Last days

In 1815, he escaped from Elba and actually gained the support of the soldiers that were sent to recapture him. His old supporters returned to his side as he resumed rule in Paris for what is known as the "100 Days." He sought peace with the Allies, but when they proclaimed him an outlaw, he went for the preemptive strike. He was swiftly defeated at the battle of Waterloo on June 8, 1815. He was exiled to the remote south-Atlantic island of St. Helena. He wrote his memoirs between numerous escape attempts. 

He grew very sick in his last days and died on May 5, 1821. Stomach cancer was first believed to be the cause of his death, though there has been much speculation of poisoning and medical malpractice.
