D.Atahualpa
"On 17 November the Spaniards sacked the Inca army camp, in which they found great treasures of gold, silver, and emeralds. Noticing their lust for precious metals, Atahualpa offered to fill a large room about 22 feet (6.7 m) long and 17 feet (5.2 m) wide up to a height of 8 feet (2.4 m) once with gold and twice with silver within two months. It is commonly believed that Atahualpa offered this ransom to regain his freedom; however, it seems likelier that he did so to avoid being killed, as none of the early chroniclers mention any commitment by the Spaniards to free Atahualpa once the metals were delivered." -
The main difference between the plans of Columbus and da Gama mainly differ in the way they tried to reach the continent, while Columbus was going for a much riskier option and wanted to reach Asian through unexplored ocean by going in a westward direction, da Gama was going for a safer option by traveling near the continental mainlands and was going south to go around Africa and than eastward towards the already known direction for Asia. This lead to different results, Columbus unintentionally managed to discover a whole new world for the Europeans, while da Gama managed to open up a route towards Asia that was clear of any charges or passing through the waters of some empire.
