The fleet sailed further and further south, avoiding the Portuguese territories in Brazil, and became the first to reach Tierra del Fuego at the tip of the Americas. On October 21, starting in Cape Virgenes, they began an arduous trip through a 373-mile (600 km) long strait that Magellan named "Estrecho de Todos los Santos", the modern Strait of Magellan. On November 28, three ships entered the Pacific Ocean—then named "Mar Pacífico" because of its apparent stillness. The expedition managed to cross the Pacific. Magellan died in the battle of Mactan in the Philippines, leaving the Spaniard Juan Sebastián Elcano the task of completing the voyage, reaching the Spice Islands in 1521. On September 6, 1522 "Victoria" returned to Spain, thus completing the first circumnavigation of the globe. Of the men who set out on five ships, only 18 completed the circumnavigation and managed to return to Spain in this single vessel led by Elcano. Seventeen others arrived later in Spain: twelve captured by the Portuguese in Cape Verde some weeks earlier, and between 1525 and 1527, and five survivors of the "Trinidad". Antonio Pigafetta, a Venetian scholar and traveller who had asked to be on board and become a strict assistant of Magellan, kept an accurate journal that become the main source for much of what we know about this voyage.
