Signal station on Elk Mountain, Md., overlooking battlefield of Antietam, October 1862

To the hero of Antietam belongs the credit of first developing and fully appreciating the value of a corps of signalists to an army throughout its active operations in the field, and especially during a great battle. His signal officers were most intelligently and advantageously posted, and seldom, even in later campaigns, has their assistance to a commanding general been more valuable, or more frankly and handsomely acknowledged, than in the momentous struggle on the Antietam. At intervals along our line of battle, and on the most prominent points in the vicinity, were stationed the Federal Signal Officers, detecting by their skill, vigilance, and powerful glasses, every movement of the enemy, reporting them instantly by a few waves of their flags to the Union Commander, and in return, transmitting by the same means the orders to the subordinate generals, which were to check or defeat the manœuvres of the enemy. The adjoining sketch represents the most important of those signal look-outs, and was located on the summit of Elk Mountain, one of the South Mountain Range of the Blue Ridge, and overlooking the battle-field.

The Elk Mountain Signal Station was operated by Lieutenants Pierce and Jerome, and the view was taken whilst the former officer was receiving a dispatch from General McClellan, probably requesting further information in regard to some reported movement of his wary foe, or sending an important order to a Corps Commander.

A rebel correspondent of a Richmond paper, who claims to have been an eye-witness of that battle, thus writes on the succeeding day, of the part taken in it by the Signal Corps of the Union Army: “Their signal stations on the Blue Ridge commanded a view of our every movement. We could not make a manœuvre in front or rear that was not instantly revealed to their keen look-outs and as soon as the intelligence could be communicated to their batteries below, shot and shell were launched against the moving columns. It was this information, conveyed by the little flags upon the mountain-top, that no doubt enabled the enemy to concentrate his force against our weakest points, and counteract the effect of whatever similar movements may have been attempted by us.

      The remarks for this photo is from Alexander Gardner’s book, attributed just above the photo. The ‘Library of Congress, Miscellaneous document sources’ are simply the categories I used for this. I use the “miscellaneous document sources” category for all images now for tracking purposes. I probably should have a category “images,” instead to avoid confusion.
