Early in the 16^th century men were trying to reach Asia by travelling west from Europe. In order to find Asia they had to find a way past South Africa. The man who finally found the way from the Atlantic Ocean to the Pacific was Ferdinand Magellan.
Magellan sailed from Seville in August 1519 with five ships and about 280 men. Fourteen months later, after spending the severe （凌冽的） winter on the coast of Patagonia, he discovered the channel （海峡） which is now called Magellan Straits. In November 1520, after many months of dangers from rocks and storms, the three remaining ships entered the ocean on the other side of South America.
They then continued, hoping to reach Asia. But they didn’t see any land until they reached the islands off the coast of Asia. Before they arrived at these islands, later known as Philippines, men were dying of starvation. While they were in the Philippines., Magellan was killed in battle.
The remaining officers then had to get back to Spain. They decided to sail around Africa. After many difficulties, one ship with eighteen men sailed into Seville after leaving. They were all that remained of Magellan’s expedition （探险队）.
