 A search soon found that the Spanish had left a slow-burning fuse leading to the fort's powder kegs as a trap for the buccaneers, which Morgan extinguished.The fort's guns were spiked and then buried so they could not be used against the privateers when they returned from the rest of their mission.Morgan arrived at Maracaibo to find the city largely deserted, its residents having been forewarned of his approach by the fortress's troops.
