“His Excellency President Davis.

“Gen. Beauregard has been ordered to make arrangements to defend the railroad in North Carolina against Stoneman. Generals Echols and Martin are directed to co-operate, and obey his orders. R. E. Lee.”

A rumor (perhaps a 1st of April rumor) is current that a treaty has been signed between the Confederate States Government and Maximilian.

April 2d.—Bright and beautiful. The tocsin was sounded this morning at daybreak, and the militia ordered to the fortifications, to relieve some regiments of Longstreet’s corps, posted on this side of the river. These latter were hurried off to Petersburg, where a battle is impending, I suppose, if not in progress.

A street rumor says there was bloody fighting yesterday a little beyond Petersburg, near the South Side Road, in which Gen. Pickett’s division met with fearful loss, being engaged with superior numbers. It is said the enemy’s line of intrenchments was carried once or twice, but was retaken, and remained in their hands.

I hear nothing of all this at the department; but the absence of dispatches there is now interpreted as bad news! Certain it is, the marching of veteran troops from the defenses of Richmond, and replacing them hurriedly with militia, can only indicate an emergency of alarming importance. A decisive struggle is probably at hand—and may possibly be in progress while I write. Or there may be nothing in it—more than a precautionary concentration to preserve our communications.

Mrs. Davis sold nearly all her movables—including presents—before leaving the city. She sent them to different stores.

An intense excitement prevails, at 2 p.m. It pervaded the churches. Dr. Hoge intermitted his services. Gen. Cooper and the President left their respective churches, St. James’s and St. Paul’s. Dr. Minnegerode, before dismissing his congregation, gave notice that Gen. Ewell desired the local forces to assemble at 3 p.m.—and afternoon services will not be held. The excited women in this neighborhood say they have learned the city is to be evacuated to-night.

No doubt our army sustained a serious blow yesterday; and Gen. Lee may not have troops sufficient to defend both the city and the Danville Road at the same time.

It is true! The enemy have broken through our lines and attained the South Side Road. Gen. Lee has dispatched the Secretary to have everything in readiness to evacuate the city to-night. The President told a lady that Lieut.-Gen. Hardee was only twelve miles distant, and might get up in time to save the day. But then Sherman must be in his rear. There is no wild excitement—yet. Gen. Kemper was at the department looking for Gen. Ewell, and told me he could find no one to apply to for orders. The banks will move to-night. Eight trains are provided for the transportation of the archives, etc. No provision for civil employees and their families.
