how did gulliver reach the island of lilliput where was he housed in lilliput

Gulliver swims to the island after the shipwreck (everyone else dies).

Once on land, the Lilliputians dug him, after which, they use a large platform with twenty-two wheels pulled by dozens of four-and-a-half-inch horses to drag Gulliver half of a mile to the capiital.
