Sedan, Battle of

(Sept. 1, 1870) Defeat of the French army in the Franco-Prussian War that led to the fall of the Second Empire. At the French border fortress of Sedan on the Meuse River, 120,000 French troops under Maurice, count de Mac-Mahon, were attacked by more than 200,000 German troops under Helmuth von Moltke. After Mac-Mahon was wounded, the confused French command tried unsuccessfully to break through the encircling German lines with massive cavalry charges. Emperor Napoleon III, who had accompanied Mac-Mahon, realized the French position was hopeless and surrendered with 83,000 troops.
