One reason for the extinction of the language was movement of the population. In particular, the influx of labourers from the United Kingdom employed by the British government in the construction of the abortive harbour project and other fortifications (during the reign of Queen Victoria), as well as the stationing of a sizable British garrison among the small population, served to relegate Auregnais to a lesser status for communication. The evacuation of nearly all indigenous Auregnais to the British mainland during World War II (the island was occupied by the Wehrmacht) was thought to be a major factor in the final loss of the spoken language.
