Guerra do Brasil - Toda Verdade Sobre a Guerra do (1987)

Between 1864 and 1870, South America was the scene of the biggest and bloodiest armed conflict of the century, known as the "Paraguay War," or "Big War," for Paraguayans. Mixing reality and fiction, the documentary discusses this "draft" of World War I, which involved Brazil, Argentina, Uruguay and Paraguay, decimating around one million people.
