Which navigator carried out the second circumnavigation of the world in a single expedition?
Francis Drake. In 1577, half a century after Magellan's expedition, Francis Drake set sail from Plymouth with five ships and 164 men. During his expedition, he captured several Portuguese and Spanish Ships (including treasury ship with 36 kg of gold) and sacked Valparaiso. After his return, the Queen's half-share of the cargo surpassed the rest of the crown's income for that entire year.
