in that quarter, they were opposed by our infantry and riflemen, who disputed successfully every inch of ground, until night closed and 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 panicstruck, 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 manoeuvre 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.
The transfer of so large a portion of Taylor's most efficient troops to the rear of his original line, had greatly weakened his front, in the best positions, where the inequalities of ground sustained his feeble numbers. Santa Anna was not unmindful of the advantage he had gained by these untoward events, and prepared all his best reserves, which were now brought for the first time into action, for another attack. Taylor had with him three regiments and four pieces of artillery. His front was rather towards the mountain than the open pass, while his back was towards the road
