"It is quite evident that the Portuguese gunners have not much fight in them," Bull said.
"I am afraid it is the disaffection among their officers that is paralysing them," Terence said. "But I quite admit that it may be good policy to keep the men under cover. They really could do no good against the French batteries; which have all the advantage of position, as well as numbers and weight of metal; and it would certainly be well to reserve the troops till the French drive their trenches close up. If I thought that the silence of the guns on the walls were due to that, I should be well content; but I am afraid it is nothing of the sort. If the French keep up their fire, as at present, for another forty-eight hours, the place will throw open its gates. The inhabitants must be suffering frightfully. Of course, if Colonel Cox had men he could thoroughly rely upon, he would be obliged to harden his heart and disregard the clamour of the townspeople for surrender; but as the garrison is pretty certain to make common cause with them, it seems to me that the place is lost, if the bombardment continues."
In a short time, seeing that the working parties in the enemy's trenches made no attempt to push them farther forward, Terence withdrew the men from their exposed position on the rampartsleaving only a few there on the lookoutand told the rest to lie down on the inner slopes, so as to be in shelter from the French fire. Bull was in command of the force in the other redoubt, which was a quarter of a mile away. The redoubts were, however, connected by a deep ditch, so that communication could be kept up between them, or reinforcements sent from one to the other, unobserved by the enemy, except by those on one or two elevated spots.
All day the roar of the cannon continued. From a dozen points, smoke and flame rose from the city, and towards these the French batteries chiefly directed their fire, in order to hinder the efforts of the garrison to check the progress of the conflagration.
Just after dark, as Ryan and Terence were sitting down in an angle of the bastion to eat their supper, there was a tremendous roar; accompanied by so terrible a shock that both were thrown prostrate upon the ground with a force that, for the moment, half stunned them. A broad glare of light illuminated the sky. There was the rumble and roar of falling buildings and walls; and then came dull, crashing sounds as masses of brickwork, hurled high up into the air, fell over the town and the surrounding country. Then came a dead silence, which was speedily broken by the sound of loud screams and shouts from the town.
"It is just as we feared," Terence said as, bruised and bewildered, he struggled to his feet. "The magazine in the castle has exploded."
He ordered the bugler to sound the assembly and, as the men gathered, it was found that although many of them had been hurt severely, by the violence with which they had been thrown down, none had been killed either by the shock or the falling fragments. An officer was at once sent to the other redoubt, to inquire how they had fared; and to give orders to Bull to keep his men under arms, lest the French should take advantage of the catastrophe, and make a sudden attack.
"Ryan, do you take the command of the men, here, until I come back. I will go into the town and see Colonel Cox. I fear that the damage will be so great that the town will be really no longer defensible and, even if it were, the Portuguese troops will be so cowed that there will be no more fight left in them."
It was but five hundred yards to the wall. Terence was unchallenged as he ran up. The gate was open and, on entering, he saw that the disaster greatly exceeded his expectations. The castle had been shattered into fragments, the church levelled to the ground and, of the whole town, only six houses remained standing. Five hundred people had been killed.
The wildest confusion prevailed. The soldiers were running about without object or purpose, apparently scared out of their senses. Women were shrieking and wringing their hands, by the ruins of their houses. Men were frantically tugging at beams, and masses of brickwork, to endeavour to rescue their friends buried under the ruins. Presently he came upon Colonel Cox, who had just been joined by Captain Hewitt, the only British officer with him; who had instantly gone off to see the amount of damage done to the defences, and had brought back news that the walls
had been levelled in several places, and the guns thrown into the ditch.
Da Costa, Bareiros, and several other Portuguese officers were loudly clamouring for instant surrender and, the French shells again beginning to fall into the town, added to the prevailing terror. In vain the commandant endeavoured to still the tumult, and to assure those around him that the defence might yet be continued, for a short time; and better terms be obtained than if they were, at once, to surrender.
"Can I do anything, Colonel?" Terence said. "My men are still available."
