Colonel J. B. Walton, of the battalion Washington Artillery, having reported for duty with this command, he is announced as Chief of Artillery. He will be obeyed and respected accordingly.He [appears to have] remained in personal command of the 1st Battalion of Longstreet's Artillery, and makes no mention of any responsibility for Longstreet's remaining artillery units in his post-battle report.
By command of Major-General Longstreet.
