By telegraph from Baton Rouge, La., to Lieutenant-Colonel Irwin, Assistant Adjutant-General.

SIR: I am reliably informed that there are two boats fitting up at Port Hudson to assist the Frank Webb, a rebel gunboat, in making an attack upon the Conestoga, and any other boats we may have about the mouth of the Red River. It is believed that it will require some time to make their preparations for such an expedition. The boats referred to as fitting up are the Louisville, a first-class river steamer, and the D. Bentley, an old boat of not much account.

I am, sir, very respectfully, your obedient servant,

C. GROVER,

Brigadier-General, Commanding.
