I wrote Gen. Halleck,
CITY POINT, VA., July 21, 1864-11 a. m.
Washington, D. C.:
You may retain Wright’s command until the departure of Early is assured, or other forces are collected to make its presence no longer necessary. I have ordered another regiment of heavy artillery back to Washington, but they will not go while the Sixth and part of the Nineteenth Corps are there. I am now sending back all veterans whose term of service expires previous to the 25th of August. If Early has halted about Berryville, what is there to prevent Wright and Hunter from attacking him?
