The regiment that never ran

To destroy Confederate infrastructure, avenge the horrors of slavery, and shorten the war, the 45th Illinois Volunteer Infantry imposed the pillaging of hard-war philosophy upon Confederate lands. This comprehensive and engaging narrative explores the Civil War ordeals and triumphs of the “Lead Mine men” who hailed from eleven counties in northern Illinois. Thomas B. Mack uncovers the history on this unit of resilient midwesterners and how they brought hard-war to the Confederacy in 1862, earlier than other historians have previously suggested. 

During their service the regiment compiled an exceptional record. The 45th fought under General Ulysses S. Grant in the war’s western theater, earning honors at Vicksburg and in Tennessee. The men later reenlisted as veterans and served in General William T. Sherman’s Atlanta, Savannah, and Carolina campaigns. Mack considers the soldiers’ community, discipline, and faith in Providence during their service in the Union Army of the Tennessee and how, despite the unit’s high casualties, they upheld the lowest rate of desertion due to their fervent patriotism.

Throughout The Lead Mine Men, Mack’s focus remains on the soldiers—their extensive training in Galena and Chicago and their time in camp and in combat. He follows their experiences from recruitment to their celebratory march in the 1865 Grand Review to their postwar lives in which many struggled to adjust, receive their government pensions, and protect the unit’s legacy. In this book, Mack broadens our understanding of the Union soldiers who saved their republic and ended slavery within its borders.
