Sent to exile there as a condition of the Treaty of Fontainebleau — he was allowed to keep his title of “Emperor” and was the ruler of Elba, which was carved out as a separate principality, which means treaty-making was a different animal in 1815 and deposed dictators were treated a lot better than they are now — Napoleon was unhappy being separated from his wife and son (who were sent to Austria) and was not receiving the allowance he was guaranteed by the treaty (seriously, all those dictators who got hanged by their toes must look at Napoleon-on-Elba and just shake their heads). Further, he had heard rumors he was going to be sent to a remote island in the Atlantic (which, of course, he was, eventually).
Thus, he stole away while the guard ships were away, wisely timing his escape so he’d land in France as prisoners of the Napoleonic War were returning from their captors’ countries, thus providing him with an ever-growing army. And thus began the Hundred Days.
