Unanimity of the South.—William Howard Russell’s Diary.

December 11th.—The unanimity of the people in the South is forced on the conviction of the statesmen and people of the North, by the very success of their expeditions in Secession. They find the planters at Beaufort and elsewhere burning their cotton and crops, villages and towns deserted at their approach, hatred in every eye, and curses on women’s tongues. They meet this by a corresponding change in their own programme. The war which was made to develop and maintain Union sentiment in the South, and to enable the people to rise against a desperate faction which had enthralled them, is now to be made a crusade against slaveholders, and a war of subjugation—if need be, of extermination—against the whole of the Southern States. The Democrats will, of course, resist this barbarous and hopeless policy. There is a deputation of Irish Democrats here now, to effect a general exchange of prisoners, which is an operation calculated to give a legitimate character to the war, and is pro tanto a recognition of the Confederacy as a belligerent power.
