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 goodwill.
