The party now advanced towards the palace, which in the gloom of a starless night was still entirely hidden from their sight, save as a darker mass set square against the black vault of heaven. By this time Concha and La Giralda had taken the trembling portress by the arms, and were bringing her along in the van, whispering comfort in her ears all the way. The sergeant and Rollo came next, with Mortimer and Etienne behind, a naked blade in the hand of each, for Rollo had whispered the word to draw swords. This, however, El Sarria interpreted to mean his faithful Manchegan knife, to which he trusted more than to any sword of Toledo that ever was forged. At any other time they could not have advanced a score of yards without being brought to a stand-still by the challenge of a sentry, the whistle of a rifle bullet, or the simultaneous turning out of the guard. But now no such danger was to be apprehended. All was still as a graveyard before cock-crow. It is hard, in better and wiser days, when things are beginning to be traced to their causes, to give any idea of the effect of the first appearance of Black Cholera among a population at once so simple and so superstitious as that of rural Spain. The inhabitants of the great towns, the Cristino armies in the field, the country-folk of all opinions were universally persuaded that the dread disease was caused by the monks in revenge for the despites offered to them; especially by the hated Jesuits, who were supposed to have thrown black cats alive into rivers and wells in order to produce disease by means of witchcraft and diabolical agency. So universal was this belief that so soon as the plague broke out in any city or town the neighbouring monasteries were immediately plundered, and the priors and brethren either put to death or compelled to flee for their lives. Some such panic as this had stampeded the troops stationed in and about the little town of San Ildefonso, when the first cases of cholera proved fatal little more than a week before. A part of these had rushed away to plunder the rich monastery of El Parral a few miles off, lying in the hollow beneath Segovia. Others, breaking up into parties of from a dozen to a hundred, had betaken themselves over the mountains in the direction of Madrid. So the Queen-Regent and the handsome Senor Munoz remained perforce at La Granja, for the two-fold reason that the palace of Madrid was reported to be in the hands of a rebellious mob, and that the disbanding troops had removed with them every sort and kind of conveyance, robbed the stables of the horses, and plundered the military armoury of every useful weapon.
