Lemuel Gulliver, after being shipwrecked and abandoning the life boat, swims to the island of Lilliput, gets drunk by half a pint of brandy, and falls asleep in the grass. When he awakes his limbs and hair are bound to the ground, and he is surrounded by six inch tall people.
How did they do it? Let's assume they have the rope or chains that can't be broken easily by a normal human. But can the Lilliputs anchor those in the ground somehow so that this human can't free himself? If so, how? They don't have much time to build structures or massive foundations, let's grant them a few hours time for everything.
Let's assume that (as in the original story) the usual physics of our world apply, with the exception of the existence of six inch small people and plants and wildlife (and buildings, but none should not be around in this situation) scaled accordingly on this island.
