After leaving Denmark some months after the wake of the events of 1634: The Baltic War, Commander Eddie Cantrell of the USE Navy resumes his work under Admiral John Simpson, working on the USE's new fleet of ocean-going steam frigates and their breechloading rifled cannon. Simpson sends Cantrell to join an expedition to the Caribbean, which will take a variety of equipment and tools, and serve as a first test for the steam frigates. Their main objectives: link up with the survivors of the Dutch fleet defeated at the Battle of Dunkirk during the Ostend War, under the command of Maarten Tromp, and secure the easily tappable oil supplies at Pitch Lake on the island of Trinidad.
