replied, and it was soon apparent that the mortars were ineffective. Scott found himself compelled to ask for naval guns from the commander of the naval force, Commodore Matthew C. Perry. The six naval guns—three 32-pounders firing shot and three 8-inch shell guns—soon breached the walls and demoralized the defenders. On March 27, 1847, Vera Cruz capitulated.
Scott’s next objective was Jalapa, a city in the highlands about seventy-four miles from Vera Cruz on the national highway leading to Mexico City. Because on the coast the yellow fever season was approaching, Scott was anxious to move forward to the uplands at once, but not until April 8 was he able to collect enough pack mules and wagons for the advance. The first elements, under Bvt. Maj. Gen. David E. Twiggs, set out with two batteries. One was equipped with 24-lb. guns, 8-inch howitzers, and 10-inch mortars. The other was a new type of battery equipped with mountain howitzers and rockets, officered and manned by the Ordnance Corps. The rocket section, mainly armed with the Congreve, carried for service tests a new rocket, the Hale, which depended for stability not on a stick but on vents in the rear, which also gave it a spin like that of an artillery projectile. The rockets were fired from troughs mounted on portable stands. In addition to his two batteries, General Twiggs had a squadron of dragoons, in all about 2,600 men. He advanced confidently, though Scott had warned him that a substantial army commanded by Santa Anna lay somewhere ahead. On April 11, after Twiggs had gone about thirty miles, his scouts brought word that Mexican guns commanded a pass near the hamlet of Cerro Gordo.
Battle of Cerro Gordo
Near Cerro Gordo, the national highway ran through a rocky defile. On the left of the approaching Americans, Santa Anna with about 12,000 men had emplaced batteries on mountain spurs; and on the right of the Americans, farther down the road, his guns were emplaced on a high hill, El Telegrafo. He thus had firm command of the national highway, the only means he thought Scott had of bringing up his artillery.
Fortunately for Twiggs, advancing on the morning of April 12, the Mexican gunners opened fire before he was within range and he was able to pull his forces back. Two days later Scott arrived with reinforcements, bringing his army up to 8,500. A reconnaissance by Captain Lee showed that the rough country to the right of El Telegrafo, which Santa Anna had considered impassable, could be traversed to enable the Americans to cut in on the Mexican rear. The troops hewed a path through forest and brush; when they came to ravines, they lowered the heavy siege artillery by ropes to the bottom then hoisted it up the other side. By April 17 they were able to occupy a hill to the right of El Telegrafo, where they sited the rocket battery. Early on the morning of April 18 the battle began.
Though Santa Anna, by then forewarned, had been able to plant guns to protect his flank, he could not withstand the American onslaught. The Mexicans broke and fled into the mountains. By noon Scott’s army had won a smashing victory at a cost of only 417 casualties, including 64 dead. Santa Anna’s losses were estimated at more than a thousand.
Scott moved next morning to Jalapa. The way seemed open to Mexico City, only 170 miles away. But now he faced a serious loss in manpower. The term of enlistment of seven of his volunteer regiments was about to expire, and only a handful agreed to reenlist. The men had to be sent home at once to minimize the danger of yellow fever when they passed through Vera Cruz. The departure of the volunteers, along with wounds and sickness among the men remaining, reduced the army to 5,820 effectives.
In May Scott pushed forward cautiously to Puebla, then the second largest city in Mexico. Its citizens were hostile to Santa Anna and had lost hope of winning the war. It capitulated without resistance on May 15 to an advance party under General Worth. Scott stayed there until the beginning of August, awaiting reinforcements from Vera Cruz (which by mid-July more than doubled his forces) and awaiting the outcome of peace negotiations then under way. A State Department emissary, Nicholas P. Trist, had arrived on the scene and made contact with Santa Anna through a British agent in Mexico City. Trist learned that Santa Anna, elected President of Mexico for the second time, would discuss peace terms for $10,000 down and $1 million to be paid when a treaty was ratified. After receiving the down payment through the intermediary, however, Santa Anna made it known that he could not prevail upon the Mexican Congress to repeal a law it had passed after the battle of Cerro Gordo that made it high treason for any official to treat with the Americans. It was clear that Scott would have to move closer to the capital of Mexico before Santa Anna would seriously consider peace terms.
Contreras, Churubusco, Chapultepec
For the advance on Mexico City, Scott had about 10,000 men. He had none to spare to protect the road from Vera Cruz to Puebla; therefore, his decision to move forward was daring. It meant that he had Pillow’s Attack Advancing through the Woods of Chapultepec, James Walker, 1848 abandoned his line of communications or, as he phrased it, “thrown away the scabbard.” On August 7 Scott moved off with the lead division, followed at a day’s march by three divisions with a three-mile-long train of white-topped supply wagons bringing up the rear. Meeting no opposition—a sign that Santa Anna had withdrawn to defend Mexico City—Scott by August 10 was at Ayolta on a high plateau fourteen miles from the city.
Chapultepec and “Los Niños”
Chapultepec, an imposing castle nearly 200 feet above the Valley of Mexico, housed a military academy for young men. Nearly fifty cadets stayed to oppose an American advance. U.S. troops used scaling ladders to assault the castle and captured the garrison of 1,000 after a sharp fight. During the battle, five cadets were killed and a sixth wrapped himself in the Mexican flag and jumped to his death in the valley below. Simply known as “los niños” (the children), the cadets’ heroic actions proved a powerful image of Mexican resistance, pride, and nationalistic spirit.
The direct road ahead, entering the capital on the east, was barred by strongly fortified positions. Scott therefore decided to take the city from the west by a wide flanking movement to the south, using a narrow muddy road that passed between the southern shores of two lakes and the mountains and skirted a fifteen-mile-wide lava bed, the Pedregal, before it turned north and went over a bridge at Churubusco to the western gates of Mexico City.
The Pedregal, like the terrain around El Telegrafo, had been considered impassable; but Captain Lee again made a way through. He found a mule path across its southwestern tip that came out at the village of Contreras. Scott sent a force under Bvt. Maj. Gen. Gideon J. Pillow to work on the road, supported by Twiggs’ division and some light artillery. They came under heavy fire from a Mexican force under General Gabriel Valencia. Pillow, manhandling his guns to a high position, attacked on August 19; but his light artillery was no match for Valencia’s 68-lb. howitzer, nor his men for the reinforcements Santa Anna brought to the scene. American reinforcements made a night march in pouring rain through a gully the engineers had found through the Pedregal to fall upon the Mexicans’ rear on the morning of August 20 simultaneously with an attack from the front. In seventeen minutes the battle of Contreras was won, with a loss to Scott of only 60 killed or wounded; the Mexicans lost 700 dead and 800 captured, including 4 generals.
Scott ordered an immediate pursuit, but Santa Anna was able to gather his forces for a stand at Churubusco, where he placed a strong fortification before the town at the bridge and converted a thick-walled stone church and a massive stone convent into fortresses. When the first American troops rode up around noon, they were met by heavy musket and cannon fire. The Mexicans fought as never before; not until midafternoon could Scott’s troops make any progress. At last the fire of the Mexicans slackened, partly because they were running out of ammunition; and the Americans won the day, a day that Santa Anna admitted had cost him one third of his forces. About 4,000 Mexicans had been killed or wounded, not counting the many missing and captured. The battle had also been costly for Scott, who had 155 men killed and 876 wounded, approximately 12 percent of his effective
