Unwilling to see the efforts which he could not aid and the slaughter which he could not stay, the colonel ascended the ridge at a point a quarter of a mile to the left, whence the Notch, itself invisible, but pushing up successive masses of smoke, seemed the crater of a volcano in thundering eruption. With his glass he watched the enemy's guns, noting as he could the effects of Coulter's fire--if Coulter still lived to direct it. He saw that the Federal gunners, ignoring those of the enemy's pieces whose positions could be determined by their smoke only, gave their whole attention to the one that maintained its place in the open--the lawn in front of the house. Over and about that hardy piece the shells exploded at intervals of a few seconds. Some exploded in the house, as could be seen by thin ascensions of smoke from the breached roof. Figures of prostrate men and horses were plainly visible. "If our fellows are doing so good work with a single gun," said the colonel to an aide who happened to be nearest, "they must be suffering like the devil from twelve. Go down and present the commander of that piece with my congratulations on the accuracy of his fire." Turning to his adjutant-general he said, "Did you observe Coulter's damned reluctance to obey orders?" "Yes, sir, I did." "Well, say nothing about it, please. I don't think the general will care to make any accusations. He will probably have enough to do in explaining his own connection with this uncommon way of amusing the rear-guard of a retreating enemy." A young officer approached from below, climbing breathless up the acclivity. Almost before he had saluted, he gasped out: "Colonel, I am directed by Colonel Harmon to say that the enemy's guns are within easy reach of our rifles, and most of them visible from several points along the ridge." The brigade commander looked at him without a trace of interest in his expression. "I know it," he said quietly. The young adjutant was visibly embarrassed. "Colonel Harmon would like to have permission to silence those guns," he stammered. "So should I," the colonel said in the same tone. "Present my compliments to Colonel Harmon and say to him that the general's orders for the infantry not to fire are still in force." The adjutant saluted and retired. The colonel ground his heel into the earth and turned to look again at the enemy's guns. "Colonel," said the adjutant-general, "I don't know that I ought to say anything, but there is something wrong in all this. Do you happen to know that Captain Coulter is from the South?" "No; _was_ he, indeed?" "I heard that last summer the division which the general then commanded was in the vicinity of Coulter's home--camped there for weeks, and--" "Listen!" said the colonel, interrupting with an upward gesture. "Do you hear _that_?"
