obliged the Mexicans to retire. General Taylor, fearing an attack from the cavalry upon Saltillo, immediately departed with a suitable escort to provide for its safety, and left General Wool to command during his absence.
After day dawn, on the 23d, Santa Anna again commenced the battle, by an attack upon the left wing, and, for a while, was withstood, until a portion of our forces, after a brave defence, mistaking an order to retire, for an order to retreat, became suddenly panic-struck, and fled from the field. At this moment, Taylor returned from Saltillo, and found the whole left of our position broken, whilst the enemy was pouring his masses of infantry and cavalry along the base of the eastern mountains towards our rear.
Meanwhile the battery in the road had repulsed the Mexican column sent against it, and spared three of its guns for service on the upper plain. The regiment, on the right of the stream, had been brought over to the left bank with its cannons, and was now, in position with two other regiments, facing the mountains, between which and this force, was a gap, through whose opening, the Mexicans steadily advanced under a dreadful fire. Nearly all the artillery had been concentrated at the same place, while, in other parts of the field and nearer to the hacienda of Buena Vista, in the American rear, were bodies of our cavalry, engaged in conflict with the advancing foe.
As Taylor approached this disastrous scene, he met the fugitives, and speedily made his dispositions to stop the carnage. With a regiment from Mississippi, he restrained a charge of Mexican cavalry, and ordered all the artillery, save four guns, to the rear to drive back the exulting Mexicans. This manœuvre was perfectly successful, and, so dreadfully was the enemy cut up by the new attack, that Santa Anna, availed himself of a ruse, by a flag of truce, in order to suspend the action, whilst he withdrew his men.
