not bring all my army down this gorge, since there was no room for them to fight there, and I had another plan.  I sent some seven thousand men round the mountains, of which the secret paths were well known to them, bidding them climb to the crest of the precipices that bordered either side of the gorge, and there, at certain places where the cliff is sheer and more than one thousand feet in height, to make a great provision of stones.

The rest of my army, excepting five hundred whom I kept with me, I armed with bows and throwing spears, and stationed them in ambush in convenient places where the sides of the cliff were broken, and in such fashion that rocks from above could not be rolled on them.  Then I sent trusty men as spies to warn me of the approach of the Spaniards, and others whose mission it was to offer themselves to them as guides.

Now I thought my plan good, and everything looked well, and yet it missed failure but by a very little.  For Maxtla, our enemy and the friend of the Spaniards, was in my camp—­indeed, I had brought him with me that I might watch him—­and he had not been idle.

For when the Spaniards were half a day’s march from the mouth of the defile, one of those men whom I had told off to watch their advance, came to me and made it known that Maxtla had bribed him to go to the leader of the Spaniards and disclose to him the plan of the ambuscade.  This man had taken the bribe and started on his errand of treachery, but his heart failed him and, returning, he told me all.  Then I caused Maxtla to be seized, and before nightfall he had paid the price of his wickedness.

On the morning after his death the Spanish array entered the pass.  Half-way down it I met them with my five hundred men and engaged them, but suffered them to drive us back with some loss.  As they followed they grew bolder and we fled faster, till at length we flew down the defile followed by the Spanish horse.  Now, some three furlongs from its mouth that leads to the City of Pines, this pass turns and narrows, and here the cliffs are so sheer and high that a twilight reigns at the foot of them.

Down the narrow way we ran in seeming rout, and after us came the Spaniards shouting on their saints and flushed with victory.  But scarcely had we turned the corner when they sang another song, for those who were watching a thousand feet above us gave the signal, and down from on high came a rain of stones and boulders that darkened the air and crashed among them, crushing many of them.  On they struggled, seeing a wider way in front where the cliffs sloped, and perhaps half of them won through.  But here the archers were waiting, and now, in the place of stones, arrows were hailed upon them, till at length, utterly bewildered and unable to strike a blow in their own defence, they turned to fly towards the open country.  This finished the fight, for now we assailed their flank, and once more the rocks thundered on them from above, and the end of it was that those who remained of the Spaniards and their Indian allies were driven in utter rout back to the plain beyond the Pass of Pines.
