Between 1817 and 1825, 10,000 British mercenaries, many of them veterans of the Napoleonic Wars, left Europe to join the armies and navies of Bolivar, San Martin, and other leaders fighting to liberate their countries from the colonial domination of Spain and Portugal. Very few of these mercenaries came back. Many succumbed to tropical diseases or battles, and the remainder settled in the new states that they helped to create. This two-volume edition tells the little known story of these freedom mercenaries. Using historical evidence, this work offers a complete study of the struggle of both Britons and South Americans in these Wars of Independence and analyzes their actions in the larger context of the foreign policies of the United Kingdom, France, the United States, Imperial Russia, and the German States. Each volume features self-contained, but complementary chapters that follow one major unit or volunteer. Written in an approachable style, this book offers insight into an under-examined historical epic.
