against him. A ford was found near a mill, farther up the creek, and the officers reported the fact; but the arrival of the commanding general at this time prevented “Fighting Joe” from ordering an advance. The corps remained at this place until the afternoon of the next day, when orders came to cross the creek. The troops proceeded up the stream, and went over by a bridge and by the fords which had been examined by the staff officers. The outposts of the enemy were soon discovered and driven in, and the gallant corps continued to push the force in front till it was too dark to proceed any farther, at which time the resistance was fully equal to the power of the advancing host. This was the night before the great battle of Antietam. The weary troops lay down to rest in the cornfields where they had halted. The rebels were close by, and the pickets of the two armies were within gunshot range of each other. There was no rest yet for the general and his staff; for it was evident that a great battle was to be fought on the morrow—a battle on which the destinies of the Union depended. If the grand army of the Potomac was defeated, there would be nothing to stay the march of the invaders. The fair fields and the prosperous cities and towns of the North would then be open to them. The great heart of the nation, beating timidly as the rebel hordes advanced, sickened by previous disasters, might sink into despondency, and the bright hopes of a great people be forever crushed. It was no time for the brain of the army to slumber. “We want information,” said the general, after he had sent an aid to General McClellan to announce his intention to attack the enemy at the earliest dawn. The commander of the first army corps always wanted information, for he never moved in the dark. His brain and his arm were twin brothers in the conflict. Somers and Barkwood volunteered to procure the information, and left the headquarters for this purpose. It was useless to attempt to penetrate the heavy picket line of the rebels in the cornfields, and they descended the hill beyond a farm-house, till they came to a ravine through which flowed a considerable volume of water. “Here’s our chance,” said Somers, in a low tone. “That’s so; but you know I am a great coward, and this looks like risky business,” replied Captain Barkwood. “If you are, I think there is no need of more than one of us going through.”
