'play the men into their last great fight'

Lee had come over the Chambersburg road from the west, riding up the long slope of South Mountain and then coming down to the clamorous plain with its great streaked blanket of battle smoke hiding the future and all its chances. Meade had come up the Emmitsburg road from the south to see the battle his advance guard had prepared for him, and they may have told him how the first Federal infantry, the Iron Brigade (wrecked now almost beyond repair), had left the road just below Gettysburg to go cross-lots over to Seminary Ridge, where the Yankee cavalry was trying to hold off the Confederate infantry. The Federal commander had sent the fife and drum corps to the head of the column to play the men into their last great fight, and it played "The Campbells Are Coming," the fifes shrilling out above the hard clatter of musket fire, the rattle of drums jarred off balance by the heavy concussion of artillery fire. ... There had been hard fighting that day of July 1, and harder fighting on July 2, and now it was July 3 and time for this bloody business to come to its climax.
