Episode 34, "Fortress vs. Fortress Akt I: Cannon Fire"
Synopsis: Iserlohn and Geiersburg exchange main weapon fire, damaging both fortresses. In charge until Yang returns, Caselnes wants to concentrate on purely defensive measures. The fighter craft are sent out and engage in space dogfights, but it appears to be a feint so that Mueller can circle around Iserlohn and deploy explosive charges that damage Iserlohn's gun batteries. Empire troops penetrate Iserlohn in landing crafts, only to meet the Rosen Ritter.
