JANUARY 27TH.—The Secretary of War has issued such a peremptory order to Gen. Wise, that the latter has no alternative but to attempt the defense of Roanoke Island with 3000 men against 15,000 and a fleet of gun-boats. The general is quite sick, but he will fight. His son, Capt. O. Jennings Wise, who has been under fire many times already, commands a company on the island. He will deserve promotion. The government seems to have proscribed the great men of the past and their families, as if this government was the property of the few men who happen to wield power at the present moment. Arrogance and presumption in the South must, sooner or later, have a fall. The great men who were the leaders of this revolution may be ignored, but they cannot be kept down by the smaller fry who aspire to wield the destinies of a great and patriotic people. Smith and Lovell, New York politicians and Street Commissioners, have been made major-generals, while Wise and Breckinridge are brigadiers.
