The Supplejack reaches Baxada de Santa Fé—Plans for the protection of the fleet when returning—A night expedition to survey an island—Alarm—Magnificent exploit—Rocket battery peppers the batteries of San Lorenzo to some effect—Squadron passes unharmed—Escape of the boat—Monte Video reached.

The Supplejack continued her course up the river, and the following day got beyond the reach of Rosas’ flying artillery. Tom and Gerald, having been well fed during their adventures, were not much the worse for them, and after a good night’s sleep were well able to return to their duty. They of course had to repeat their adventures to their own messmates, and Needham and Snatchblock were also eager to hear all about them.

At last the brig reached Baxadar de Santa Fé, a town of some size, built partly at the foot and partly on the side of a lofty hill, which rises above the river. It is surrounded by corrals, or cattle-farms, where thousands of animals are slaughtered for the sake of their hides and tallow alone, which are shipped from the port. As there are not human mouths sufficient to consume the enormous quantities of beef, it is thrown away and carried off by vast flocks of gallinasos, caracaras, carrion crows, and other birds of prey, which hover over the country, their appearance and the odour arising from the putrefying flesh making the place far from agreeable. Here the Supplejack found a large fleet of merchantmen, which had been further increased by others which had come down the river. The question was how they all were to get back again to the sea. Two or three steamers, which came up after the Supplejack had suffered by a hot fire, opened on them from the batteries, newly thrown up by Rosas, several officers and men having been killed and wounded. The most formidable batteries were those at San Lorenzo, which were now completed, and it could not be expected that the fleet would be allowed to repass them without a strong opposition. Several plans were thought of, the bluejackets and marines might land and storm the batteries, but such an undertaking could only be carried out with great loss of life, as the troops of Rosas were not to be despised, and as the batteries were open in the rear they could not be held without a strong force.

Some weeks were spent at this most undelectable of places, so that everybody was eager to return. No one, however, knew what plan of operation had been determined on. At length the long-looked-for signal was hoisted, and the fleet of men-of-war and merchant-vessels got under weigh and proceeded down the stream. They presented a truly beautiful spectacle, as their clouds of white canvas covered the entire breadth of the river, and certainly never before had so many vessels floated together on its waters.

On the 31st of May they came to an anchor on the Entre Rios shore, about four miles above the formidable batteries of San Lorenzo. Still, no one besides the commander and a few officers entrusted with the secret knew what plan had been determined on. All that the rest were certain of was that a plan had been formed, and should it prove successful that the fleet might escape a severe handling, but otherwise that the guns of San Lorenzo, if well served, might sink or damage every ship in the squadron. Indeed, the deep-water channel, down which the ships must pass, was only about three hundred yards from the guns of the enemy, and which from their elevation could send a plunging fire directly down on their decks.

In front of the batteries, about twelve hundred yards from them, was one of an archipelago of islands, extending for some miles along the eastern or Entre Rios shore of the river, covered with trees, brushwood, and reeds. The passages between these islands and the eastern shore were much too shallow for the navigation of vessels of any size. Of necessity, therefore, the whole fleet had to pass under the high cliff of San Lorenzo, crowned by its formidable batteries. The skippers of the merchantmen were quaking in their shoes, believing that the men-of-war must be sent to the bottom and effectually block up the channel, so that they would be caught in a trap and fall into the hands of the tyrant Rosas.

All sorts of reports were flying about; some said that one hundred heavy guns were planted on the top of the cliffs, and that red-hot shot and missiles of all sorts would be showered down on them, but still the commodore kept the plan he proposed to adopt secret. The officers of the men-of-war, however, felt confident that whatever it was, it would most likely succeed.

Terence had returned to his ship: Jack was now alone. He was seated in his cabin, when a lieutenant from one of the steamers came on board:—

“Come, Rogers, you are wanted by the commodore, as you are not only to be let into the secret of the plan, but to assist in carrying it out.”

Jack, highly delighted, jumped up, and buckling on his sword accompanied his brother officer on board the flagship.
