This was a day of intense anxiety and unrest in the valley of the Antietam. The people, who had lived in the farm houses that dotted the golden autumn landscape in this hitherto quiet community, had now abandoned their homes and given place to the gathering thousands who were marching to the stern command of the officers. It was a day of maneuvering and getting position preparatory to the coming mighty conflict. The two great armies now lay facing each other in a grand double line three miles in length. At one point they were so near together that the pickets could hear each other tread. It would require no prophet to foretell what would happen on the morrow. On the night of the 16th few officers found relief from anxiety, and it goes without saying that many a soldier on this particular night, with his mind on the battle which was to be fought on the morrow, did not close his eyes in slumber. Beautiful and clear the morning broke over the Maryland hills on the fateful 17th of September, 1862. The sunlight had not yet touched the crowned hilltops when artillery fire announced the opening of the battle. The contest was opened by Hooker with about 8,000 men. He made a vigorous attack on the Confederate left, commanded by Jackson, and was supported by Doubleday on the right, and Meade on the left. He had not gone far before the glint of the rising sun disclosed the bayonet points of a large Confederate force standing in a cornfield in his immediate front. This was a part of Jackson's corps, who had arrived during the morning of the 16th from the capture of Harper's Ferry, and had been posted in this position to surprise Hooker in his advance. The outcome was a terrible surprise to the Confederates. Hooker's batteries hurried into action and opened with canister on the cornfield. Hooker's object was to push the Confederates back through a line of woods and seize the Hagerstown road and the woods beyond in the vicinity of the Dunker church. Around this church on this fateful day the demon of war reigned supreme, and near this church stood the fine mansion of a Mr. Mumma, which was fired by a retreating column of Confederate troops and burned throughout the entire engagement. The Federal batteries on the east side of the Antietam poured an enfilading fire on Jackson that galled him very much. The Confederates stood bravely against this fire and made a determined resistance. Back, and still further back, were Jackson's men driven across the field, every stalk of corn in which was cut down by the shot and shell as closely as a knife could have done it. On the ground the fallen lay in rows, precisely as they had stood in the ranks. The Confederates were driven from the cornfield into a patch of woods. Hooker now advanced his center under Meade to seize the Hagerstown road and the woods beyond. They were met by a murderous fire from Jackson, who had just been reënforced by Hood's refreshed troops, who fell heavily upon Meade in the cornfield.
