When the Army of the Shenandoah began to add its numbers to that already gathered at Manassas, a way out was found, so far at least as water was concerned, by sending the regiments and batteries, as fast as they came, to positions near Bull Run, some miles in front, where water at least was to be had. Baillie's command, worn out as it was, and suffering from hunger, was hurried through the camp and forced to march some weary miles farther before taking even that small measure of rest and sleep that the rapidly waning night allowed. It was nearly morning when the men and horses were permitted to drink together out of the muddy stream which was presently to mark the fighting-line between two armies in fierce battle for the mastery. It was nearly sunrise when a cannon-shot broke the stillness of a peculiarly brilliant Sunday morning and summoned all the weary men to their posts. A little later the battery with which we are concerned received its orders and was moved into position on the line. Its complement of commissioned officers being short, Sergeant-Major Baillie Pegram had command of the two guns which constituted the left section, and had a lieutenant's work to do. Troops were being hurried hither and thither in what seemed to Baillie's inexperienced eyes a hopeless confusion. But as he watched, he saw order grow out of the chaos,--a manifestation of the fact that there was one mind in control, and that every movement, however meaningless it might seem, was part and parcel of a concerted plan, and was intended to have its bearing upon the result. In the meanwhile the occasional report of a rifle had grown into a continuous rattle of musketry on the farther side of the stream, where the skirmishers were hotly at work, their firing being punctuated now and then by the deeper exclamation of a cannon. But the work of the day had not yet begun in earnest. The main line was not yet engaged, and would not be until the skirmishers should slowly fall back upon it from their position beyond the stream. To men in line of battle this is the most trying of all war's experiences. Then it is that every man questions himself closely as to his ability to endure the strain. Nerves are stretched to a tension that threatens collapse. Speech is difficult even to the bravest men, and the longing to plunge into the fray and be actively engaged is well-nigh irresistible. All this and worse is the experience even of war-seasoned veterans when they must stand or lie still during these endless minutes of waiting, while the skirmishers are engaged in front. What must have been the strain upon the nerves and brains of men, not one of whom had as yet seen a battle, and not one in ten of whom had even received his "baptism of fire" in a skirmish, as the men in Baillie's battery had done during the week before! It is at such a time, and not in the heat of battle, that men's courage is apt to falter, and that discipline alone holds them to their duty.
