Tamango

Captain Reiker (Curd Jürgens), a Dutch sea captain, sets off on what he intends to be his last slave-ship voyage. After capturing slaves with the complicity of an African chief (Habib Benglia), he then starts his voyage for Cuba. Along with the slaves below-deck, the passengers include his mistress, the slave Aiché (Dorothy Dandridge), and the ship's doctor, Doctor Corot (Jean Servais). Tamango (Alex Cressan), one of the captured men, plans a revolt and tries to persuade Aiché to join him and the other slaves. 

When the captured slaves do rebel, Tamango manages to hold Aiché hostage. A deadlock between the two sides then develops and Captain Renker states he will fire a cannon into the ship’s hold and kill all the slaves unless they give up. Aiché is given a chance to leave by Tamango but after looking up the ladder that leads out of the hold (and towards life), chooses to stay with her fellow slaves. The captain makes good on his threat and shoots the cannon into the hold, literally silencing the slaves' songs.
