Juan Sebastián Elcano
When the expedition wintered on the coast of Brazil the crews joined in a mutiny because they did not want to go any further. By this time Magellan and  Elcano no longer trusted each other. Magellan blamed Elcano for the mutiny and placed him in chains. One of Magellan's ships was wrecked in Brazil. By the time they reached the passage between the Atlantic Ocean and the Pacific Ocean, afterwards named the Strait of Magellan, one more ship had turned back. Magellan started through the strait in October 1520 taking a month to get through.
