The Civil War: A Narrative: Volume One: Fort Sumter to Perryville by Shelby Foote:
Everything was moiling confusion in the camps along the creekbed, guns booming north and south as men came out of their blankets in various stages of undress, tousle-haired, half asleep, and badly frightened. Under the stress of that first panic many fled. Some returned, rather shamefaced. Others ran, and kept on running, right out of the war. Yet those who stood were hard-core men from Arkansas and Louisiana, Texas and Missouri, wanting only to be told what to do. McCulloch and his aides soon established a line of resistance, and these men fell in eagerly. Price had yielded the command, but he was there, too, his white hair streaming in the wind as he rode up and down the line of his rallied Missourians, shouting encouragement. Under such leadership, the Southerners assembled in time to meet the attack from both directions. The battle that followed set the pattern for all such encounters in the West.
Few of the romantic preconceptions as to brilliant maneuver and individual gallantry were realized. Fighting at close quarters because of the short-range Confederate flintlocks and muzzle-loading fowling pieces, a regiment would walk up to the firing line, deliver a volley, then reload and deliver another, continuing this until it dissolved and was replaced by another regiment, which repeated the process, melting away in the heat of that furnace and being in turn replaced. No fighting anywhere ever required greater courage, yet individual gallantry seemed strangely out of place. A plume in a man’s hat, for example, accomplished nothing except to make him a more conspicuous target. Nor did the rebel yell ring out on the banks of Wilson’s Creek. There was little cheering on either side; for a cheer seemed as oddly out of place as a plume. The men went about their deadly business of firing and reloading and melting away in a grim silence broken only by the rattling crash of musketry and the deeper roar of guns, with the screams of the injured sometimes piercing the din. Far from resembling panoplied war, it was more like reciprocal murder.
