Commander-in-chief’s headquarters were to be at the palace on the plaza. On the way to it there was a square of trees, the Alameda. The Eighth Infantry had been drawn up on parade, in two ranks, in front of the church San José, opposite the Alameda. Colonel Clarke himself, of the Second Brigade, commanded.

“Present—arms!”

The drums beat a roll, every musket came to a rigid present, every sword to a salute, the colors dipped, and General Scott, looking like the old hero that he was, rode proudly along the line, his hand at his hat, his eyes a little misty. The regimental band played “Hail to the Chief.”

The Second Division of Regulars did not get in for a couple of days. General Childs, of the Third Artillery, had been left at Jalapa with about one thousand men, mainly Regulars of all the arms. Colonel Wynkoop and most of his First Pennsylvanians were still at Perote. Having only five thousand eight hundred active troops, General Scott was obliged to mark time at Puebla while awaiting reinforcements.

This was hard, for it gave General Santa Anna plenty of leisure in which to gather another army and complete his fortifications. And while Puebla was a pleasant place, there seemed to be a discouraging amount of sickness caused by the fruits and the water. One-fourth of the soldiers were in the hospital and many died.

The well were kept busy, for General Scott believed in exercise and drill. The army had its first opportunity since leaving Vera Cruz to drill together. Every day one or another of the brigades was manœuvred out upon the Puebla military drill grounds near the city walls; and three times a week there was a full division review, under the eyes of the commander-in-chief.

The Pueblans always crowded to witness the drills, and after watching they were free to admit that the Americans knew how to soldier.

It was no slouch of a job to be a drummer, as Jerry found out all over again. He himself had a lot to learn, if he would obey the drum major’s signals made with the tasseled staff. The drummer’s especial drill, for instance: Put up—drumsticks! Unsling—drums! Ground—drums! Take up—drums! Suspend—drums! Draw out—drumsticks! The marching signals: By the right flank, by the left flank, wheel to change direction, right oblique, left oblique, and so forth. The beats: The marching taps, ninety steps to the minute; the flam, or double beat, in pairs, at one hundred and ten steps to the minute, used in the evening retreat; the rolls, eighty beats to the minute for the troop call, and one hundred and ten to the minute for quick time and the salutes; the drag, one hundred and forty beats to the minute, for double-quick time, and the long roll, in sections as fast as one could work the drumsticks, for alarms.

Then there were the many calls: The general, for the whole camp to prepare to break up; the assembly, for the companies to fall in; to the color, for the companies to form regiments; the reveille, or first call, in the early morning, to wake the camp up; the tattoo, or last call, in the evening, to send the camp to bed; the drummers’ call, or musicians’ call; come for orders, and the call to the sergeants or corporals; the retreat call, for evening parade; and in the field the halt, the recall, the march in retreat, the run or charge, and the commence firing.

A drummer boy had to have a good ear and lots of constant practice to do all these things, with the drum major or some of the veteran drummers criticizing.
