Seeking a westward route to the Spice Islands (Moluccas), Magellan sailed from Sanlúcar de Barrameda in September 1519 with five ships and some 270 men. Following the South American coast, he passed through the strait that bears his name in October–November 1520, and crossed a vast ocean amid starvation and scurvy, naming it the Pacific. He reached the Philippines in March 1521 but was killed on Mactan in April. Elcano took the Victoria to the Moluccas, loaded spices and sailed home across the Indian Ocean and round the Cape of Good Hope, arriving with eighteen men on 6 September 1522. The voyage demonstrated that the oceans were connected and first revealed the immense size of the Pacific.
