Presently the flag hanging limp and lifeless at headquarters was seen to lift itself spiritedly from the staff. At the same instant was heard a dull, distant sound like the heavy breathing of some great animal below the horizon. The flag had lifted its head to listen. There was a momentary lull in the hum of the human swarm; then, as the flag drooped the hush passed away. But there were some hundreds more men on their feet than before; some thousands of hearts beating with a quicker pulse.
Again the flag made a warning sign, and again the breeze bore to our ears the long, deep sighing of iron lungs. The division, as if it had received the sharp word of command, sprang to its feet, and stood in groups at "attention." Even the little blacks got up. I have since seen similar effects produced by earthquakes; I am not sure but the ground was trembling then. The mess-cooks, wise in their generation, lifted the steaming camp-kettles off the fire and stood by to cast out. The mounted orderlies had somehow disappeared. Officers came ducking from beneath their tents and gathered in groups. Headquarters had become a swarming hive.
The sound of the great guns now came in regular throbbings--the strong, full pulse of the fever of battle. The flag flapped excitedly, shaking out its blazonry of stars and stripes with a sort of fierce delight. Toward the knot of officers in its shadow dashed from somewhere--he seemed to have burst out of the ground in a cloud of dust--a mounted aide-de-camp, and on the instant rose the sharp, clear notes of a bugle, caught up and repeated, and passed on by other bugles, until the level reaches of brown fields, the line of woods trending away to far hills, and the unseen valleys beyond were "telling of the sound," the farther, fainter strains half drowned in ringing cheers as the men ran to range themselves behind the stacks of arms. For this call was not the wearisome "general" before which the tents go down; it was the exhilarating "assembly," which goes to the heart as wine and stirs the blood like the kisses of a beautiful woman. Who that has heard it calling to him above the grumble of great guns can forget the wild intoxication of its music?
