Events of Red Dead Redemption 2
Aguasdulces is first seen, when Dutch and Arthur sneak into the town, in search of Javier. They soon spot him being pulled by a donkey, and surrounded by Fussar and other soldiers. The pair quickly begin looking for a way to cause a distraction in order to rescue him, and find it in the grain refinery. After killing the guards in the refinery, Dutch cuts up the bags of sugar, and they blow up the furnace, causing extensive destruction. In the confusion, the pair run in and grab Javier, before running off. Arthur halts on the other side of the Arroya de la Vibira river. Arthur holds off the soldiers while Dutch carries Javier away, before following him.
After the Battle for Cinco Torres, Hercule, Micah, Dutch and Arthur attack Aguasdulces with the goal of rescuing the ship captain being held captive by Fussar. Arthur breaks into the workers' cabin and finds the captain, before being held at gunpoint by Levi Simon. Dutch runs into the room and holds Simon at gunpoint, only for Fussar to enter and aim his gun at Dutch. Dutch and Arthur also both pull out their guns, and aim them at Fussar. A mexican standoff ensues, until Arthur kicks his rifle to the ship captain, who kills Simon. Fussar then flees the cabin, and falls back to the port. The gang and Hercule then assault the port fortifications, and succeed in cutting through them, when they realize that Fussar is commanding the last cannon guarding the port. Arthur blows up the tower he is in, and the gang board the ships in Aguasdulces, departing the island.
