George Anton Schaeffer Shipping Germans to Brazil by Lee B Croft

This the third book in a biographical trilogy of books about George Anton Schaeffer (1779-1836), a German physician who came to administer a secret project of Russian Tsar Alexander I to construct a shark-shaped, hydrogen-filled, rotor-wing-powered balloon from which to drop timed-fuse explosives on Napoleon Bonaparte and his soldiers who were invading Russia in the summer of 1812 (book one of the trilogy), participated in a Russian "reverse circumnavigation of the world" and was stranded in Alaska, from where the Governor of Russian America Alexander Baranov sent him on a mission to establish a provisioning outpost for the Russians' north Pacific fur enterprise in the Hawaiian islands where he meddled in inter island politics during the reign of Kamehameha and ruled the island of Kaua'i as co-regent with its last independent King, Kaumuali'i, in 1816-7 (book two of the trilogy), and wound up founding a colony called Frankenthal in the Bahia State of Brazil and transporting thousands of German mercenaries and colonists to Brazil on behalf of Brazil's first independent Emperor Dom Pedro I and his Hapsburg wife, Dona Leopoldina from 1821 to 1830 (this book in the trilogy).
