The city having refused to surrender, the bombardment opened on the morning of March 22d. The water-side of Vera Cruz was defended by the castle of San Juan d'Ulloa, built a century and a half before by Spain at enormous cost. Commodore Conner assisted throughout the four days that the cannonade lasted. The success of the bombardment made the Americans confident of capturing the castle by assault, and they were preparing to do so when the authorities proposed satisfactory terms of surrender, which took place March 29th.
The direct march upon the capital now began, with General Twiggs in command of the advance. The road steadily rises from the coast and abounds in passes and mountains, which offer the best kind of natural fortifications. When Twiggs reached one of these passes, named Cerro Gordo, he found that Santa Anna had taken possession of it with 15,000 troops. The whole American army numbered only 9,000, and it looked as if they were halted in front of an impregnable position, but it must be captured or the whole campaign would have to be abandoned.
BATTLE OF CERRO GORDO.
There was no hesitation on the part of our troops, who, under the lead of the bravest and most skillful of officers, attacked with their usual energy and daring. The Mexicans made the best defense possible, but within a few hours they abandoned every position and were driven in headlong confusion from the field. They lost 3,000 prisoners, among whom were five generals, while the escape of Santa Anna was so narrow that he left his cork leg behind.
The American army pressed on to Jalapa, which made no resistance, and furnished a large amount of supplies, and Puebla, a city of 80,000 inhabitants, was occupied on the 15th of May. There the ground was high and the air cool and salubrious. The men were exhausted from their arduous campaign, and Scott decided to give them a good rest, so as to be fully prepared for the final struggle. Besides it was necessary to receive reinforcements before venturing further. Santa Anna, realizing that the critical period of the struggle was at hand, put forth every energy to collect an army to beat back the invaders.
BATTLE OF CERRO GORDO.
"Captain Lee led the way, and showed the men just what to do. They lowered the cannons by ropes down the steep cliffs and hauled them up on the opposite hillside."
Early in August the American army had been increased to 11,000 men, and, leaving a small garrison at Puebla, Scott set out for the beautiful city of Mexico. No serious resistance offered until they reached Ayotla, fifteen miles from the capital. There it was found that the regular road bristled with forts, and, although there was no doubt that all could be carried, the American commander wisely decided to move his army around to the south, where he could advance over a comparatively undefended route. Without any difficulty he reached San Augustine, which was within ten miles of the capital.
Had the positions been changed, a force ten times as great as the Americans could not have captured the city of Mexico, and yet it fell before a force only one-third as numerous as the defenders.
