1x21 - Legend of the Galactic Heroes

Schenkopp takes control of the rebel planets on behalf of the Yang fleet. The National Salvation Military Council sends commodore Bagdashu to Yang to pose as a traitor to the coup in order to kill him, but Schenkopp manages to take him away. Yang's 13th Fleet meets the 11th Fleet in the Doria star system; the 11th Fleet is destroyed because its commanders turn down Yang's proposal of surrender. After the battle, Bagdashu decides to join Yang because his victory is certain. Meanwhile, in Heinessen, a peaceful gathering against the coup is held in a stadium. When the army tries to scatter it, it turns into a riot, and thousands are killed, including Jessica Edwards.
