State the circumstances which separate Gulliver from Captain Robinson?

Gulliver is separated from Captain Robinson when their ship was waylayed by pirates. After speaking with the Dutchman, Gulliver is set adrift in a small canoe.

But I had soon reason to repent those foolish words: for that malicious reprobate, having often endeavoured in vain to persuade both the captains that I might be thrown into the sea (which they would not yield to, after the promise made me that I should not die), however, prevailed so far, as to have a punishment inflicted on me, worse, in all human appearance, than death itself. My men were sent by an equal division into both the pirate ships, and my sloop new manned. As to myself, it was determined that I should be set adrift in a small canoe, with paddles and a sail, and four days’ provisions; which last, the Japanese captain was so kind to double out of his own stores, and would permit no man to search me. I got down into the canoe, while the Dutchman, standing upon the deck, loaded me with all the curses and injurious terms his language could afford.
