December 2, 1805Battle of Austerlitz
The Battle of Austerlitz, also known as the Battle of the Three Emperors, was one of Napoleon's greatest victories, where the French Empire effectively crushed the Third Coalition. On 2 December 1805, a French army, commanded by Emperor Napoleon I, decisively defeated a Russo-Austrian army, commanded by Tsar Alexander I and Francis II of Holy Roman Empire, after nearly nine hours of difficult fighting. The battle took place near Austerlitz (Slavkov u Brna) about 10 km (6.2 mi) south-east of Brno in Moravia, at that time in the Austrian Empire (present day Czech Republic). The battle is often regarded as a tactical masterpiece.
