 The chase continued into the dark and squally night, leading it to later become known as the "Moonlight Battle", since it was uncommon at the time for naval battles to continue after sunset. At 7: 30 pm, HMS Defence came upon Lángara's flagship Fenix, engaging her in a battle lasting over an hour. She was broadsided in passing by HMS Montagu and HMS Prince George, and Lángara was wounded in the battle. Fenix finally surrendered to HMS Bienfaisant, which arrived late in the battle and shot away her mainmast. Fenix's takeover was complicated by an outbreak of smallpox aboard Bienfaisant. Captain John MacBride, rather than sending over a possibly infected prize crew, apprised Lángara of the situation and put him and his crew on parole.
