The expedition that departed from Sanlúcar de Barrameda on the 20th of September 1519 was a fragile coalition of five ships and approximately 270 men from a dozen different nations. The fleet's journey south along the coast of South America was plagued by storms and a lack of a clear passage.
On the morning of the 27th of April 1521, Ferdinand Magellan was struck by a bamboo spear and subsequently surrounded and killed by Datu Lapulapu's men on the island of Mactan.
