Close behind him, too, came the Americans. Already a day's march apart, Worth's two brigades maintained that interval for some time, followed by Quitman with the New York and South Carolina regiments at an equal distance. For six or eight miles from Perote the country was highly cultivated and already brown with ripening wheat and barley; but then came a sandy, arid region where steep, conical hills of bare limestone, calcined like those of the Rhone valley, shot up from a wide, smooth plain in extravagant confusion, and appeared to bar the way. Hacienda buildings that were crenellated fortresses could be seen here and there; but the only cheering sights were glimpses of silvery Orizaba, a number of smaller mountains with Italian profiles, forked lightnings at play sometimes in the black clouds, and mirages of gardens, lakes and sylvan shores that deceived even the most experienced.[24.14] At Ojo de Agua, about thirty-five miles from Perote, a spring of water almost as large as the fountain of Vaucluse gave rise to a creek, which watered palmettoes and extensive meadows. Eight or nine miles farther on, the troops came to dark Nopalucan, which lay reclining on a comfortable eminence and viewing complacently its fertile valley. Then some twenty-five miles of romantic scenery brought them to Amozoc, a manufacturing town of 2000 souls ten or eleven miles from Puebla, and here Worth, who had made easy marches for two days in order to lessen the interval between him and Quitman, halted his now united brigades at noon on the fourteenth to await that officer, and to give his own dusty division time to "brush up."[24.14] Santa Anna, after sending his infantry and artillery toward Mexico early that morning, had moved off with some 2000 cavalry to surprise Quitman, supposing that he would be at his usual distance behind Worth, and that Worth had continued his march. The consequence was that his troops, finding themselves at about eight o'clock within half a mile or so of Duncan's battery and under fire, scattered promptly up the hills and into the woods. Divining correctly that he would reassemble them to strike at Quitman, Worth despatched forces at once to the rear; but Quitman, who had set out in the night, was now only two miles distant, and, warned by the artillery fire, had prepared to meet the enemy. Santa Anna therefore accomplished nothing more than to fatigue his men, and give them a superfluous lesson in running away; and after returning with them to Puebla for the night, he evacuated that city before daybreak the next morning with one more failure to his account.[24.14]
