Napoleon Bonaparte was a military genius. He took France to glory as the nation dominated Europe under him.
However, Battle of Waterloo was Napoleon’s decisive defeat. The genius strategist made a few errors.
To start with, Napoleon left his best general Louis-Nicolas Davout in Paris.
Napoleon waited for hours before attack. This gave Prussian army time to join the British.
Napoleon made Michel Ney in-charge of cavalry. Ney made costly mistake of charging at the British without artillery support.
Imperial Guard consisted of Napoleon’s elite soldiers. But he ordered them to attack where the British were strongest.
