Captain Alonso Pinzon arrives in Hispaniola in 1530, in time to see ships calling there homeward bound from Mexico laden with fantastic treasure. He learns of an even richer land, an Eldorado, far to the south on the shores of the newly discovered Pacific Ocean. Disgusted with the brutal treatment of the local Indians in the islands by the Spaniards he decides to join the expedition led by Francisco Pizarro. Crossing the Isthmus of Panama, he assumes command of the Vencedor and, with two other caravels laden with men, horses, and materiel, sails in convoy to the south. On arrival in Tawantinsuyo, he marches with the expedition through the coastal desert and across the soaring ramparts of the Andes to Cajamarca where he witnesses the bloody massacre of over 4000 unarmed Indians and the capture of Inca Atahualpa.
