Kameradschaft (English: Comradeship, known in France as La Tragédie de la mine) is a 1931 dramatic film directed by Austrian director G. W. Pabst. The French-German co-production drama is noted for combining expressionism and realism.The film concerns a mine disaster where German miners rescue French miners from an underground fire and explosion. The story takes place in the Lorraine–Saar regions, along the border between France and Germany. It is based on one of the worst industrial accidents in history, the Courrières mine disaster in 1906 in Courrières, France, where rescue efforts after a coal dust explosion were hampered by the lack of trained mine rescuers. Expert teams from Paris and miners from the Westphalia region of Germany came to the assistance of the French miners. There were 1,099 fatalities, including children.Kameradschaft in German means a bond between soldiers or those who have similar opinions and are in friendship. The word is similar to comradeship, camaraderie or fellowship.
