Good News from the Naval Expedition.

By way of Memphis we have intelligence fully confirming the reports, via Norfolk, of the complete success of the naval expedition. The Memphis Appeal, brought from Columbus to Cairo, under the recent flag of truce, contains a special dispatch, dated Atlanta, Nov. 8th, which states that our fleet captured three forts in South Carolina, at Port Royal, Hilton Head, and Bay Point. Our forces had possession of the town of Port Royal, twenty miles of the Charleston and Savannah Railroad. The rebels admit their loss to have been very great. Forty-four of our vessels were at Port Royal, the balance having gone to the Gulf of Mexico, as the New Orleans papers speak of an immense fleet off Ship Island. It is supposed that the intention is to attack Mobile, New Orleans, and Pensacola. We landed only 10,000 men at Port Royal.

LATER. — Dispatches last night give interesting details of the expedition as forwarded to the Philadelphia Inquirer by its Fort Monroe correspondent.
