Battle is one trial of a soldier's quality; the march is another scarcely less severe. It tries endurance. Did you ever walk twenty miles in a day? It is not a long walk, and it may be delightful. But if you have had to carry even a light satchel or a fish-basket with your wading-boots, you know how the trifling load tells before the day is over; how you try it first in one position, then in another, and each seems worse than the last. Now suppose yourself loaded with knapsack containing your half of a shelter tent, your blanket, and a few other necessaries; haversack filled with three days' rations; cartridge-box with from forty to sixty rounds of ammunition; canteen of water, heavy musket and bayonet--fifty or sixty pounds in all. Your twenty miles will equal forty without the load; yes, more than that, even if you could walk at will and choose the easiest paths, which is precisely what the soldier cannot do. You must stumble over stony places, and push through briers, and wallow through swampy ground, or toil through soft fields; now and then you must wade a brook up to your knees or deeper, and for the next hour your shoes will weigh a pound more than they ought and gather mud and absorb gravel. Perhaps the regiment may take the high-road for a time, and the dust, beaten small and deep by preceding hoofs and wheels will enshroud you in a horrible cloud from which there is no escape, and penetrate every crevice of your clothing, and fill your eyes and ears and mouth and nostrils, and blind and choke you. There is no martial music to cheer you on; only the monotonous command, "Close up, men!" You lose consciousness of your soul, you know only that you have a body. Even that seems not to belong to you, it seems a badly oiled machine, part of a greater machine. And, then, on hot days the thirst! Your canteen will soon be exhausted; you will look with longing eyes at every stagnant puddle, and when a brook is reached--I have then seen men break through all restraint and madly dash at the water in spite of the drawn swords of officers vainly struggling to keep the ranks whole. As the day wanes the weariness amounts to agony. Every bone aches, every nerve is unstrung; strong men lose their self-control, sometimes almost their manhood. The moods of men on the march are a curious study. Perhaps early in the day the whole line will break into song, especially if the route happens to be through an inhabited town. The Maryland villages used to ring with "John Brown's body lies a-mouldering in the grave, But his soul goes marching on." Then silence will fall on every one as the burden begins to tell. Not a word will be spoken until some one breaks out with an oath, and then, all up and down the line, every man who ever swears will answer and the air will be blue with blasphemy. War takes no account of Sabbaths. We often marched day after day until we fairly lost track of time and you might hear a dialogue like the following:
