Numbers 175. Report of col. Silas Colgrove, Twenty-seventh Indiana Infantry, of the battle of Antietam.


September 22, 1862.

SIR: I be leave to submit the following report of the part taken by my regiment (Twenty-seventh Indiana Volunteers) in the action of the 17 the instant, near Sharpsburg, Md.:

About sunrise int he morning I received orders to get my regiment under arms. I immediately formed my regiment in column by battalions closed in mass, right in front. The brigade was promptly moved to the front, the Second Massachusetts occupying the right, the Third Wisconsin second, my regiment third, the One hundred and seventh New York fourth, and the Thirteenth New Jersey the left or rear.

Immediately in front or beyond the corn-field, upon open ground at a distance of about 400 yards,were three regiments in line of battle and farther to the right, on a high ridge of ground, was still another regiment in line diagonally to our line. When we first took our position it was impossible to immediately open fire upon the enemy without firing into our own troops, who were retreating out of the corn-field. As soon as these troops had field past my left, I immediately ordered my regiment to fire, which was done in good order. The firing was very heavy on both sides, and must have continued for more than two hours without any change of position on either side. It was very evident from the firing that the enemy was greatly superior in numbers at this point. the only force during this time place engaged was the tree old regiments of
