Christopher Columbus set sail heading West to look for new lands. It was a daring move at a time of growing national imperialism and economic competition between states. It was risky and many thought that he would disappear of the edge of the world.
But Columbus remained focused even though he did not know exactly what he would find. In fact, he totally underestimated the circumference of the world and when he landed in the Bahamas he thought he had landed on the east Asian mainland.
As with all these voyages in history, Columbus prepared as best he could for the months ahead. In part he was preparing for the unknown, but there was a lot he knew he could plan for and he recognized that his team would need to be able to adapt and change as challenges arose.
