The difference between a filibuster and a freebooter is one of ends rather than of means. Some authorities say that the words have a common etymology; but others, including Charlevoix, maintain that the filibuster derived his name from his original occupation, that of a cruiser in a "flibote," or "Vly-boat," first used on the river Vly, in Holland. Yet another writer says that the name was first given to the gallant followers of Dominique de Gourgues, who sailed from Finisterre, or Finibuster, in France, on the famous expedition against Fort Caroline in 1567.
