On 1 May 1669 Morgan and his flotilla attacked the Spanish squadron. The fire ship plan worked, and "Magdalen" was shortly aflame; Espinosa abandoned his flagship and made his way to the fort, where he continued to direct events. The second-largest Spanish ship, "Soledad", tried to move away from the burning vessel, but a problem with the rigging meant they drifted aimlessly; privateers boarded the ship, fixed the rigging and claimed the craft as plunder. The third Spanish vessel was also sunk by the privateers. Morgan still needed to pass the San Carlos de la Barra Fortress, but was still out-gunned by the stronghold, which had the ability to destroy the privateer fleet if it tried to pass. The privateer decided to negotiate, and threatened to sack and burn Maracaibo if he was not allowed to pass. Although Espinosa refused to negotiate, the citizens of Maracaibo entered into talks with Morgan, and agreed to pay him 20,000 pesos and 500 head of cattle if he agreed to leave the city intact. During the course of the negotiations with the Maracaibos, Morgan had undertaken salvage operations on "Magdalen", and secured 15,000 pesos from the wreck. Before taking any action, Morgan tallied his takings and divided it equally between his ships, to ensure that it was not all lost if one ship was sunk; it totalled 250,000 pesos, and a huge quantity of merchandise and a number of local slaves.
