Santa Anna had supposed that a part of the American army occupied La Vaquería, some eight or ten miles west of Taylor’s actual position, and his intention had been to surprise it; but by February 11 he learned that all had concentrated at Agua Nueva. He now had the choice of three routes. One was the direct road to that point; the second would have taken him via La Hedionda to the rear of Buena Vista; and the third ran by the way of La Vaquería to the north of Agua Nueva.[16] Santa Anna desired, he said later, to pursue one of the lateral routes, and place himself between Taylor and Saltillo; but both of these routes were said to be circuitous, difficult if not impracticable for artillery, and perhaps inadequately supplied with water and provisions. He decided therefore to surprise Agua Nueva, believing that should his forces be seen, they would be regarded as a part of Miñón’s brigade.[17]

That general was ordered to proceed via La Hedionda to the American rear, and a little after noon on February 21—every soldier having been ordered to drink his fill, carry all the water he could, and take rations for the next two days—Santa Anna advanced. Agua Nueva was only some thirty-five miles away, and he expected to overwhelm it early the next morning. The march continued well into the night. At Carnero Pass, five or six miles from Taylor, the troops lay down by columns as they arrived—the cavalry still holding their reins. It was too cold for sleep, but they rested; and at six in the morning they rose in the deepest possible silence, and resumed their march.[17]

MONTEREY TO LA ENCARNACIÓN

The Americans had at last awakened, however. By February 19 Santa Anna was expected “hourly,” wrote Lieutenant Posey, and the next day Major McCulloch with his party of Texan scouts was despatched in the direction of La Encarnación, while Brevet Lieutenant Colonel May with about 400 dragoons and some field pieces proceeded toward La Hedionda.[18] The latter saw a cloud of dust in the direction of Potosí, fell in with a Mexican deserter[19]—who said Miñón was near and Santa Anna at La Encarnación—and reported at Agua Nueva before sunrise, February 21. At first his party were taken for Mexicans; and when the alarm subsided, it was followed by a solemn stillness, amidst which groups of officers could be seen talking eagerly in low tones with mysterious gestures.[22]

TAYLOR DRAWS BACK

Suddenly at about noon a solitary horseman on a jaded steed came down from the mountain, and made straight for the General’s tent, bringing word that a great Mexican army had been seen at La Encarnación. The combination of this report and May’s was understood to mean that Santa Anna intended to turn Agua Nueva, and before two o’clock the Americans took flight—that is the polite phrase—for Buena Vista.[20] Colonel Yell with his mounted Arkansas regiment was left behind to guard the stores, should Santa Anna permit this, until they could be removed;[21] the Second Kentucky and some guns were detached at La Encantada to support him; and the First Illinois under Colonel Hardin was posted at La Angostura. About midnight Yell’s pickets at Carnero Pass were driven in. Upon this, firing the buildings and the last of the stores, and abandoning some wagons, the troops hurried off, lighted on their way by roaring flames that filled the air with piles of lurid smoke and the mountains with fantastic shadows; and by morning all except Hardin’s command and the advanced pickets were at Buena Vista. Taylor, meanwhile, entrusting to Wool the disposition of the troops, marched with a strong escort of the three arms for Saltillo, to provide at this late day for the defence of that city against Miñón.[22]
