The Spanish fleet reached
Isla Barú on the evening of 7 June and anchored there. On the next day there was very little wind, and around 3 p.m. they noticed Wager's squadron approaching. The Spanish took up defensive positions, but the British knew they had to attack the largest ships, because they had the most money on board. The
Kingston attacked the
San Joaquín around 5 p.m. which, after two hours of battle, escaped into the night with the help of the
Concepción. The
Expedition attacked the
San José and approached the vessel with the clear intention of
boarding the ship. Around 7 p.m., after an hour and a half of fierce fighting and with only 60 meters between the two ships, the
San José suddenly blew up. The ship sank immediately, taking its precious cargo and almost the entire crew to the bottom of the sea. There were only 11 survivors out of the 600 crew and passengers on board; José Fernández de Santillán went down with his ship. By now it was dark, but there was a full moon and Wager succeeded in finding the
Santa Cruz at 2 a.m. After a brief fight, which left 14 British and 90 Spanish dead, the
Santa Cruz was taken; however, she had no government treasure in her - only 13 chests of
pieces of eight and 14
pigs of silver which seem to have been private property. At dawn, the British discovered the
San Joaquín, and Wager ordered the
Kingston and
Portland to capture the ship. After a few salvos, however, the
San Joaquín successfully made way towards Cartagena harbour, and the British decided against following them. The rest of the Spanish fleet also reached Cartagena safely, except the hulk
Concepción which, cornered by the British, beached itself on Baru Island where the crew set the ship alight. ==Aftermath==
