From the 16th Ohio Regiment.

Millkins Bend, La.,
30 miles above Vicksburg, Mar. 21,

Editors Advocate: We are having beautiful weather, but for comfort a little too warm. Fans are in demand, Peach, plum and cheery trees, and roses have been in bloom sometime. We have a nice camp ground here, and much more healthy than that at Young's Point. the "pay boss" has just been here, and left us a four months supply of greenbacks. We have new clothing and good rations, and the men are in fine spirits, ready for another bout. You civilians have no idea how much braver a man feels when that vacuum in his pocket-book is filled and he knows that if he should be killed the wife and little ones at home could at least have new uniforms and more rations.

After our reverse at Chickasaw Bluffs, and the unnecessary loss of so many officers and men, our troops were very much demoralized, and ready to catch at any pretext for compromise, or a cessation of hostilities. All were gloomy, but copperheads (for we have some in the army) were exultant. They tho't their hour had come, and they worked zealously to discourage the already dispirited men. But we have them marked now, and well will they be remembered. Some pounced upon the Proclamation and showed (?) wherein Abraham lacked sense and judgment (?) others showed the great blunders in the conduct of the war, and how they might have been avoided, etc. This feeling has given way to better; the Proclamation has become a fixed fact; the conduct of the war is less fraught with error, sickness is waning, and copperheads are uneasy.

Most of the copperheads with us claim allegiance to the Democratic party, yet there are some who in name are Republicans. One of the meanest, and most false letters I have seen, was written by Capt. R. W. Liggett of Millersburg of Co. B. 16th Ohio, a man who claims to be a Republican. But politics is no excuse for denouncing the government in this her hour of trial.

The meanest traitors, however, Messrs. Editors, are those at home, to cowardly to come and help to do the fighting they remain at home, watching every opportunity to sow discord among their friends in the army. If they would join the rebels in the ranks we would only consider them enemies in war, but now they are branded as traitors forever. They went into ecstacies over discouraging letters written by our boys after we were repulsed, and had them trumpeted throughout the land. Their joy surely will be short lived.

The water is washing through the cut at Lake Providence, with a velocity that promises soon to make a channel that will pass the largest boats, but I never think the course of the Mississippi will be permanently changed.

We hear heavy firing every day in the direction of Vicksburg, and Hines's Bluffs. The steam dredges have the canal in front of Vicksburg nearly ready for the passage of boats. Com. Farragut is reliably reported as lying below Warrenton, with his fleet, having passed the batteries at Port Hudson. The fall of Vicksburg is considered here as certain, and the day can not be far distant. The men are anxious for the fray. If you will take care of the rebels at home, the boys will take care of those here. The men in the army like the conscription act, and hope it will soon be carried into effect.

Hoping the sentiments of the people at home are still in favor of the Government, and the war for the Union, I sign myself

WILSCOT.
