This was the bursting of the mine, which Don John, seeing Padilla well advanced in his assault, had now given the order to fire. In an instant came the terrible explosion, shaking Galera to its centre, rending the portion of the rock above the gallery into fragments, toppling down the houses on its summit, and burying more than six hundred Moriscoes in the ruins. As the smoke and dust of the falling buildings cleared away, and the Spaniards from below beheld the miserable survivors crawling forth, as well as their mangled limbs would allow, they set up a fierce yell of triumph. The mine, however, had done but half the mischief intended; for by a miscalculation in the direction, it had passed somewhat to the right of the castle, which, as well as the ravelin, remained uninjured. Yet a small breach had been opened by the artillery in the former; and what was more important, through the shattered sides of the rock itself a passage had been made, which, though strewn with the fallen rubbish, might afford a practicable entrance to the storming party.
The soldiers, seeing the chasm, now loudly called to be led to the assault. Besides the thirst for vengeance on the rebels who had so long set them at defiance, they were stimulated by the desire of plunder; for Galera, from its great strength, had been selected as a place of deposit for the jewels, rich stuffs, and other articles of value belonging to the people in the neighbourhood. The officers, before making the attack, were anxious to examine the breach and have the rubbish cleared away, so as to make the ascent easier for the troops. But the fierce and ill-disciplined levies were too impatient for this. Without heeding the commands or remonstrances of their leaders, one after another they broke their ranks, and, crying the old national war-cries, "_San Jago!_" "_Cierra Espana!_" "St. James!" and "Close up Spain!" they rushed madly forward, and, springing lightly over the ruins in their pathway, soon planted themselves on the summit. The officers, thus deserted, were not long in following, resolved to avail themselves of the enthusiasm of the men.
Fortunately the Moriscoes, astounded by the explosion, had taken refuge in the town, and thus left undefended a position which might have given great annoyance to the Spaniards. Yet the cry no sooner rose, that the enemy had scaled the heights, than, recovering from their panic, they hurried back to man the defences. When the assailants, therefore, had been brought into order and formed into column for the attack, they were received with a well-directed fire from the falconets, and with volleys of musketry from the ravelin, that for a moment checked their advance. But then rallying, they gallantly pushed forward through the fiery sleet, and soon found themselves in face of the breach which had been made in the castle by their artillery. The opening, scarcely wide enough to allow two to pass abreast, was defended by men as strong and stout-hearted as their assailants. A desperate struggle ensued, in which the besieged bravely held their ground, though a Castilian ensign, named Zapata, succeeded in forcing his way into the place, and even in planting his standard on the battlements. But it was speedily torn down by the enemy, while the brave cavalier, pierced with wounds, was thrown headlong on the rocky ground below, still clutching the standard with his dying grasp.
