Includes maps. Combat Studies Institute Leavenworth Paper series, number 23. From the foreword: "Third War offers a lucid and well-researched analysis of irregular warfare during the American Civil War. Dr. Martins focus on insurgent operations in the western border region brings fresh insights to this area of study. Moreover, the history of insurgency in these western states offers a greater understanding of irregular warfare to those who may be tasked with mounting counterinsurgency operations in the not so distant future."

This work is the continuation and revision of a project started in 2006 with the publication of In Contact by the Combat Studies Institute. The original concept was to present a series of military vignettes in a style similar to the widely used case-study methodology commonly found in military literature. The final version of Between the Rivers, instead of following this strict case-study format, presents combat action vignettes as narrative accounts of the various types of actions challenging combat leaders in Iraq in 2003-2005.
