The following quotes are from an article written by F. A. Boyle, Adjutant, 32nd NC Troops, published in The Richmond Dispatch, 11 August 1895, pg. 8, col. 2-3.

The 32d N.C. Regiment.
How It Carried Its New Flag at Gettysburg.
"While [at Carlisle, PA] the General [Lee] received a sample of a new Confederate flag that had been conditionally accepted by the Congress then in session in Richmond, and forwarded by order of that body to him in order that he might pass upon its merits. It consisted simply of the Confederate battleflag, used as a "Jack," i.e. occupying the upper corner of the flag next to the staff, while its remainder was pure white."
"[General] Daniel confided it to the keeping of Colonel E. C. Brabble, commanding the Thirty-second North Carolina Regiment, and thus it was that the Thirty-second had the proud distinction of bearing into battle this beautiful emblem of a new nation."
[After returning to Virginia, near Darkesville, General Ramseur] "remarked - exactly in these words: "By the way, the finest thing that I saw during the whole battle was the conduct of that regiment that carried into the fight that flag with the long white tail to it. They marched as steadily as if on dress parade, and when commanded to retreat, marched back as steadily as ever under a most galling fire."
"Yes," said General Daniel, in the somewhat pompous way entirely natural to him, "Yes, that was one of my regiments.""
