Book excerpt: Considering the history of unconventional warfare in the United States, and specifically, during the Civil War, it begs the question: Did the Confederacy’s strategy to engage in unconventional warfare significantly contribute to its conventional strategy? Two assertions remain most accepted by historians and military personnel. The first prevailing opinion is that the Confederacy’s use of unconventional warfare was ineffective and negatively affected the overall campaign. The second opinion is that the South’s unconventional efforts yielded unparalleled success and prolonged the war. To evaluate the impact of the Confederacy’s unconventional campaign plan, the methodology of this study addresses several subordinate questions: Did the Confederacy adopt an unconventional war strategy as part of its overall strategy? How did conventional military leaders apply unconventional warfare? What effects did unconventional warfare have on conventional operations? Was unconventional warfare at the tactical level linked to operational and strategic level objectives?
