MILWAUKEE, WIS., April 13, 1864.

Brigadier-General SIBLEY,

Saint Paul, Minn.:

You misinterpret my dispatch of the 4th. The Sixth Regiment will not leave Minnesota at all until return of Eighth Regiment from expedition, but is to be used precisely as if no orders on the subject of the regiment had ever been issued. It was useless to notify the companies about being in readiness to march.

JNO. POPE,

Major-General.

BATON ROUGE, LA., April 14, 1864.

Major JOHN LEVERING,

Assistant Adjutant-General, New Orleans, La.:

I have just received a statement that Powers, with a 2,000 volunteer party, was to assault Port Hudson this morning or to-morrow. Steamer Grey Eagle passed Port Hudson this morning; reported a battle or skirmish going on, and that there was no one to receive her mail.

P. ST. GEO. COOKE,

Brigadier-General, U. S. Army, Commanding.

HEADQUARTERS DEPARTMENT OF THE GULF, New Orleans, April 14, 1864.

Captain MAHLER,

SIR: By direction of Major-General Banks I have the honor to request that you will make ready a suitable steamer to sail to-day for Texas to carry a bearer of important dispatches to Major-General McClernand. You will please to notify me in writing by return of bearer what vessel you shall send, where she will lie, and at what hour she will be ready.

HEADQUARTERS DEFENSES OF PLAQUEMINE, Plaquemine, La., April 14, 1864.

Captain GEORGE W. DURGIN, Jr.,
Acting Assistant Adjutant-General:

SIR: I have the honor to report that a party of guerrillas have made their appearance in this neighborhood, of whose number I am at present unable to judge. They are reported in the vicinity of Indiana Village, burning cotton, &c., The want of a sufficient cavalry force is seriously felt here, and I would respectfully suggest that a company of cavalry would be of great in this place.

Very respectfully, your obedient servant,

RICHARD G. SHAW,

Major 14th Rhode Island Heavy Artg. (Colored), Commanding Post.
