Napoleon's enemies were quick to take advantage of France's Weakness, all his major enemies were against him. Napoleon's personality proved to be the greatest danger for his future. His drive for power raised him, and his love for power led to his doom. Within a few months, he had constructed a new army that was inexperienced. His empire quickly crumbled, and when he wanted to fight, his generals refused. He surrendered, and was sent to an island, Elba, off the coast of Italy, and found it hard to retire at age 45. Almost immediately, there was opposition to the new ruler, citizens feared he would undo changes from the revolution. Napoleon escaped, and gathered an Army of loyalists, who then regained the throne in a matter of days. At the battle of Waterloo, Napoleon and his troops held the British until the Prussian army came, and they sent the French troops running. That ended his 100 days of rule. Then he was sent to a remote island, St. Helena, where he spent 6 years in exile. Napoleon was a military genius, but his success must be measured by the amount of lives lost.
