CHAPTER XIII. 1847. SCOTT AT PUEBLA- TAMPICO ADVANCE AND ORIZABA TOPOGRAPHY OF THE VALLEY ROUTES ΤΟ THE CAPITAL -EL PEÑON TEZCOCO TAKEN SCOTT'S MEXICALZINGO CHALCO - OUTER AND INNER LINES AROUND THE CITY SCOTT'S ADVANCE BY CHALCO THE AMERICAN ARMY AT SAN AGUSTIN. THE American forces, as we have stated, had concentrated at Puebla on the main road to the city of Mexico, but their numbers had been thinned by desertion, disease and the return of many volunteers whose term of service was over or nearly completed. Meanwhile the Mexican army was increased by the arrival of General Valencia from San Luis with five thousand troops and thirty-six pieces of artillery, and General Alvarez with his Pinto Indians from the south and south-west, all of which, added to the regiments in the city and its immediate vicinity, swelled the numbers of the Mexican combatants to at least twenty-five or thirty thousand. It was discovered that General Taylor would not advance towards the south, and consequently the presence of Valencia's men was of more importance at the point where the vital blow would probably be struck. Whilst the events we have related were occurring in the interior, Commodore Perry had swept down the coast and captured Tobasco, which, however, owing to its unhealthiness, was not long retained by the Americans. But every other important port in the Gulf, from the Rio Grande to Yucatan, was in our possession, while an active blockade was maintained before those in the Pacific. Colonel Bankhead subsequently, occupied Orizaba, and seized a large quantity of valuable public property. It had been the desire of the American authorities, from the earliest period of the war, to draw a large portion of the means for its support from Mexico, but the commanding Generals finding the system not only annoying to themselves but exasperating to the people and difficult of accomplishment, refrained from the exercise of a right which invaders have generally used in other countries. Our officers, accordingly, paid for the supplies obtained from the natives. Nor did they confine this principle of action to the operations of the military authorities alone whilst acting for the army at large, but, wherever it was possible, restrained that spirit of private plunder and destruction which too commonly characterizes the common soldier when flushed with victory over a weak but opulent foe. When the ports of Mexico, however, had fallen into our possession and the blockade was raised, they were at once opened to the trade of all nations upon the payment of duties more moderate than those which had been collected by Mexico. The revenue, thus levied in the form of a military contribution from Mexican citizens upon articles they consumed, was devoted to the use of our army and navy. It was, in effect, the seizure of Mexican commercial duties and their application to our necessary purposes, and thus far, only, was the nation compelled to contribute towards the expense of the war it had provoked. Early in August, General Scott had been reinforced by the arrival of new regiments at Puebla, and on the 7th of that month, he resolved to march upon the capital. Leaving a competent garrison in that city, under the command of Colonel Childs, and a large number of sick and enfeebled men in the hospitals, he departed with about ten thousand eager soldiers towards the renowned Valley of Mexico. In the same month, three hundred and twenty-eight years before, Hernando Cortéz and his slender military train, departed from the eastern coasts of Mexico, on the splendid errand of Indian conquest. After fighting two battles, with the Tlascalans who then dwelt in the neighborhood of Puebla, and with the Cholulans whose solitary pyramid,—a grand and solemn monument of the past,— still rises majestically from the beautiful plain, he slowly toiled across the steeps of the grand volcanic sierra which divides the valleys and hems in the plain of Mexico. Patiently winding up its wooded sides and passing the forests of its summit, the same grand panoramic scene lay spread out in sunshine at the feet of the American General that three centuries before had greeted the eager and longing eyes of the greatest Castilian soldier who ever trod the shores of America. In order to comprehend the military movements which ended the drama of the Mexican war, it will be necessary for us to describe TOPOGRAPHY OF THE VALLEY OF MEXICO. 383 the topography of the valley with some minuteness, although it is not designed to recount, in detail, all the events and personal heroism of the battles that ensued. This would require infinitely more room than we can afford, and we are, accordingly, spared the discussion of many circumstances which concern the merits, the opinions, and the acts of various commanders. Looking downward towards the west from the shoulders of the lofty elevations which border the feet of the volcano of Popocatepetl, the spectator beholds a remarkable and perfect basin, enclosed on every side by mountains whose height varies from two hundred to ten thousand feet from its bottom. The form of this basin may be considered nearly circular, the diameter being about fifty miles. As the eye descends to the levels below, it beholds every variety of scenery. Ten extinct volcanoes rear their ancient cones and craters in the southern part of the valley, multitudes of lesser hills and elevations break the evenness of the plain, while, interspersed among its eight hundred and thirty square miles of arable land and along the shores of its six lakes of Chalco, Xochimilco, Tezcoco, San Cristoval, Xaltocan and Zumpango, stretching across the valley from north to south, are seen the white walls of ten populous cities and towns. In front of the observer, about forty miles to the west, is the capital of the Republic, while the main road thither descends. rapidly from the last mountain slopes, at the Venta de Cordova, until it is lost in the plain on the margin of Lake Chalco near the Hacienda of Buena Vista. From thence to the town of Ayotla it sweeps along the plain between a moderate elevation on the north and the lake of Chalco on the south. On the 11th of August, General Scott, after crossing the mountains, concentrated his forces in the valley. General Twiggs encamped with his division in advance, on the direct road, at Ayotla, near the northern shore of Lake Chalco; General Quitman was stationed with his troops a short distance in the rear; General Worth occupied the town of Chalco on the western shore of its lake, while General Pillow brought up the rear by an encampment near Worth. This position of the army commanded four routes to the capital whose capture was the coveted prize. The first of these, as well as the shortest and most direct, was the main post road which reaches the city by the gate or garita of San Lazaro on the east. After passing Ayotla this road winds round the foot of an extinct. volcanic hill for five miles when it approaches the sedgy shores and 384 ROUTES TO THE CAPITAL- EL PEÑON, marshes of Lake Tezcoco on the north, thence it passes over a causeway built across an arm of Tezcoco for two miles, and, by another causeway of seven miles finally strikes the city. The road is good, level, perfectly open and comfortable for ordinary travelling, but the narrow land between the lakes of Chalco and Tezcoco, compressed still more by broken hills and rocks, admits the most perfect military defence. At the end of the first causeway over the arm of Tezcoco which we have just described, is the abrupt oblong volcanic hill styled El Peñon, four hundred and fifty feet above the level of the lake, its top accessible in the direction of Ayotla at only one point, and surrounded by water except on the west towards Mexico. It is a natural fortress; yet Santa Anna had not neglected to add to its original strength, and to seize it as the eastern key of his defences. Three lines of works were thrown up, at the base, at the brow, and on the summit of the eminence. The works at the base, completely encircling El Peñon, consisted of a ditch fifteen feet wide, four and a half feet deep, and a parapet fifteen feet thick whose slope was raised eight and a half feet above the bottom of the ditch. Ample breastworks formed the other two lines of the bristling tiara. In addition to this, the causeway across the arm of Tezcoco, immediately in front, had been cut and was defended by a battery of two guns, while the fire from all the works, mounting about sixty pieces, swept the whole length of the causeway. The second road to the capital was by Mexicalzingo. After leaving Ayotla the highway continues along the main post road for six or seven miles and then deflects southwardly towards the village of Santa Maria, whence it pursues its way westwardly towards Istapalapan, but, just before reaching Mexicalzingo, it crosses a marsh formed by the waters of Lake Xochimilco, on a causeway nearly a mile long. This approach, dangerous as it was by its natural impediments, was also protected by extensive field works which made it almost as perilous for assault as the Peñon. The third route lay through Tezcoco. Leaving Chalco and the Hacienda of Buena Vista, it strikes off from the main route directly north, and passing through the town of Tezcoco, it sweeps westwardly around the shores of the lake of that name until it crosses the stone dyke of San Cristoval, near the lake and town of that name; thence, by a road leading almost directly south for fifteen miles, through the sacred town of Guadalupe Hidalgo, it enters the capital. It is an agreeable route through a beautiful country, yet extremely circuitous though free from all natural or artificial obstacles, until it reaches Santiago Zacualco within two miles of Guada |
