During the Grand Dérangement, approximately 3,000 Acadians were sent to France. Most of them were from île Saint-Jean, peninsular Nova Scotia and île Royale and settled in Poitou and in Brittany, in such places as Archigny, Châtellerault and Belle-Île-en-Mer. Having problems adapting to their new homeland, hundreds of deportees decided to leave for Louisiana or Saint-Pierre et Miquelon. Some were relocated to different French colonies of Central America, but these colonization attempts in the West Indies and Guiana were disastrous: the climate and the unsanitary conditions claimed many lives and those who survived returned to France or made it to Louisiana. France also tried to settle the Acadians in the Falkland Islands, close to Argentina. Some of them dispersed in South America or returned to France, but the majority did remain on the island. The Acadians who were deported the most often were those who went to another French colony, Saint-Pierre et Miquelon. They were moved no less than four times. The Acadians who returned to the islands in 1816 were the last migrants of the Deportation which had taken place more 60 years before.
