It’s not much, but when A. Porter submitted Ambrose Burnside’s report, he refers to Burnside’s command as the Second Brigade, Second Division, Army of Northeastern Virginia. Series I, vol. 2, p. 395.
After a quick check of the OR’s, I responded:
As for the report of Porter: that’s Andrew Porter, First Brigade commander of Hunter’s Division who took over command of the division when Hunter was wounded. He does mention the name of the army, but this cover letter to Burnside’s report was not written until August 19, while Burnside’s report itself was sent from Hdqrs. Second Brigade, Second Division, Major [!!!] General McDowell’s Column and dated July 24. Porter’s own report on page 383 refers to the First Brigade, Second Division, of the Army. It was written on July 25. If anything, this probably supports the ex post facto origins of the Army of Northeastern Virginia.
David’s post last year about McDowell’s misspelled headstone played some role in feeding my interest in First Bull Run. Thanks for that, David, and thanks for taking the time to comment here.
