how did gulliver try to save his country pride and honour in the face of intelligent inquiries of king?

Actually he Gulliver begins to think his perspective of his own country might have changed,

"And thus he continued on, while my colour came and went several times, with indignation, to hear our noble country, the mistress of arts and arms, the scourge of France, the arbitress of Europe, the seat of virtue, piety, honour, and truth, the pride and envy of the world, so contemptuously treated.

But as I was not in a condition to resent injuries, so upon mature thoughts I began to doubt whether I was injured or no. For, after having been accustomed several months to the sight and converse of this people, and observed every object upon which I cast mine eyes to be of proportionable magnitude, the horror I had at first conceived from their bulk and aspect was so far worn off, that if I had then beheld a company of English lords and ladies in their finery and birth-day clothes, acting their several parts in the most courtly manner of strutting, and bowing, and prating, to say the truth, I should have been strongly tempted to laugh as much at them as the king and his grandees did at me. Neither, indeed, could I forbear smiling at myself, when the queen used to place me upon her hand towards a looking-glass, by which both our persons appeared before me in full view together; and there could be nothing more ridiculous than the comparison; so that I really began to imagine myself dwindled many degrees below my usual size."
