S1·E5 The Castrop Uprising

A new admiralty is created for Reinhard. He chooses commoners and lesser nobles to command his fleets: August Samuel Wahlen, Cornelius Lutz, Karl Gustav Kempf, Fritz Josef Bittenfeld, Ernest Mecklinger, Wolfgang Mittermeyer and Oskar von Reuenthal. Meanwhile, Maximilian von Kastrop has rebelled against the Empire. He thinks he is safe because of the "Artemis Necklace", a system of powerfully armed satellites built with the help of Phezzan. Reinhard sends a fleet under Kircheis' command to put an end to the rebellion. He manages to destroy the necklace. Kastrop is killed by his retainers and is the only casualty of the operation.
