So long as we are discussing multi-lingual environments:
I just finished J Sancton's "Madhouse at the End of the Earth" (Crown, 2021), the first English-language book about the Belgica expedition to Antartica (1897-1899) under the command of the Belgian commandant Adrien de Gerlache with Belgian backing and a polyglot crew. The lingua franca aboard ship became a "mixture of French, Dutch, Norwegian, German, Polish, English, Romanian, and Latin" (p 5). Among the ship's company were F Cook and R Amundsen, who became infamous and famous explorers on their own expeditions.
