On the sixth of February, the engineers who had charge of the mines gave notice that their work was completed. The following morning was named for the assault. The orders of the day prescribed that a general cannonade should open on the town at six in the morning. It was to continue an hour, when the mines were to be sprung. The artillery would then play for another hour, after which the signal for the attack would be given. The signal was to be the firing of one gun from each of the batteries, to be followed by a simultaneous discharge of all. The orders directed the troops to show no quarter to man, woman, or child. [Sidenote: EXPLOSION OF THE MINES.] On the seventh of February, the last day of the Carnival, the besiegers were under arms with the earliest dawn. Their young commander attracted every eye by the splendour of his person and appointments. He was armed _cap-à-pié_, and wore a suit of burnished steel, richly inlaid with gold. His casque, overshadowed by brilliant plumes, was ornamented with a medallion displaying the image of the Virgin.[229] In his hand he carried the baton of command; and as he rode along the lines addressing a few words of encouragement to the soldiers, his perfect horsemanship, his princely bearing, and the courtesy of his manners reminded the veterans of the happier days of his father, the emperor. The cavaliers by whom he was surrounded emulated their chief in the richness of their appointments; and the Murcian chronicler, present on that day, dwells with complacency on the beautiful array of southern chivalry gathered together for the final assault upon Galera.[230] From six o'clock till seven, a furious cannonade was kept up from the whole circle of batteries on the devoted town. Then came the order to fire the mines. The deafening roar of ordnance was at once hushed into a silence profound as that of death, while every soldier in the trenches waited, with nervous suspense, for the explosion. At length it came, overturning houses, shaking down a fragment of the castle, rending wider the breach in the perpendicular side of the rock, and throwing off the fragments with the force of a volcano. Only one mine, however, exploded. It was soon followed by the other, which, though it did less damage, spread such consternation among the garrison, that, fearing there might still be a third in reserve, the men abandoned their works, and took refuge in the town.
