The whaling ship Catalpa set out from New Bedford, Massachusetts, on the morning of April 29, 1875, to undertake a daring yearlong mission of international rescue. American captain George Anthony risked his career as a whaler—and his life—to rescue a group of British-soldiers-turned-Irish-rebels known as “The Fremantle Six” from their prison in Australia. With the help of the prison chaplain, the six men escaped to the coast where Anthony was waiting with a small whaleboat that would take them to the Catalpa. The resistance they overcame, both from armed British vessels and a furious sea storm, made their escape the stuff of legend. In what Britain considered a near act of war, the Catalpa outran the Royal Navy and deposited its politically dangerous cargo in New York Harbor in August 1876.
