Yang decides to take Iserlohn by a ruse. The Rosen Ritter (Knights of the rose), a ground combat unit made of Imperial exiles, will pose as an imperial crew and infiltrate the fortress. Yang's staff is introduced: Murai, Patrichev, Fischer (a master of fleet maneuvers) and Frederica Greenhill, daughter of admiral Dwight Greenhill. The Iserlohn fleet is lured away from the fortress by decoys. When a damaged imperial spaceship asks for help, the commander of Iserlohn, who doesn't know where his fleet is due to radar jamming, authorizes it to dock...

May, 14, 796 S.C. / 487 I.C.: a fake imperial spaceship docks into Iserlohn. Walter von Schenkopp, commander of the Rosen Ritter, pretends to have important information and takes control of the center of command. The Iserlohn fleet comes back, only to be destroyed by the fortress' main weapon, the "Thor's Hammer". The fall of Iserlohn dramatically changes the strategic balance: Yang hopes it will lead to a peace treaty. Back in Heinessen, he wants to resign, but is promoted to vice-admiral instead.
