Tuesday, 18th—General Sherman went out to the front on the cars, and the two generals agreed upon the terms for the surrender of Johnston’s army. Both armies are to go into camp and remain until the terms of surrender have been approved by the War Department at Washington. The Union army is to go into camp in the vicinity of Raleigh, and the rebel army in the vicinity of Chapel Hill. I came in from picket this morning, having been out on the picket line for twenty-four hours.
