Lemuel Gulliver, surgeon to Antelope, sets sail to the South Sea on May 4th 1699. At first the voyage is without any mishap. What happens later on?

The ship encounters violent storms, has bad food, and weakens the crew (twelve crew members die) when the ship hits a rock and is split. Six of the crew members, including Gulliver, get into a small boat and row until they are overturned by a "sudden Flurry." Gulliver swims until he is nearly exhausted, at which point he finds an island, comes across a patch of grass, and sleeps for what he estimates is more than nine hours.
