The Silver-White Valley: Chapter III - S1.E3

Reinhard von Müsel and Siegfried Kircheis successfully ambush a Free Planets Alliance tank advance unit and secure not only fuel, but also information about an upcoming Alliance surprise attack on their base. Suspecting that their base commandant Captain Herder was responsible for their predicament, they decide to wait for any of his accomplices to appear. Eventually, Lieutenant Hugenberch finds them and after he shows hostile intent, Reinhard kills him. They then return to their base and finds the surprise attack already started. Kircheis manages to disable the attacking Alliance tanks by transmitting to them a code he wrote based on stolen data from the tanks he and Reinhard previously ambushed, enabling the Imperial forces at their base to successfully counter-attack and end the Alliance surprise attack.
