Researching Marquis Rays

Charles was born on the family estate Quimerc'h in Brittany, the son of Charles du Breil and Mari Prevost. As a child in 1838 he succeeded his father as marquis and spent his youth in fortune-seeking but ineffective adventures abroad: in the United States, Senegal, Madagascar, and Indo-China. He eventually returned to France, where, on 22 September 1869, he married Emilie Labat, who gave him five children, including one known son: Eugène Paul Emile.

It was the defeat of France in the Franco-Prussian War and the readings he made of some navigators' journals that prompted de Rays to embark on further adventures for the glorification of France and the Roman Catholic Church. The theatre for his ambitions was to be the South Pacific, where in 1877 he was self-proclaimed "Charles, King of New France" (La Nouvelle France), an imaginary Oceanic empire covering territories as yet unclaimed by any European powers. Through advertisements, word of mouth, and a journal of his own publishing, Nouvelle France, de Rays brought to public attention his plans for converting and then colonising the South Pacific, which he claimed abounded in fertile soil. Specifically, de Rays planned to start a colony, "Colonie Libre de Port Breton", at Port Praslin. His ideas were universally rejected by governments, but enough people believed his wild predictions to support an expedition.

The third of his expeditions, often referred to simply as the de Rays Expedition, in 1880 is most famous for its absolute failure. Aboard the ships Chandernagore, Gentil, Nouvelle Bretagne, and India, a motley group of 570 ill-prepared colonists, in the main French, German, and Italian, arrived at Port Breton. The marquis is widely believed to have deliberately misled the colonists, distributing literature claiming a bustling settlement that did not exist, near present-day Kavieng, which had numerous public buildings, wide roads, and rich, arable land. This port was further purported to be capital of a great empire, his "Kingdom of New France". In fact, the site was an extremely poor choice: supplies were difficult to get through and malaria was unavoidable. The high death rate convinced most colonists to soon flee to Australia, New Caledonia, and the Philippines.

De Rays himself did not visit his colony and was arrested for fraud in Spain in July 1882. He was extradited to France and sentenced to six years in prison for criminal negligence, but his career as an adventurer was not over. He died in a French asylum near Rosporden after accruing several more failures to his name.
