"The Chattanooga Campaign" examines the military operations surrounding the Battle of Chattanooga, a critical Union victory in late 1863 that opened the door for Sherman's infamous March to the Sea later that year. The book details the strategic planning, the key engagements, and the overall outcome of this campaign. A significant focus is placed on the contributions of Wisconsin's troops. It likely explores how Wisconsin units were organized, deployed, their specific roles in key battles or maneuvers during the campaign (like the Battle of Wauhatchie or the assaults on Missionary Ridge), their geographical origins, and their impact on the Union war effort. Essentially, it provides both a broad strategic analysis of the campaign and a detailed look at the Wisconsin contingent's involvement.
