Also since these were "adoption" dates, the troops probably weren't supplied that very day with new corps badges, unless they had been wearing them "unofficially.' I have seen quite a number of Corps badges at pre 1863 events.
Also from the same book:
"The Union Army eventually fielded 25 corps, each designated with a roman numeral, i.e., IX Corps. On 21 March 1863 each member of a corps in the Army of the Potomac was assigned a unique insignia to wear on his cap, front or side or left breast so that he could be identified easily on the battlefield. the practice spread until by the end of the war most Union corps had some unique insignia. These cloth or metal badges were generally red for the first division, white for the second division and blue for the third division. Corps with added divisions used green for the fourth and orange for the fifth divisions."
