• Our People Are Warlike: Civil War Pittsburgh and Home-Front Mobilization by Allen York.
• Silent Cavalry: How Union Soldiers from Alabama Helped Sherman Burn Atlanta—And Then Got Written Out of History by Howell Raines.
• The Boy Generals: George Custer, Wesley Merritt, and the Cavalry of the Army of the Potomac, from the Gettysburg Retreat Through the Shenandoah Valley Campaign of 1864 by Adolfo Ovies.
• Thunder in the Harbor: Fort Sumter and the Civil War by Richard Hatcher.
• Southern Black Women and Their Struggle for Freedom during the Civil War and Reconstruction ed. by Karen Cook Bell.
Comments: I've been looking forward to Hatcher's Sumter book for a long time. With the author serving as the site's NPS historian for decades, the match between writer and topic should be a perfect fit.
1 - These monthly release lists are not meant to be exhaustive compilations of non-fiction releases. They do not include reprints that are not significantly revised/expanded, special editions not distributed to reviewers, and digital-only titles. Works that only tangentially address the war years are also generally excluded. Inevitably, one or more titles on this list will get a rescheduled release (and they do not get repeated later), so revisiting the past few "Coming Soon" posts is the best way to pick up stragglers.
