• The First Battle of Manassas: An End to Innocence, July 18-21, 1861 Revised Edition by John J. Hennessy (Stackpole, 2015).
For detailed discussions of the fighting at Matthews Hill and Henry Hill on July 21, the appropriate sections of Edward Longacre's recent tome have been the closest rival to John Hennessy's 1989 classic The First Battle of Manassas. Now Hennessy had upped the ante with a revised edition that was just released about a week ago. There's no new introduction to orient readers regarding specific improvements but the maps have been redone (marginally improved, I would say) and there's around 30 pages worth of fresh text. This is a must-have for the FBR section of your home library.
