Short answers, pulled from the story.
Napoleon celebrated at least 75 victories and suffered 11 defeats across a military career spanning more than 20 years. Seven additional battles ended with an uncertain or inconclusive outcome. Most of his defeats came toward the end of his career, when the French army was no longer at its peak.
Napoleon was defeated at Waterloo in 1815 during the Hundred Days campaign. He spent his remaining days in British custody on the remote volcanic tropical island of Saint Helena. His final defeat followed an earlier exile to the island of Elba after his defeat in 1814.
Napoleon's most celebrated victories included Toulon, Rivoli, Austerlitz, Friedland, and Dresden. Austerlitz ended the War of the Third Coalition, while Friedland ended the War of the Fourth Coalition. Military schools worldwide have studied these battles as examples of strategic and tactical genius.
The Six Days' Campaign was a rapid offensive in which Napoleon faced an enemy army that outnumbered him by more than two to one. Striking at Champaubert, Montmirail, Chateau-Thierry, and Vauchamps in quick succession, his forces caused the enemy army to lose more than half its total strength. The battle of Vauchamps was particularly noted for its exceptional ratio of forces to casualties.
The French dominion collapsed rapidly after the invasion of Russia in 1812. Napoleon was defeated in 1814 and initially exiled to the island of Elba before returning to France. His final defeat came at Waterloo in 1815.
Napoleon deliberately weakened his own right flank to lure the Allied forces down from their defensive position on the heights. When the Allies advanced to exploit the apparent weakness, Napoleon delivered a concentrated blow to the now-undefended high ground, drove his forces upward, and cut the Allied army in two. The Allied casualties were catastrophic, and the victory ended the War of the Third Coalition.
