April 6th.—It seems that it was a mistake about the enemy’s monitors approaching the forts in Charleston harbor; but the government has dispatches to the effect that important movements are going on, not very distant from Charleston, the precise nature of which is not yet permitted to transpire.

Generals Johnston and Bragg write that Gen. Pillow has secured ten times as many conscripts, under their orders, as the bureau in Richmond would have done. Judge Campbell, as Assistant Secretary of War, having arrested Gen. P.’s operations, Generals J. and B. predict that our army in Tennessee will begin, immediately, to diminish in numbers.

The rails of the York River Railroad are being removed to-day toward Danville, in view of securing a connection with the N. C. Central Road. It seems that the government thinks the enemy will again possess the York River Railroad, but it cannot be possible a retreat out of Virginia is meditated.

April 7th.—Nothing definite has transpired at Charleston, or if so, we have not received information of it yet.

From the West, we have accounts, from Northern papers, of the failure of the Yankee Yazoo expedition. That must have its effect.

Judge Campbell, Assistant Secretary of War, has decided in one instance (page 125, E. B. Conscript Bureau), that a paroled political prisoner, returning to the South, is not subject to conscription. This is in violation of an act of Congress, and general orders. It appears that grave judges are not all inflexibly just, and immaculately legal in their decisions. Col. Lay ordered the commandant of conscripts (Col. Shields) to give the man a protection, without any reason therefor.

It is now said large depots of provisions are being formed on the Rappahannock. This does not look like an indication of a retrograde movement on the part of Gen. Lee. Perhaps he will advance.

This afternoon dispatches were received from Charleston. Notwithstanding all the rumors relative to the hostile fleet being elsewhere, it is now certain that all the monitors, iron-clads, and transports have succeeded in passing the bar, and at the last accounts were in readiness to begin the attack. And Beauregard was prepared to receive it. To-morrow we shall have exciting intelligence. If we are to believe what we hear from South Carolinians, recently from Charleston (I do believe it), Charleston will not be taken. If the ground be taken, it will not be Charleston. If the forts fall, and our two rams be taken or destroyed, the defenders will still resist. Rifle-pits have been dug in the streets; and if driven from these, there are batteries beyond to sweep the streets, thus involving the enemy and the city in one common ruin.

April 8th.—We learn to-day that the enemy bombarded our forts at Charleston, yesterday, two hours and a half. But few of our men were injured, and the forts sustained no damage of consequence. On the other hand, several of the iron-clads and monitors of the enemy were badly crippled; one of the latter, supposed to be the Keokuk, was sunk. Since then the bombardment has not been renewed. But no doubt the enemy will make other efforts to reduce a city which is the particular object of their vengeance. Every one is on the qui vive for further news from Charleston. Success there will make Beauregard the most popular man in the Confederacy, Lee excepted.

Speculation is running wild in this city; and the highest civil and military officers are said to be engaged, directly or indirectly, in the disgraceful business of smuggling. Mr. Memminger cannot be ignorant of this; and yet these men are allowed to retain their places.
