The siege continued with brisk firing on our side till the 27th of March, by which time a considerable breach had been made in the wall surrounding the city. Upon this General Morales, who was Governor of both the city and of San Juan de Ulloa, commenced a correspondence with General Scott looking to the surrender of the town, forts and garrison. On the 29th Vera Cruz and San Juan de Ulloa were occupied by Scott's army. About five thousand prisoners and four hundred pieces of artillery, besides large amounts of small arms and ammunition, fell into the hands of the victorious force. The casualties on our side during the siege amounted to sixty-four officers and men, killed and wounded.
CHAPTER X
MARCH TO JALAPA — BATTLE OF CERRO GORDO — PEROTE — PUEBLA — SCOTT AND TAYLOR
General Scott had less than twelve thousand men at Vera Cruz. He had been promised by the administration a very much larger force, or claimed that he had, and he was a man of veracity. Twelve thousand was a very small army with which to penetrate two hundred and sixty miles into an enemy's country, and to besiege the capital; a city, at that time, of largely over one hundred thousand inhabitants. Then, too, any line of march that could be selected led through mountain passes easily defended. In fact, there were at that time but two roads from Vera Cruz to the City of Mexico that could be taken by an army; one by Jalapa and Perote, the other by Cordova and Orizaba, the two coming together on the great plain which extends to the City of Mexico after the range of mountains is passed.
It was very important to get the army away from Vera Cruz as soon as possible, in order to avoid the yellow fever, or vomito, which usually visits that city early in the year, and is very fatal to persons not acclimated; but transportation, which was expected from the North, was arriving very slowly. It was absolutely necessary to have enough to supply the army to Jalapa, sixty-five miles in the interior and above the fevers of the coast. At that point the country is fertile, and an army of the size of General Scott's could subsist there for an indefinite period. Not counting the sick, the weak and the garrisons for the captured city and fort, the moving column was now less than ten thousand strong. This force was composed of three divisions, under Generals Twiggs, Patterson, and Worth. The importance of escaping the vomito was so great that as soon as transportation enough could be got together to move a division the advance was commenced. On the 8th of April, Twiggs's division started for Jalapa. He was followed very soon by Patterson, with his division. General Worth was to bring up the rear with his command as soon as transportation enough was assembled to carry six days' rations for his troops with the necessary ammunition and camp and garrison equipage. It was the 13th of April before this division left Vera Cruz.
The leading division ran against the enemy at Cerro Gordo, some fifty miles west, on the road to Jalapa, and went into camp at Plan del Rio, about three miles from the fortifications. General Patterson reached Plan del Rio with his division soon after Twiggs arrived. The two were then secure against an attack from Santa Anna, who commanded the Mexican forces. At all events they confronted the enemy without reinforcements and without molestation, until the 18th of April. General Scott had remained at Vera Cruz to hasten preparations for the field; but on the 12th, learning the situation at the front, he hastened on to take personal supervision. He at once commenced his preparations for the capture of the position held by Santa Anna and of the troops holding it.
Cerro Gordo is one of the higher spurs of the mountains some twelve to fifteen miles east of Jalapa, and Santa Anna had selected this point as the easiest to defend against an invading army. The road, said to have been built by Cortez, zigzags around the mountain-side and was defended at every turn by artillery. On either side were deep chasms or mountain walls. A direct attack along the road was an impossibility. A flank movement seemed equally impossible. After the arrival of the commanding-general upon the scene, reconnoissances were sent out to find, or to make, a road by which the rear of the enemy's works might be reached without a front attack. These reconnoissances were made under the supervision of Captain Robert E. Lee, assisted by Lieutenants P. G. T. Beauregard, Isaac I. Stevens, Z. B. Tower, G. W. Smith, George B. McClellan, and J. G. Foster, of the corps of engineers, all officers who attained rank and fame, on one side or the other, in the great conflict for the preservation of the unity of the nation. The reconnoissance was completed, and the labor of cutting out and making roads by the flank of the enemy was effected by the 17th of the month. This was accomplished without the knowledge of Santa Anna or his army, and over ground where he supposed it impossible. On the same day General Scott issued his order for the attack on the 18th.
The attack was made as ordered, and perhaps there was not a battle of the Mexican war, or of any other, where orders issued before an engagement were nearer being a correct report of what afterwards took place. Under the supervision of the engineers, roadways had been opened over chasms to the right where the walls were so steep that men could barely climb them. Animals could not. These had been opened under cover of night, without attracting the notice of the enemy. The engineers, who had directed the opening, led the way and the troops followed. Artillery was let down the steep slopes by hand, the men engaged attaching a strong rope to the rear axle and letting the guns down, a piece at a time, while the men at the ropes kept their ground on top, paying out gradually, while a few at the front directed the course of the piece. In like manner the guns were drawn by hand up the opposite slopes. In this way Scott's troops reached their assigned position in rear of most of the intrenchments of the enemy, unobserved. The attack was made, the Mexican reserves behind the works beat a hasty retreat, and those occupying them surrendered. On the left General Pillow's command made a formidable demonstration, which doubtless held a part of the enemy in his front and contributed to the victory. I am not pretending to give full details of all the battles fought, but of the portion that I saw. There were troops engaged on both sides at other points in which both sustained losses; but the battle was won as here narrated.
The surprise of the enemy was complete, the victory overwhelming; some three thousand prisoners fell into Scott's hands, also a large amount of ordnance and ordnance stores. The prisoners were paroled, the artillery parked and the small arms and ammunition destroyed. The battle of Buena Vista was probably very important to the success of General Scott at Cerro Gordo and in his entire campaign from Vera Cruz to the great plains reaching to the City of Mexico. The only army Santa Anna had to protect his capital and the mountain passes west of Vera Cruz, was the one he had with him confronting General Taylor. It is not likely that he would have gone as far north as Monterey to attack the United States troops when he knew his country was threatened with invasion further south. When Taylor moved to Saltillo and then advanced on to Buena Vista, Santa Anna crossed the desert confronting the invading army, hoping no doubt to crush it and get back in time to meet General Scott in the mountain passes west of Vera Cruz. His attack on Taylor was disastrous to the Mexican army, but, notwithstanding this, he marched his army to Cerro Gordo, a distance not much short of one thousand miles by the line he had to travel, in time to intrench himself well before Scott got there. If he had been successful at Buena Vista his troops would no doubt have made a more stubborn resistance at Cerro Gordo. Had the battle of Buena Vista not been fought Santa Anna would have had time to move leisurely to meet the invader further south and with an army not demoralized nor depleted by defeat.
After the battle the victorious army moved on to Jalapa, where it was in a beautiful, productive and healthy country, far above the fevers of the coast. Jalapa, however, is still in the mountains, and between there and the great plain the whole line of the road is easy of defence. It was important, therefore, to get possession of the great highway between the sea-coast and the capital up to the point where it leaves the mountains, before the enemy could have time to re-organize and fortify in our front. Worth's division was selected to go forward to secure this result. The division marched to Perote on the great plain, not far from where the road debouches from the mountains. There is a low, strong fort on the plain in front of the town, known as the Castle of Perote. This, however, offered no resistance and fell into our hands, with its armament.
