light. The campaign effectively dismantled the French frigate squadron that had been preying on British commerce in the Western Approaches.
