in half. (The details of the eastern division implicit in the Tordesillas treaty would later be formalized in the 1529 Treaty of Zaragoza.) King Manuel saw all of this as an insult and did everything in his power to disrupt Magellan's arrangements for the voyage. The Portuguese king allegedly ordered that Magellan's properties be vandalized as it was the coat of arms of the Magellan displayed at the family house's façade in Sabrosa, his home town, and may have even requested the assassination of the navigator. When Magellan eventually sailed to the open seas in August 1519, a Portuguese fleet was sent after him, though it failed to capture him. Magellan's fleet consisted of five ships carrying supplies for two years of travel. The crew consisted of about 270 men of different origins, though the numbers may vary downwards among scholars based on contradicting data from the many documents available. About 60 percent of the crew were Spaniards from virtually all regions of Castile. Portuguese and Italian followed with 28 and 27 seamen respectively, while mariners from France (15), Greece (8), Flanders (5), Germany (3), Ireland (2), England and Malaysia (one each) and other people of unidentified origin completed the crew. Voyage The fleet left Spain on 20 September 1519, sailing west across the Atlantic toward South America. In December, they made landfall at Rio de Janeiro. From there, they sailed south along the coast, searching for a way through or around the continent. After three months of searching (including a false start in the estuary of Río de la Plata), weather conditions forced the fleet to stop their search to wait out the winter. They found a sheltered natural harbor at the port of Saint Julian, and remained there for five months. Shortly after landing at St. Julian, there was a mutiny attempt led by the Spanish captains Juan de Cartagena, Gaspar de Quesada and Luis de Mendoza. Magellan barely managed to quell the mutiny, despite at one point losing control of three of his five ships to the mutineers. Mendoza was killed during the conflict, and Magellan sentenced Quesada and Cartagena to being beheaded and marooned, respectively. Lower-level conspirators were made to do hard labor in chains over the winter, but were later freed. During the winter, one of the fleet's ships, the Santiago, was lost in a storm while surveying nearby waters, though no men were killed.
