“Fit for the work?” turning to look at her.

“Yes, sir.”

“And you?”

She smiled; through the open tent a misty bar of sunshine fell across her face, turning the smooth skin golden. Outside a dismounted trooper on guard presented his carbine as the tall, young colonel strode out. An orderly joined him; they stood a moment consulting in whispers, then the orderly ran for his saddled horse, mounted, and rode off through the lanes of the cavalry camp.

From the tent door the Special Messenger looked out into the camp. Under the base of a grassy hill hundreds of horses were being watered at a brook now discolored by the recent rains; beyond, on a second knoll, the guns of a flying battery stood parked. She could see the red trimmings on the gunners’ jackets as they were lounging about in the grass.

The view from the tent door was extensive; a division, at least, lay encamped within range of the eye; two roads across the hills were full of wagons moving south and east; along another road, stretching far into the valley, masses of cavalry were riding—apparently an entire brigade—but too far away for her to hear the trample of the horses.

From where she stood, however, she could make out the course of a fourth road by the noise of an endless, moving column of horses. At times, above the hillside, she could see their heads, and the enormous canvas-covered muzzles of siege guns; and the racket of hoofs, the powerful crunching and grinding of wheels, the cries of teamsters united in a dull, steady uproar that never ceased.

From their camp, troopers of the Fourth Missouri were idly watching the artillery passing—hundreds of sunburned cavalrymen seated along the hillside, feet dangling, exchanging gibes and jests with the drivers of the siege train below. But from where she stood she could see nothing except horses’ heads tossing, blue caps of mounted men, a crimson guidon flapping, or the sun glittering on the slender, curved blade of some officer’s sabre as he signaled.

North, east, west, south—the whole land seemed to be covered with moving men and beasts and wagons; flags fluttered on every eminence; tents covered plowed fields, pastures, meadows; smoke hung over all, crowning the green woods with haze, veiling hollows, rolling along the railway in endless, yellow billows.

The rain had washed the sky clean, but again this vast, advancing host was soiling heaven and blighting earth as it passed over the land toward that beleaguered city in the South.
