He came back to France, was hailed as Emperor again, and then they had to fight the Battle of Waterloo to defeat him for the final time.
After that, he was exiled to a far more desolate place - St. Helena.
The island has a history of over 500 years since it was first discovered as an uninhabited island by the Portuguese in 1502. Claiming to be Britain’s second oldest colony, this is one of the most isolated islands in the world and was for several centuries of vital strategic importance to ships sailing to Europe from Asia and South Africa. For several centuries the British have used the island as a place of exile, most notably for Napoleon Bonaparte, Dinuzulu kaCetshwayo and over 5,000 Boer prisoners.

Isolation
Saint Helena is one of the most isolated places in the world, located more than 2000 km (1200 mi) from the nearest major landmass. As there is currently no airport on Saint Helena, travel to the island is by ship only. The RMS Saint Helena berths in James Bay approximately thirty times per year. The ship calls on such other ports as Cape Town, Ascension Island, Tenerife, Vigo, Walvis Bay and Isle of Portland, UK. <2>
http://en.wikipedia.org/wiki/Saint_HelenaOr, for somewhere even more isolated, the dependency of Tristan da Cunha:
Tristan da Cunha (pronounced /ˈtrɪstən də ˈkuːnə/) is a group of remote volcanic islands in the south Atlantic Ocean, 2,816 km (1,750 miles) from South Africa and 3,360 km (2,088 miles) from South America. It is a dependency of the British overseas territory of Saint Helena, 2,430 km (1,510 miles) to the north. The territory consists of the main island, Tristan da Cunha (area: 98 km², 38 sq mi ), as well as several uninhabited islands: Inaccessible Island and the Nightingale Islands. Gough Island (area: 91 km², 35 sq mi ), situated 395 km (245 mi) south east of the main island, is also considered part of the territory. Tristan da Cunha is the most remote archipelago in the world.

The remote location of the islands makes transport to the outside world difficult. There is no airport, so the islands can only be reached by boat. Fishing boats from South Africa regularly service the islands. The RMS Saint Helena formerly connected the islands to South Africa, and the United Kingdom via Saint Helena and Ascension Island, but she no longer calls at Tristan da Cunha.
