9. The Battle of Carthage: Border War in Southwest Missouri, July 5, 1861
(comment: good coverage of battles and events in Missouri up to the Battle of Wilson's Creek. A nice account of the battle of Boonville is included followed by a highly detailed tactical history of the running fight at Carthage.)
8. Sabine Pass : The Confederacy's Thermopylae
7. Island No. 10 : Struggle for the Mississippi Valley
6. The Battle of Wilson’s Creek by Edwin C. Bearss
(comment: thorough, clearly written account and remains the best tactical history of the battle itself. Very nice maps.)
5. October 25th and the Battle of Mine Creek by Lumir Buresh
(comment: a great tactical history of Mine Creek and a wonderfully rich retelling of the Confederate retreat and Union pursuit after the 1864 Battle of Westport)
4. The Division: Defending Little Rock, Aug. 24th-Sept. 10th, 1863
(comment: this is a marginal inclusion to the list. Although harmed by very poor binding and printing along with a novelistic writing style that takes a lot of liberties, this book is the only detailed history of the battles surrounding the capture of Little Rock. In that respect, it is quite good. Maps, although a bit crude, are plentiful and very detailed.)
3. Embattled Arkansas by Michael Banasik
(comment: the centerpiece of this book is the Prairie Grove campaign but many chapters cover 1862 events in Missouri, including the massive recruiting campaigns, and the battles of Newtonia and Lone Jack. Extensive coverage of Union campaigns into Indian Territory is present as well.)
2. The Vicksburg Campaign 3 Vols by Edwin C. Bearss
(comment: heavy T-M coverage, both land and naval. Including great sections on Arkansas Post, the Battle of Helena, and various other attacks on Union conclaves along the west bank of the Mississippi.)
1. Pea Ridge: Civil War Campaign in the West
(comment: IMO, this is the best history of any CW battle or campaign. But then again Pea Ridge is my favorite battle to study so I am biased.)
