The City of Lilliput

As far as we know, they died. 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.
