This is about the Portuguese explorer Ferdinand Magellan who attempted to find a western route to Asia from Spain. The expedition ran into a lot of problems and almost ended when Magellan himself died in battle whilst fighting natives.
The leadership of the expedition was then taken over by Juan Sebastián Elcano after several others failed to lead effectively and under him, the expedition eventually made it back to Spain with only one ship remaining of the fleet of 5 that had gone out.
