Legend of the Galactic Heroes – S01 E22 : Courage and Allegiance

Littenheim leaves Geiesburg with his fleet to recover the territories conquered by Kircheis. Because of its lack of discipline and overconfidence of its commanders, the Littenheim Fleet is defeated; while running away, Littenheim's spaceship opens fire on allies who are in the way. In the Garmisch fortress, Littenheim is killed by his men, enraged by such an attitude. Meanwhile, Reinhard's fleet arrives in the area of Geiesburg. The Lippstadt Fleet attacks him but is utterly beaten and barely avoids complete destruction thanks to admiral Merkatz.
