Magellan's Voyage
In 1519, Ferdinand Magellan sailed from Spain to find a western route to the Spice Islands. He took 237 men in five ships.
Each ship carried a supply of basic foods including cheese, flour, oil, meat and vegetables. There were also some live animals, including chickens.
The ships eventually reached the Spice Islands but only one continued the journey back to Spain. This was the Victoria. The sailors on the Victoria became very ill before they arrived home. They had bleeding gums and sores which would not heal, One sailor though, called Elcarno, used to eat spoonfuls of jam every day. He did not develop any of these symptoms.
