Shortly before this time General Beauregard had received from the signal officer, Captain Alexander, a dispatch, saying that from the signal station in the rear he had sighted the colors of this column, drooping and covered with the dust of journeyings, but could not tell whether they were the Stars and Stripes or the Stars and Bars. He thought, however, that they were probably Patterson's troops arriving on the field and reënforcing the enemy.
General Beauregard was momentarily expecting help from the right, and the uncertainty and anxiety of this hour amounted to anguish. Still the column pressed on. Calling a staff officer, General Beauregard instructed him to go at once to General Johnston, at the Lewis House, and say that the enemy were receiving heavy reënforcements, that the troops on the plateau were very much scattered, and that he would be compelled to retire to the Lewis House, and there re-form, hoping that the troops ordered up from the right would arrive in time to enable him to establish and hold the new line.
Meanwhile, the unknown troops were pressing on. The day was sultry, and only at long intervals was there the slightest breeze. The colors of the mysterious column hung drooping on the staff. General Beauregard tried again and again to decide what colors they carried. He used his glass repeatedly, and handing it to others begged them to look, hoping that their eyes might be keener than his.
General Beauregard was in a state of great anxiety, but finally determined to hold his ground, relying on the promised help from the right; knowing that if it arrived in time victory might be secured, but feeling also that if the mysterious column should be Federal troops the day was lost.
Suddenly a puff of wind spread the colors to the breeze. It was the Confederate flag,--the Stars and Bars! It was Early with the Twenty-Fourth Virginia, the Seventh Louisiana, and the Thirteenth Mississippi. The column had by this time reached the extreme right of the Federal lines. The moment the flag was recognized, Beauregard turned to his staff, right and left, saying, "See that the day is ours!" and ordered an immediate advance. In the mean time Early's brigade deployed into line and charged the enemy's right; Elzey, also, dashed upon the field, and in one hour not an enemy was to be seen south of Bull Run.
