Of the single operating columns the news is that Sigel

has been defeated at Newmarket, in the Shenandoah Valley, by the South- ern General Breckinridge, and forced to retire to Strasburg, a town some twenty miles north, so that for the present he can give no aid to Grant. The Northern Generals Butler and Smith are operating on the James River, at Turkey Bend, where M'Clellan's army encamped so long after its great disasters in the peninsula, against Fort Darling, i. e., within ten miles of Richmond, against Confederate troops under General Beauregard. They have had much fighting, and not yet succeeded in any important ope- ration, but are useful, of course, in diverting aid from Gen. Lee.
