About the middle of the afternoon our field-glasses picked up the Confederate head-of-column emerging from the range of hills previously mentioned, where it is cut by the Columbia road. But--ominous circumstance!--it did not come on. It turned to its left, at a right angle, moving along the base of the hills, parallel to our line. Other heads-of-column came through other gaps and over the crests farther along, impudently deploying on the level ground with a spectacular display of flags and glitter of arms. I do not remember that they were molested, even by the guns of General Wagner, who had been foolishly posted with two small brigades across the turnpike, a half-mile in our front, where he was needless for apprisal and powerless for resistance. My recollection is that our fellows down there in their shallow trenches noted these portentous dispositions without the least manifestation of incivility. As a matter of fact, many of them were permitted by their compassionate officers to sleep. And truly it was good weather for that: sleep was in the very atmosphere. The sun burned crimson in a gray-blue sky through a delicate Indian-summer haze, as beautiful as a day-dream in paradise. If one had been given to moralizing one might have found material a-plenty for homilies in the contrast between that peaceful autumn afternoon and the bloody business that it had in hand. If any good chaplain failed to "improve the occasion" let us hope that he lived to lament in sack-cloth-of-gold and ashes-of-roses his intellectual unthrift. The putting of that army into battle shape--its change from columns into lines--could not have occupied more than an hour or two, yet it seemed an eternity. Its leisurely evolutions were irritating, but at last it moved forward with atoning rapidity and the fight was on. First, the storm struck Wagner's isolated brigades, which, vanishing in fire and smoke, instantly reappeared as a confused mass of fugitives inextricably intermingled with their pursuers. They had not stayed the advance a moment, and as might have been foreseen were now a peril to the main line, which could protect itself only by the slaughter of its friends. To the right and left, however, our guns got into play, and simultaneously a furious infantry fire broke out along the entire front, the paralyzed center excepted. But nothing could stay those gallant rebels from a hand-to-hand encounter with bayonet and butt, and it was accorded to them with hearty good-will.
