At Cadereita, August 31, there were a thousand regular cavalry, and they were ordered to attack five hundred Texan horse then at China; but they accomplished nothing. The Americans march carelessly and in small bodies, observers reported; they loosen their arms and stoop down to drink at the first water; they sleep as if at home; they carry little ammunition; and their muleteers are hoping the train will be attacked. With such opportunities the six hundred troopers now under Canales were expected to do something; but that astute leader merely gave reasons why they could not. "Nothing, absolutely nothing will either the regular cavalry or the auxiliaries do against the enemy," exclaimed Ampudia bitterly; and on September 18 the whole mounted force of about three thousand meekly retreated to the town, leaving the roads practically open.[11.21] [TAYLOR PRESSES FORWARD] Early on September 12 all the pioneers of Taylor's army advanced from Cerralvo to prepare the road for his artillery and wagons. Ahead of them went a strange-looking company. Mounted on quick, tough horses and marching at will, the men were dressed as they pleased; but they agreed substantially on leggings, trousers belted round the waist, coarse red or blue shirts, and either a buckskin cap or a soft felt hat. Each carried a heavy rifle, a pouch of bullets, a large powderhorn and a bowie knife, and some had Colt revolvers. At every saddle-bow hung a braided lariat for a tether; and a bag of parched and pounded corn, together with whatever else the rider thought he needed, was bound to the saddle with thongs. This company was Captain McCulloch's rangers--a part of the First Texas regiment--Taylor's finest body of scouts; and they, assisted by a squadron of dragoons, covered the pioneers. On the following three days the First, Second and Field Divisions moved successively, carrying forty rounds of ammunition and rations for eight days, besides what went as freight; and only the sick, with a guard of two Mississippi companies, remained at Cerralvo.[11.22] The spell of Mexico, that was to charm away so often the pains of a hard existence, now fell upon the soldiers. The country became more fertile. One broad plain shone with Spanish dahlias, and curious trees and plants could be seen on all sides. Every few miles a stream of cool, sparkling water leaped across the road. In the morning a curtain of gray, thinning little by little, went slowly up at last, and revealed a world of hills, edged with burnished gold, where one or two, catching the sun aslant on a bare, crystalline side, would flash out amidst the lingering shadows in all the colors of a diamond; while, farther on, lilac mountain rose above lilac mountain and purple range looked over purple range until the crowning peaks touched the firmament. In one town after another grapes, figs and pomegranates delighted the eye, and, as an officer quoted to himself, "The air was heavy with the sighs of orange groves."
