He was soon to know, for strong men took the places of the animals, and the guns were hauled up and over the mountain by human hands. It was severe work, but it was done with eager enthusiasm, and a few hours later Ned was able to shout:

“Hurrah! Here we are, right in behind them. Hurrah for General Scott!”

Anything else that he might have felt like saying was drowned in the wild cheering which arose from thousands of soldiers, for there was no longer any need for silence or secrecy. That part of the Mexican army which had been posted beyond the head of the pass was taken utterly by surprise. Its commanders were for the moment unable to imagine whence had come this numerous body of United States infantry, which appeared so suddenly upon their unprotected flank. They therefore retreated, and the Mexican army was cut in two, so that all of it which had been stationed in the pass itself was caught as in a trap, and compelled to surrender. These trapped prisoners were about three thousand in number, and Ned kindly remarked concerning them:

“Oh, but ain’t I glad we didn’t have to kill ’em! We didn’t catch old Santa Anna himself, though. They say the Mexicans made him President for the battle of Angostura. I guess they wouldn’t have done it if they had waited till now.”

Whether or not he was correct in that calculation, the road to the city of Mexico seemed now to be open, unless the unfortunate republic could provide its President with another army. As for the American commander, his troops had more faith in him than ever, and with better reasons for it. It was afterward said that General Scott’s written orders for the battle of Cerro Gordo, and for others which followed, would answer very well for full reports of them after they were won.

The whole American army, except the garrison of Vera Cruz and small parties posted here and there along the road, had now escaped from the tierra caliente and the yellow fever. Immediately after the battle of Cerro Gordo, it marched on to the old city of Jalapa, among the mountains, where its quarters were cool and comfortable. Not many miles beyond Jalapa begins the great central tableland of Anahuac, and it was needful that the road leading into it should be taken possession of before the remnant of Santa Anna’s army should rally and construct barriers at positions from which it might prove difficult to drive them.

“If they do,” thought Ned, when he heard that matter under discussion by the soldiers, “I hope General Scott’ll send for me and the other engineers. I’d like to trap some more prisoners.”

He was not to have any such chance as that, but he was not to be idle altogether,—he and his engineers and his army. The division to which he and the Seventh Regiment belonged, under the command of General Worth, was shortly ordered on in the advance, to take and hold a strong position, known as the town and castle of Perote, and here there was indeed a long delay which was not engineered by the military forces of Mexico. The politicians and particularly the Congress of the United States had interfered very effectively on behalf of President Santa Anna. They had spent so much time in debates upon the legislation required for the gathering of fresh troops that the terms of enlistment of about half of the soldiers under Scott were expiring. It was of no use for him to move forward with a steadily vanishing army, and he was compelled to wait for months at and about Perote, until the new men could arrive and take the places of those who were going home.

“I guess I won’t enlist,” thought Ned, as that idea came again and again into his mind. “Neither mother nor father would wish me to do so. But I’m getting to be an old soldier, after all, and I won’t leave the Seventh till it gets into the city of Mexico.”

Whether it ever was to accomplish that feat was only to be determined by hard fighting, and there came a day, the 7th of August, 1847, when the division of General Worth, then encamped at Puebla, received orders to go forward. The entire army was to move, and General Scott had about as many soldiers with him as when he had landed at Vera Cruz in the spring.
