In the meantime all was bustle within the fort. The Spaniards had found out now that the Governor had entirely lost his nerve, and this increased the panic of the garrison. The men on watch amused themselves by telling thrilling and horrible stories of the various tortures inflicted by the pirates on their prisoners, and speculated as to the fate of the garrison of St. Jerome, whose fire had ceased when the sun went down. However, every one knew that Santa Teresa was safe enough, and that even if some bold spirits climbed up the steep path on the land side no great number could come on at the same time and so carry the place by assault.
At nightfall, Carlo, unseen by any one, slipped out of the fort; and, plunging into the wood, he was soon joined by the Indian Andreas, who was a fine fellow, a Christian, and, moreover, devotedly fond of the young Spaniard, who had always treated him with kindness. Andreas spoke fluent Spanish, from having been early taught by the Spanish priests, who had brought him up after his father's death.
'That's right, Andreas,' said Carlo, when he saw him. 'Now make haste and show me your path down to the river; the other one is watched by the slaves, and they might set the dogs on us by mistake. I reckon we can reach the swamps in two hours with your canoe, and you tell me that you are sure the enemy is encamped near there.'
'Yes, Señorito, that is the truth; my little boy brought me word. And I believe they are in great distress for want of food; but we shall see. Look, noble Carlo: I have brought my arrows; and woe to any one that tries to touch us!'
After some very difficult walking in the mazes of the forest, through which no one but an Indian could have steered, the two at last reached the river, which ran far below Santa Teresa; and though this stream was only navigable for canoes, it was often used by the Indians and Spaniards when in haste to reach the sea, instead of taking the longer journey by the land road. Andreas had powers of sight which appeared quite extraordinary to Carlo; and when the two were seated in the frail canoe, it was wonderful how the Indian paddled the boat, swiftly and surely, avoiding the rocks as if it were broad daylight, and never mistaking the many bends. Had Carlo been alone he would have grounded the boat half a dozen times, and not have reached his destination before daylight; but as it was, in two hours the boat glided swiftly into the midst of the mangrove swamp through which the river here made its way. All was quiet at first; the canoe did not even disturb the herons and pelicans which slept near by on the interlaced roots of the mangroves.
'If the pirates could have got into this swamp,' whispered Andreas, 'there would be no need of our cannon; but they are too crafty for that. They have doubtless seized a good guide who would not dare to betray them; otherwise they never could have reached Guana's Creek, where, I hear, they have encamped to-night.'
They drew up the canoe near to a great stump standing out in the water, and, mooring it there, Andreas stepped on to a dry piece of ground; then, stooping down, he listened intently, till like a stealthy animal he returned to Carlo.
'I am sure, Señorito, that I can hear the sound of the enemy. I must creep up through the grove and get to the higher ground; then I will return with news, if you will wait. I dare not let you come till I have seen how the land lies. Lie down in the canoe, and I will make haste. But cover yourself up, for the air is bad here, Señor; indeed you must chew this root, and then you will feel no harm.' And so saying, Andreas drew a dark-looking bit of root from his pocket, which was a secret remedy against the swamp malaria, known only to the Indians; then, walking quickly towards the jungle, he disappeared into the darkness.
Carlo had to wait what seemed to him a long time before Andreas came back; and what made it worse for him was the rain, which began to fall heavily. At last, when he was beginning to think his Indian friend had been caught by the pirates, he was startled by hearing a little splash in the water beside him, and in another moment Andreas himself was in the canoe.
'The young Señor did not hear me,' said the Indian, smiling at the start Carlo gave. 'It was to show him how well Andreas can walk in silence that I came so quietly.'
