During the Age of Discovery, mutiny meant open rebellion against a ship’s captain. This happened during Magellan’s journey and one mutineer was killed. Another mutineer was executed and 2 others were put on land and left there. After a mutiny on Henry Hudson’s "Discovery", Hudson and several others were left in the ocean in a small boat.
