Rebel War Clerk’s Diary.

JULY 28TH.—We have taken two prisoners in civilian’s dress, Harris and ___, on the field, who came over from Washington in quest of the remains of Col. Cameron, brother of the Yankee Secretary of War. They claim a release on the ground that they are non-combatants, but admit they were sent to the field by the Yankee Secretary. Mr. Benjamin came to the department last night with a message for Secretary Walker, on the subject. The Secretary being absent, he left it with me to deliver. It was that the prisoners were not to be liberated without the concurrence of the President. There was no danger of Secretary Walker releasing them; for I had heard him say the authorities might have obtained the remains, if they had sent a flag of truce. Disdaining to condescend thus far toward a recognition of us as belligerents, they abandoned their dead and wounded; and he, Walker, would see the prisoners, thus surreptitiously sent on the field, in a very hot place before he would sign an order for their release. I was gratified to see Mr. Benjamin so zealous in the matter.
