To Mrs. Lyon.
Farmington, Miss., Tuesday a. m., May 20, 1862.— On Saturday, just at night, our whole force advanced about three miles to this place. We are about a mile south of our battle ground of the 9th inst. We bivouacked that night in line of battle and the next morning went to work and entrenched ourselves. This is done by digging ditches sufficiently wide for two ranks, and deep enough so that the men when standing can just see to shoot over the embankment of dirt from the trench which is thrown up on the outside. When the men sit down they are completely out of sight below the surface, and perfectly safe unless a ball or shell happens to fall directly in the trench. The artillery is posted directly behind us and shoots over our heads.
Behind our regiment are ten field pieces, one twelve-pound howitzer for shell, four ten-pound Parrott guns and five six-pound brass pieces. Then immediately on our left is a battery of four thirty-two-pound Parrott siege guns; and this is a specimen of our defenses through the whole line stretching miles away to the north.
We are waiting here now for the rebels to attack us, as our position is very strong. We are on an elevation, with a broad plateau of cleared fields before us which they must cross before they can reach us. There is constant firing of pickets and some cannonading up the line every day at different points. I hear the big guns talking now a few miles north of us. If they do not attack us here we shall soon move up still nearer to them and fortify another line. At the longest I think the struggle will be over here in the course of two weeks, perhaps sooner. We do not doubt our ability to defeat them. I feel calm in view of the approaching contest. My greatest solicitude is for the brave boys that I lead to battle; but they, and all of us, are engaged in a righteous cause and are in the hands of Him ‘Who doeth all things well.’ Now, be brave and hopeful. You will hear of the great battle many days before you know my fate, as I can not telegraph to you. I will write as quickly as I can. I am in perfect health.
