When the captain, resolved to carry out his duty thoroughly, entered the defile, a few well-aimed musket shots sufficed to destroy his weak escort, and the officer himself fell with a bullet through his chest. This brave officer was the first victim of this day, so fatal to the Spanish army. Unhappily, many others were fated to follow him. When the second detachment, which hurried up to the aid of the first, followed into the defile, the combat assumed the proportions of a battle.

Unhappily, the Spaniards having no infantry, and covered by invisible foes, fell one after the other with cries of impotent rage. On all sides bullets hailed on them, against which they had no protection, and were unable to reply. At times, a bullet, aimed haphazard, or guided by destiny, reached an object it was not aimed at. The shrubs parted, and a corpse rolling down the precipice fell crushed at the feet of the horses.

But for one man the Mexicans lost the Spaniards lost fifty. The fight was too unequal; it was no longer a combat, but a butchery. Suddenly, a tremendous shout was heard; the earth trembled beneath the hoofs of nearly two thousand horses, and General Cárdenas appeared, his face inflamed with noble ardour, his hair in disorder, leaning over his saddle, with his right arm extended, and his sword hanging from his wrist by a steel chain. Behind him came the whole Spanish army—the real battle was about to begin. The infantry arrived at the double on the flanks of the column, firing into the bushes and shrubs where they saw shots fired. The Spanish general, as an experienced leader, had made the best of a bad position. He had scarce entered the canyon with the cavalry, ere a large infantry corps, facing front and rear, occupied the gorge with two guns levelled on the plain. The general rightly conjectured that his enemies might try to catch him between two fires, which was really the plan of the Mexicans; for, no sooner had the infantry occupied the allotted post than Don Aurelio Gutiérrez, at the head of a considerable body of troops, infantry and cavalry, darted suddenly from the forest which had hitherto concealed him, and dashed furiously on the Spaniards, in order to dislodge them and drive them into the interior of the defile.

An obstinate hand to hand fight at once began. Here, at least, the combat was equal; for the Spaniards could see their enemies. Unhappily, the sharpshooters, concealed behind bushes, covered and decimated them, being most desperate against the artillerymen, whom they mercilessly shot down each time when they went up to reload their guns.

General Cárdenas, in spite of all obstacles—the bullets, lumps of rock, and whole trees showered down on his troops—crossed the whole defile with the rapidity of an arrow. He then perceived, some distance ahead, a barricade erected by the Mexicans to intercept his passage.

"There is the road, boys," the general shouted;

"Forward, forward!"

All dashed on to clear the barricade, but suddenly a battery was unmasked, and death passed along the Spanish ranks. Four howitzers, loaded with canister, thundered simultaneously, sweeping down whole lines of horsemen, and making a bloody gap through the entire column. Two-thirds of this magnificent Spanish cavalry were laid low. The general, lifting his horse with a prodigious effort, had forced the noble animal to mount the face of the barricade.

"Forward!" the general shouted, brandishing his sword over his head and digging his spurs into his horse's belly.

The animal made a last generous effort, and rolled dying in the centre of the Mexicans. General Cárdenas was already on his feet, sword in hand.
