It is amusing here to read in pretentious text-books that "Cortez now ironed Montezuma and made him pay a ransom of six hundred thousand marks of pure gold and an immense quantity of precious stones." That is on a par with the impossible fables which lured so many of the early Spaniards to disappointment and death, and is a fair sample of the gilded glamour with which equally credulous historians still surround early America. Moctezuma did not buy himself free,--he never was free again,--and he paid no ransom of gold; while as for precious stones, he may have had a few native garnets and worthless green turquoises, and perhaps even an emerald pebble, but nothing more. Just at this crisis in the affairs of Cortez he was threatened from another quarter. News came that Pamfilo de Narvaez, of whom we shall see more presently, had landed with eight hundred men to arrest Cortez and carry him back prisoner for his disobedience of Velasquez. But here again the genius of the conqueror of Mexico saved him. Marching against Narvaez with one hundred and forty men, he arrested Narvaez, enlisted under his own banner the welcome eight hundred who had come to arrest him, and hastened back to the City of Mexico. Here he found matters growing daily to more deadly menace. Alvarado, whom he had left in command, had apparently precipitated trouble by attacking an Indian dance. Wanton as that may seem and has been charged with being, it was only a military necessity, recognized by all who really know the aborigines even to this day. The closet-explorers have pictured the Spaniards as wickedly falling upon an aboriginal _festival_; but that is simply because of ignorance of the subject. An Indian dance is _not_ a festival; it is generally, and was in this case, a grim rehearsal for murder. An Indian never dances "for fun," and his dances too often mean anything but fun for other people. In a word, Alvarado, seeing in progress a dance which was plainly only the superstitious prelude to a massacre, had tried to arrest the medicine-men and other ringleaders. Had he succeeded, the trouble would have been over for a time at least. But the Indians were too numerous for his little force, and the chief instigators of war escaped. When Cortez came back with his eight hundred strangely-acquired recruits, he found the whole city with its mask thrown off, and his men penned up in their barracks. The savages quietly let Cortez enter the trap, and then closed it so that there was no more getting out. There were the few hundred Spaniards cooped up in their prison, and the four dykes which were the only approaches to it--for the City of Mexico was an American Venice--swarming with savage foes by the countless thousands.
