"...he was killed in his own ship by stabs with a dagger by the chief constable of the fleet, who was sent to do this by [Magellan] in a boat with certain men" (The Genoese Pilot). This is an example of bad integrity from Magellan because he sent people to kill other people on the same ship.
"Magellan even relied on the taste of seawater to guide the fleet. As the water became fresher, he knew he was traveling inland, and once it turned salty, he realized he was approaching the Pacific on the western side of the strait" (Harper Collins). This is an example of good navigational skills because he is able to travel across the water and know where he's heading in a very unique way.
"Fearing that his fleet's supplies would not last the winter. Magellan put the crew on reduced rations" (The Genoese Pilot).
