How did Gulliver communicate with the Lilliputians?

Before learning the language, Gulliver and the Lilliputians primarily communicated with gestures.

It appeared that he understood me well enough, for he shook his head by way of disapprobation, and held his hand in a posture to show that I must be carried as a prisoner. However, he made other signs, to let me understand that I should have meat and drink enough, and very good treatment. Whereupon I once more thought of attempting to break my bonds; but again, when I felt the smart of their arrows upon my face and hands, which were all in blisters, and many of the darts still sticking in them, and observing, likewise, that the number of my enemies increased, I gave tokens to let them know, that they might do with me what they pleased. Upon this the hurgo and his train withdrew, with much civility, and cheerful countenances.
