The Early Morning of War: Bull Run, 1861 by Edward G. Longacre (Univ of Okla Pr, 2014).
I am quite close to giddy at finally having my hands on the first micro-treatment of First Bull Run. The narrative part runs at just over 500 pages and with Blackburn's Ford not coming into the picture until around pg. 250 it really is a campaign history. Longacre has clearly done his homework on this one, with the manuscript section alone comprising over 20 densely packed pages of unpublished civilian and military primary sources. I am sure Harry will have a fine time picking his way through it. For a study this detailed, it's a shame that the maps are so few in number, especially for the confused, piecemeal back and forth exchanges around Henry Hill.
The author interview accompanying the press package hints at some of Longacre's unconventional conclusions. His reading of civilian letters leaves him convinced that home front morale was already falling before the campaign was even fought, and this in turn impacted military morale to a degree not previously understood. Longacre's findings also led him to question whether Joe Johnston's use of rail movement to reach the Manassas battlefield was truly an essential element in the Confederate victory. In another take on the "There stands Jackson like a stone wall!" controversy, the author promises a fresh look into the matter at an unprecedented level of detail. Suffice it to say that those adhering to the view that Bee intended a negative connotation will find a friend in Longacre.
