La Débâcle is a novel by Émile Zola published in 1892, the penultimate in les Rougon-Macquart series. The story is set against the background of the political and military events that ended the reign of Napoléon III and the Second Empire in 1870, in particular the Franco-Prussian War, the Battle of Sedan and the Paris Commune.

In "The Downfall" Zola tells the story of a terrific land-slide which overwhelmed the French Second Empire: It is a story of war, grim and terrible; of a struggle to the death between two great nations. In it the author has put much of his finest work, and the result is one of the masterpieces of literature. The hero is Jean Macquart, son of Antoine Macquart and brother of Gervaise. After the terrible death of his wife, as told in "La Terre" ("The Soil"), Jean enlisted for the second time in the army, and went through the campaign up to the battle of Sedan. After the capitulation he was made prisoner, and in escaping was wounded. When he returned to active service he took part in crushing the excesses of the Commune in Paris... The Downfall has been described as "a prose epic of modern war," and vast though the subject be, it is treated in a manner that is powerful, painful, and pathetic.

The Downfall by Zola belongs to the most outstanding masterpieces of the world's literature. Zola tells about a terrific land-slide that overwhelmed the French Second Empire in this work. The story's main character is Jean Macquart, a French soldier who loses a lot during a war and comes through the perils of the bloodiest battles just to get into another war. It is a critical political work describing the nonsense and cruelty of armed conflicts.
