The general was not satisfied with the result. Two years after, he sent up another party, under Francisco Montaño, a cavalier of determined resolution. The object was to obtain sulphur to assist in making gunpowder for the army. The mountain was quiet at this time, and the expedition was attended with better success. The Spaniards, five in number, climbed to the very edge of the crater, which presented an irregular ellipse at its mouth, more than a league in circumference. Its depth might be from eight hundred to a thousand feet. A lurid flame burned gloomily at the bottom, sending up a sulphurous steam, which, cooling as it rose, was precipitated on the sides of the cavity. The party cast lots, and it fell on Montaño himself, to descend in a basket into this hideous abyss, into which he was lowered by his companions to the depth of four hundred feet! This was repeated several times, till the adventurous cavalier had collected a sufficient quantity of sulphur for the wants of the army.[238] This doughty enterprise excited general admiration at the time. Cortés concludes his report of it to the emperor with the judicious reflection that it would be less inconvenient, on the whole, to import their powder from Spain.[239] But it is time to return from our digression, which may perhaps be excused, as illustrating, in a remarkable manner, the chimerical spirit of enterprise--not inferior to that in his own romances of chivalry--which glowed in the breast of the Spanish cavalier in the sixteenth century. The army held on its march through the intricate gorges of the sierra. The route was nearly the same as that pursued at the present day by the courier from the capital to Puebla, by the way of Mecameca.[240] It was not that usually taken by travellers from Vera Cruz, who follow the more circuitous road round the northern base of Iztaccihuatl, as less fatiguing than the other, though inferior in picturesque scenery and romantic points of view. The icy winds, that now swept down the sides of the mountains, brought with them a tempest of arrowy sleet and snow, from which the Christians suffered even more than the Tlascalans, reared from infancy among the wild solitudes of their own native hills. As night came on, their sufferings would have been intolerable, but they luckily found a shelter in the commodious stone buildings which the Mexican government had placed at stated intervals along the roads for the accommodation of the traveller and their own couriers. It little dreamed it was providing a protection for its enemies. The troops, refreshed by a night’s rest, succeeded, early on the following day, in gaining the crest of the sierra of Ahualco, which stretches like a curtain between the two great mountains on the north and south. Their progress was now comparatively easy, and they marched forward with a buoyant step, as they felt they were treading the soil of Montezuma.
