1. Always In The Middle Of The Battle: Edward Kiniry and the 1st Illinois Light Artillery Battery D by David Edward Wall (Xlibris, 2011).
Wall explores the battery's Civil War service through the writings of Kiniry and others. In addition to the narrative, the volume is well stocked with maps and the author also provides a battery roster and OB info for the unit at appropriate intervals.
2. Second Manassas: Longstreet's Attack and the Struggle for Chinn Ridge by Scott C. Patchan (Potomac Books, 2011).
As John Hennessy writes in the introduction, this book offers more detail and understanding of Chinn Ridge related events than those found in Hennessy's classic Return to Bull Run.
