From Mobile--Fort Powell blown up — shameful surrender of Port Gaines, &c.
Mobile, August 8.
--Friday night, Lieutenant-Colonel Williams, commanding Fort Powell, evacuated and blew up the fort.
Yesterday and to-day the enemy are shelling Fort Gaines.
The people of Mobile are all ready for the fray.
Great confidence prevails.
The people are satisfied with the conduct of Buchanan, Murphy and Burnett, of the navy.
[Second Dispatch.]
Mobile, August 8.
--It is painfully humiliating to announce the shameful surrender of Fort Gaines, at half- past 9, o'clock this morning, by Colonel Charles Anderson, of the Twenty-first Alabama regiment.
This powerful work was provisioned for six months and had a garrison of six hundred men. He communicated with the enemy's fleet by flag of truce without the sanction of General Page. General Page enquired by signal what his purpose was, but received no answer.
His attention was attracted by signal guns.
Page repeatedly telegraphed "hold on to year fort." The same night Page visited Fort Gaine and found Anderson on board the Yankee fleet, arranging the terms of capitulation.
He left peremptory orders for Anderson, on his return, not to surrender the fort, and relieved him of his command.
Fort Morgan signaled this morning, but no answer was received except the hoisting of the Yankee flag over the ramparts of Fort Gaines.
Anderson's conduct is officially pronounced inexplicable and shameful.
