How does Gulliver create a playing field for the emperor's cavalry?

Gulliver creates a playing field for the emperor's cavalry by using sticks and his handkerchief. This act demonstrates Gulliver's resourcefulness and adaptability in unusual circumstances. He employs simple materials readily at hand to fashion a makeshift space suitable for the cavalry's exercise. The sticks likely serve to delineate boundaries or obstacles, while the handkerchief adds a touch of definition or flair to the playing field. This choice illustrates how Gulliver creatively engages with his environment to cater to the needs of the emperor's forces, reinforcing his resourceful character throughout the narrative.
