What was the great service performed by the Gulliver to the Emperor, and what was his reward?

Gulliver is awoken at midnight by hundreds of Lilliputians telling him that there is a fire in the empress's chamber in the palace. Gulliver hurries to be of assistance, but he quickly realizes that the thimble-sized buckets he is being passed are not having an affect on the raging fire. Thinking quickly, Gulliver chooses to urinate on the fire, putting it out completely and keeping it from spreading to the rest of the palace.

Gulliver returns to his home, where he awaits word of how the emperor and empress will react to his deed. He shortly learns that the empress feels abhorred.

Later, a high member of the court arrives to tell Gulliver that he is being charged with treason. Originally his sentence was to be death, but Redresal has argued successfully to have the sentence lessened to the removal of Gulliver's eyes. The charges Gulliver has been accused of are "making water" in the royal palace, refusing to reduce Blefuscu to a province, aiding the ambassadors of Blefuscu when they came to ask for peace, and planning to visit Blefuscu.

Not wanting to have his eyes put out, Gulliver flees to Blefuscu, where he is warmly received.
