The field was almost the same that the opposing forces had occupied a year and a month before when the first great battle of the war was fought. And many of them were the same men. Some who had engaged in that first conflict had gone home and had refused to reënlist; others had found soldiers' graves since then--but still others on both sides were here again, no longer the raw recruits that they were before, but, with their year of hard experience in the field, they were trained soldiers, equal to any in the world. The two armies faced each other in a line nearly five miles long. There was heavy fighting here and there along the line from the early morning hours, but no general engagement until late in the afternoon. The Union right pressed hard against the Confederate left and by ten o'clock had forced it back more than a mile. But the Confederates, presently reënforced in that quarter, hurled heavy masses of infantry against the Union right and regained much that it had lost. Late in the afternoon fresh regiments under Kearny and Hooker charged the Confederate left, which was swept back and rolled in upon the center. But presently the Southern General Hood, with his famous Texan brigade, rushed forward in a wild, irresistible dash, pressed Kearny back, captured one gun, several flags and a hundred prisoners. Night then closed over the scene and the two armies rested on their arms until the morning. The first day's battle is sometimes called the battle of Groveton, but usually it is considered as the first half of the second battle of Bull Run. It was a formidable conflict in itself. The Union loss was at least forty-five hundred men, the Confederate was somewhat larger. Over the gory field lay multitudes of men, the blue and the gray commingled, who would dream of battlefields no more. The living men lay down among the dead in order to snatch a little rest and strength that they might renew the strife in the morning. It is a strange fact that Lee and Pope each believed that the other would withdraw his army during the night, and each was surprised in the morning to find his opponent still on the ground, ready, waiting, defiant. It was quite certain that on this day, August 30th, there would be a decisive action and that one of the two armies would be victor and the other defeated. The two opposing commanders had called in their outlying battalions and the armies now faced each other in almost full force, the Confederates with over fifty thousand men and the Union forces exceeding their opponents by probably fifteen thousand men. The Confederate left wing was commanded by Jackson, and the right by Longstreet. The extreme left of the Union army was under Fitz John Porter, who, owing to a misunderstanding of orders, had not reached the field the day before. The center was commanded by Heintzelman and the right by Reno.
