They went on discoursing, when Don Quixote, perceiving a thick cloud of dust arise right before them in the road, "The day is come," said he, turning to his squire, "the day is come, Sancho, that shall usher in the happiness which fortune has reserved for me; this day shall the strength of my arm be signalized by such exploits as shall be transmitted even to the latest posterity. Seest thou that cloud of dust, Sancho? It is raised by a prodigious army marching this way, and composed of an infinite number of nations."--"Why then, at this rate," quoth Sancho, "there should be two armies; for yonder is as great a dust on the other side." With that Don Quixote looked, and was transported with joy at the sight, firmly believing that two vast armies were ready to engage each other in that plain; for his imagination was so crowded with those battles, enchantments, surprising adventures, amorous thoughts, and other whimsies which he had read of in romances, that his strong fancy changed everything he saw into what he desired to see; and thus he could not conceive that the dust was only raised by two large flocks of sheep that were going the same road from different parts, and could not be discerned till they were very near; he was so positive that they were two armies, that Sancho firmly believed him at last. "Well, sir," quoth the squire, "what are we to do, I beseech you?"--"What shall we do," replied Don Quixote, "but assist the weaker and injured side? for know, Sancho, that the army which now moves towards us is commanded by the great Alifanfaron, emperor of the vast island of Taprobana; the other that advances behind us is his enemy, the king of the Garamantians, Pentapolin with the naked arm, so called because he always enters into the battle with his right arm bare."--"Pray, sir," quoth Sancho, "why are these two great men going together by the ears?"--"The occasion of their quarrel is this," answered Don Quixote: "Alifanfaron, a strong Pagan, is in love with Pentapolin's daughter, a very beautiful lady and a Christian; now her father refuses to give her in marriage to the heathen prince, unless he abjure his false belief and embrace the Christian religion."--"Burn my beard," said Sancho, "if Pentapolin be not in the right on it; I will stand by him, and help him all I may."--"I commend thy resolution," replied Don Quixote, "it is not only lawful, but requisite; for there is no need of being a knight to fight in such battles."--"I guessed as much," quoth Sancho; "but where shall we leave my ass in the meantime, that I may be sure to find him again after the battle; for I fancy you never heard of any man that ever charged upon such a beast."--"It is true," answered Don Quixote, "and therefore I would have thee turn him loose, though thou wert sure never to find him again; for we shall have so many horses after we have got the day that even Rozinante himself will be in danger of being changed for another."
