The surrender of Harper's Ferry was a terrible blow to our cause. Had it continued in our possession it must have insured, with any respectable energy on the part of our commanders, the destruction of the rebel army in its retreat. As it was, our loss was over eleven thousand men, and a vast amount of war material.

Of course, the surrender of Harper's Ferry, at this critical period, was owing directly to the imbecility and cowardice, not to say treachery, of the officers in command at Harper's Ferry and on Maryland Heights. But, while we condemn the weakness and cowardice of these commanders, can we relieve from a share in the responsibility, the general who marched his army in pursuit of the enemy at a snail pace, traveling but six miles a day upon an average, when by a few brisk marches this important point might have been reinforced?

Early on the morning of the 17th, the Sixth corps was on its way, hastening to the scene of conflict which had commenced on the banks of Antietam creek. A part of the Seventy-seventh had constituted one-third of the picket line which had extended across the valley between the corps and Harper's Ferry.

These companies, by a hard march, much of it at double quick, succeeded in overtaking the division just as the Third brigade was making a charge over ground already thrice won and lost by Sumner's troops. Without waiting to form the companies, the detachment joined the command, and, all out of breath and faint from their forced march, rushed with their companies against the foe.

Among the delightful and fertile valleys which beautify the State of Maryland, none is more charming than the one through which the Antietam winds its tortuous course. Looking from some elevation down upon its green fields, where herds of sleek cattle graze, its yellow harvests glowing and ripening in the September sun; its undulating meadows and richly laden orchards; its comfortable farm houses, some standing out boldly upon eminences, which rise here and there, others half hidden by vines or fruit trees; the ranges of hills, rising on either side of the stream, diversified by charming vales or deep gullies; the turnpikes winding along the sides of the hills and through the valleys; the lovely stream itself, now flowing smoothly over its dark bed and anon tumbling noisily in rapids over a stony bottom, winding here far up to one range of hills and then turning back to kiss the base of the other; the whole scene is one of surpassing beauty, upon which the eye rests with untiring delight. Who would have selected this lovely valley as the scene of one of the most bloody struggles ever recorded? Who, looking down from some height of land on the morning of the 13th of September, would have dreamed that those stacks of grain, which dotted the fields here and there, would soon become the only protection from the heat of the sun and the storm of battle, to thousands of wounded, bleeding men? or, that from those lovely groves of oak and maple, now reposing like spots of beauty upon the landscape, were to belch forth fire and smoke, carrying destruction to thousands? Yet, here on these smiling fields, and among these delightful groves, one of the grand battles which should decide the march of events in the history, not only of our own country but of the world, was to be fought. These green pastures were to be stained with blood, and these peaceful groves marred and torn by shot and shell.

Driven from the towns along the Potomac, from Frederick, from Hagerstown, and from Boonsboro; and forced from the strong passes in the South Mountains, the detached portions of the rebel army were concentrated along the banks of the Antietam creek, in the vicinity of the little town of Sharpsburgh. Hither Jackson and Longstreet, Hill and Stuart, with their hosts, had gathered to offer combined resistance to the Union army; boastfully proclaiming that now, upon northern soil, they would hurl our army to final destruction. One hundred thousand men, flushed with recent victories, and eager for one grand crowning success, proudly defied the Union army.

Their position was well chosen. A line of steep hills, forming a half circle, with the convexity in front, rising at some distance back from the creek, and nearly parallel with it, afforded admirable advantages for posting batteries, in such a manner as to sweep the plain below, from right to left. Upon their left, wooded fields afforded protection to their infantry; while upon their right, the undulating nature of the grounds near the base of the hills, covered them from the fire of our guns. In their rear was Sharpsburgh; and two fine roads leading to the Potomac, afforded safe lines of retreat in case of disaster. From the crest of the hills, on which Lee had thus posted his army, the ground sloped gently back; concealing the movements of his forces from the view of the army in their front, allowing them to maneuver unobserved by their opponents. Owing also to the form of their line of battle, it was an easy matter to throw troops from one part to another. Thus, strongly posted and confidently anticipating victory, they waited the approach of the Union army.
