In April 1500, the second Portuguese India Armada, headed by Pedro Álvares Cabral, with a crew of expert captains, including Bartolomeu Dias and Nicolau Coelho, encountered the Brazilian coast as it swung westward in the Atlantic while performing a large "volta do mar" to avoid becalming in the Gulf of Guinea. On 21 April 1500 a mountain was seen and was named "Monte Pascoal", and on 22 April Cabral landed on the coast. On 25 April the entire fleet sailed into the harbour they named "Porto Seguro" (Port Secure). Cabral perceived that the new land lay east of the line of Tordesillas, and sent an envoy to Portugal with the discovery in letters, including the letter of Pero Vaz de Caminha. Believing the land to be an island, he named it Ilha de Vera Cruz (Island of the True Cross). Some historians have suggested that the Portuguese may have encountered the South American bulge earlier while sailing the "volta do mar", hence the insistence of John II in moving the line west of Tordesillas in 1494—so his landing in Brazil may not have been an accident; although John's motivation may have simply been to increase the chance of claiming new lands in the Atlantic. From the east coast, the fleet then turned eastward to resume the journey to the southern tip of Africa and India. Cabral was the first captain to touch four continents, leading the first expedition that connected and united Europe, Africa, the New World, and Asia.
