The banks of the Rio Trinidad are charming and deliciously diversified, bordered by rushes and reeds, and covered with mangroves, amid which sport thousands of flamingoes, cranes, herons, and wild ducks, which cackle noisily as they swim about in tranquil and transparent waters. About four miles from the sea, the banks rise gradually with insensible undulations, and form meadows covered with a tall and tufted grass, on which grow gigantic mahogany trees with their oblong leaves, and Peru trees with their red fruit, and magnolias, whose large white flowers shed an intoxicating perfume. All these trees, fastened together by lianas which envelop them in their inextricable network, serve as a retreat for a population of red and grey squirrels, that may be seen perpetually leaping from branch to branch, and of cardinal and mocking birds. The centzontle, the exquisite Mexican nightingale, so soon as night arrives, causes this picturesque solitude to re-echo with its gentle strains.
On the side of a hill that descends in a gentle slope to the river, glisten the white walls of some twenty cottages, with their flat roofs and green shutters, hanging in clusters from the scarped side of the hill, and hidden like timorous birds amid the foliage. These few cottages, built so far from the noise of the world, constitute the rancho of San Isidro.
Unfortunately for the inhabitants of this obscure nook, General Rubio, who felt the necessity of choosing for the site of his camp a strong strategic position, came suddenly to trouble their peace, and recall them rather roughly to the affairs of this world. In fact, from this species of eagles' nests, nothing was easier than for the General to send his columns in all directions. The Mexican army, therefore, marched straight on the rancho of San Isidro, where it arrived about midday. At the unexpected appearance of the troops, the inhabitants were so terrified that, hastily loading themselves with their most valuable articles, they left their houses and fled to hide themselves in the woods.
Whatever efforts the General might make to prevent them, or bring them back to their houses, the poor Indians offered a deaf ear to all, and were resolved not to remain in the vicinity of the troops. The Mexicans therefore remained sole possessors of the rancho, and at once installed themselves in their peaceful conquest, whose appearance was completely changed within a few hours. Tall trees, flowers, and lianas, nothing was respected. Enormous masses of wood lay that same evening on the ground, which they had so long protected with their beneficent shadow. The very birds were constrained to quit their pleasant retreat, to seek a shelter in the neighbouring forest.
When all the approaches to the forest had been cleared for a radius of about twelve hundred yards, the General had the place surrounded by powerful barricades, which transformed the peaceful village into a fortress almost impregnable, with the weak resources the insurgents possessed. The trees on the interior of the rancho were alone left standing, not for the purpose of affording, but to conceal from the enemy the strength of the corps encamped at this spot.
The house of the Indian Alcade, somewhat larger and more comfortably built than the rest, was selected by the General as headquarters. This house stood in the centre of the pueblo; from its azotea the country could be surveyed for a great distance, and no movement in Galveston roads escaped notice. The Texans could not stir without being immediately discovered and signaled by the sentry, whom the General was careful to place in this improvised observatory.
At sunset all the preliminary preparations were finished, and the rancho rendered safe against a coup de main. About seven in the evening the General, after listening to the report of the spies, was sitting in front of the house in the shadow of a magnificent magnolia, whose graceful branches crossed above his head. He was smoking a papillo, while conversing with several of his officers, when an aide-de-camp came up and told him that the person who had come to him that morning from the rebels, earnestly requested the favour of a few minutes' conversation. The General gave an angry start, and was about to refuse, when Colonel Melendez interposed, representing to the General that he could not do so without breaking his word, which he had himself pledged in the morning.
"As it is so," the General said, "let him come."
"Why," the Colonel continued, "refuse to listen to the propositions this man is authorized to offer you?"
"What good is it at this moment? There is always a time to do so if circumstances compel it. Now our situation is excellent; we have not to accept proposals, but, on the contrary, are in a position to impose those that may suit us."
