How did the Lilliputians take Gulliver to their capital?

First, the Lilliputians give Gulliver a drink with sleeping medicine in it. Once they are sure he is asleep, the Lilliputians, who are excellent mathematicians, transport Gulliver to the Capital. They use a large platform with twenty-two wheels pulled by dozens of four-and-a-half-inch horses, dragging Gulliver half of a mile. After he awakens, Gulliver finds that he is chained by his leg in the capital, but he is able to move in a circle of about two yards in diameter.
