'Carlo, here boy, quick: there is not a moment to spare. Take this note, climb down by the rock stairs, and deliver it safely to Don Meliros, the officer at the entrance fort--him you saw yesterday. If we are undone, don't let him waste any more precious lives. It is my duty to hold out till death, but his to save his garrison. Do you hear, boy? And, if you see him again, bid good-bye to your father. Tell him--nay, nothing more. But listen, Carlo: there is much danger in carrying this message, my boy; but do it fearlessly: it may prevent greater misfortunes for thee at least.'
Carlo did not hesitate a moment.
'Trust me, uncle: I will be as quick as possible, and come back to your side. Where shall I find you?'
'In the Corps du Garde, boy. Good heavens! the men on the north are giving way; that is our only strong point. Quick, boy: don't linger a moment!'
Don Alvarez hurried away, and Carlo ran straight for the church, which still remained untouched by the fire, and where the women and children were huddled together repeating a Litany aloud, not at all realising how great was their danger. Carlo knew that behind the church there was a piece of wall which he could scale, and which was not yet guarded by the pirates, all of whom were now concentrating their forces on the opposite side. From this spot Carlo could climb round the parapet, and reach the rocky stairs with his precious missive.
Being over-eager, however, Carlo found his task more difficult than he had expected; in his case haste made waste, for twice he fell back, and twice, being undaunted, he tried again. He heard a deafening shout behind him; alas! Carlo knew it was not the Spanish war-cry, and at last, in desperation, he made a final effort to lower himself to a ledge below without losing his balance, which would have caused him to be hurled down the face of the cliff; then, clinging like a goat, he crept along till he reached the stairs.
At this moment, when, feeling that he had already wasted much precious time, he was about to hurry down, a familiar voice close behind called him by name.
'Señor Carlo, wait a moment. How I have looked for you!' And then Harry Fenn, with greater skill than Carlo deemed possible, scrambled down from a point above him, and having joined him whispered anxiously, seizing him by the arm--
'Now, Señor, don't waste a moment: it is your only chance of safety. They know you have been fighting, and the castle and all the ammunition are now in the hands of the pirates.'
Carlo said nothing till both had reached the bottom; then, showing Harry his letter, he said his uncle had bade him deliver it. Before reaching the fort, however, they both saw that any message was now useless, for the Spaniards were already scrambling for the boats in order to fly up the river into the interior.
