A Relic of the battle of Shiloh.
--The following letter, from a Federal officer to his sister, was picked up in one of the enemy's tents after the battle of Shiloh, and forwarded to the N. O. True Delta for publication. This writer, like all those whose epistles have fallen into Southern hands, is very sanguine of the success of the North in its work of subjugation. He tells his sister not to be uneasy, for as soon as they "drown out the rebellion" he will return home "crowned with honor." If Mr. Wilcox is not more of an adept with the sword than his shows himself to be with the pen, the cause he exposes will not benefit much by his efforts. We print the letter verbalism.--I am sorry to tell you that we are under marching orders to go down the Tennessee river to whip those infernal rebels You must not be uneasy, for as soon as we drown out the rebellion, I will come back, crowned with honor. I do not think that the rebels can stand it much longer. Do not write until you get another letter from me. My company is doing fine. My first lieutenant died of his wound. I wish old Davis and his rebellion were in hell fire. We are told that Corinth, Miss., is well fortified by the rebels. We will occupy that place soon, and as soon as we get it we will march down to New Orleans. We will stair to whip the rebels cut of Corinth to-morrow; if not to-day. We will soon starve out the rebellion. If the rebels are not brave enough to come out and fight us, so we can whip them out, we will starve them out. Oh, sister, the peach blossoms looks so fine, and if we do not whip out the rebellion soon, we will eat same fine peaches. I have just received marching orders. So good bye. I will not have any time to mail this letter here, so I will mail it at the first post-office I come to.
