Never did men march with cooler courage on more formidable lines of defense. Never did men wait an attack with cooler courage. Breastworks with abatis in front through which the mouth of cannon gaped; artillery and infantry on the right to enfilade; siege guns in the fort high above all, to sweep and annihilate. Schofield, born general that he was, simply lay in a rock-circled, earth-circled, water-circled, iron-and-steel-circled cage, bayonet and flame tipped, proof against the armies of the world! But Hood's brave army never hesitated, never doubted. Even in the matter of where to throw up his breastworks, Schofield never erred. On a beautiful and seemingly level plain like this, a less able general might have thrown them up anywhere, just so that they encircled the town and ran from river to river. But Schofield took no chances. His quick eye detected that even in apparent level plains there are slight undulations. And so, following a gentle rise all the way round, just on its top he threw up his breastworks. So that, besides the ditch and the abatis, there was a slight depression in his immediate front, open and clear, but so situated that on the gentle slope in front, down which the confederates must charge, the background of the slope brought them in bold relief--gray targets for the guns. On that background the hare would loom up as big as the hound. There were really two federal lines, an outer and an inner one. The outer one consisted of Bradley's and Lane's brigades which had retired from Spring Hill before the Confederate army, and had been ordered to halt in front of the breastworks to check the advance of the army. They were instructed to fire and then fall back to the breastworks, if stubbornly charged by greatly their superiors in numbers. They fired, but, true to American ideas, they disliked to retreat. When forced to do so, they were swept away with the enemy on their very heels and as they rushed in over the last line at the breastworks on the Columbia pike the eager boys in gray rushed over with them, swept away portions of Reilly's and Strickland's troops, and bayoneted those that remained. It was then that Schofield's heart sank as he looked down from the guns of the fort. But Cox had the forethought to place Opdyck's two thousand men in reserve at this very point. These sprang gallantly forward and restored the line. They saved the Union army!
