The Spanish soldier Bernal Díaz del Castillo (ca. 1496-ca. 1584) was a member of the expedition that conquered the Aztec empire. His "A True History of the Conquest of New Spain" is the most complete contemporary chronicle of that event.
No figure of the Indian wars in America so typifies that era as George Armstrong Custer (1839-1876).He is known universally for the massacre that bears his name and for the blundering that brought it about.
