The Chattanooga Campaign: With especial reference to Wisconsin's participation therein

In Short

This detailed military history chronicles the arduous Union campaigns around Chattanooga, Tennessee, during the Civil War, emphasizing the vital contributions of Wisconsin regiments and batteries. It traces the tactical movements from the preliminary maneuvers and the harrowing battle of Chickamauga through the desperate defense and ultimate storming of Missionary Ridge and Lookout Mountain. By anchoring broad strategic overviews in official reports and firsthand accounts, the work preserves the gritty reality of soldiers navigating mountainous terrain, starvation, and fierce combat, offering a clear window into western theater operations.

The Story

The narrative opens with the complex organization and preliminary movements of the Union Army of the Cumberland, commanded by General William S. Rosecrans and stationed around Murfreesboro. Pressured by impatient superiors and hampered by logistical hurdles, the army begins its cautious advance toward Tullahoma and Chattanooga through difficult terrain where local inhabitants largely sympathize with the Confederacy. Prominent staff officers like General James A. Garfield and steadfast commanders like General George H. Thomas shape early operational planning, while various Wisconsin units such as the First Cavalry, the Third Cavalry, and multiple light artillery batteries take up essential support, reconnaissance, and supply-guarding roles across the region. The initial Tullahoma maneuver secures strategic ground with minimal casualties, but it sets the stage for a much grander and deadlier confrontation as both sides maneuver for control of the vital railroad and river hub at Chattanooga.

The campaign intensifies sharply during the perilous Chickamauga Campaign in September 1863. Union divisions navigate treacherous mountain gaps, narrowly avoiding tactical traps before colliding with General Braxton Bragg’s reinforced Confederate army along the Chickamauga River. The ensuing two-day battle unfolds as a desperate, chaotic clash marked by outflanked lines and ferocious combat where veteran regiments go to pieces under unexpected rear assaults. Despite severe command miscalculations and the near-collapse of the Union right wing under heavy assaults by Confederate veterans, General Thomas stands resolute on Snodgrass Hill, organizing a steadfast defensive stand that earns him enduring military renown. The battered Union forces ultimately withdraw into Chattanooga, where they face a perilous siege, crippled supply lines, and acute starvation while Confederate forces command the surrounding heights of Lookout Mountain and Missionary Ridge.

The final movement of the campaign shifts to dramatic redemption and aggressive counter-action upon the arrival of General Ulysses S. Grant to assume overall direction, followed closely by reinforcements from General William T. Sherman's army. Overcoming severe animal starvation and weather-induced bridge delays, the Union forces execute a meticulously planned, multi-pronged assault to break the deadlock. General Hooker successfully storms Lookout Mountain in an engagement famously shrouded by fog, effectively turning the Confederate left flank. Concurrently, an astonishing, spontaneous surge carries Union soldiers straight up the steep, crumbling face of Missionary Ridge without explicit high-level orders, breaking the Confederate center and routing Bragg’s army toward Ringgold. The campaign concludes with the secure relief of Chattanooga, the safeguarding of Union communications, and the stabilization of the Western theater, leaving the Confederate forces retreating in disorder while setting the stage for the final collapse of the rebellion.

How It Unfolds

The preliminary advance The book opens by chronicling the organizational structure and initial logistical preparations of the Union Army of the Cumberland under General Rosecrans. It describes the advance from Murfreesboro through difficult southern terrain, noting the surprise of local inhabitants who expected protection from further federal invasion. Wisconsin regiments and batteries actively participate in these early maneuvers, securing minor strategic positions and guarding vital supply lines.

The maneuvering at the mountain gaps Union divisions press forward through dangerous defiles such as Dug Gap, where careful tactical withdrawals save exposed columns from perilous Confederate traps. Meanwhile, Confederate commander Braxton Bragg receives substantial reinforcements from Virginia and Mississippi, setting the stage for a major collision. The text meticulously details the troop strengths and positions of both armies on the eve of battle.

The chaos of Chickamauga The narrative details the brutal two-day battle along the Chickamauga River, capturing the confusion of veteran regiments when struck in the flank and rear. It highlights the fierce artillery duels, the heavy casualties sustained by both sides, and the specific engagements of Wisconsin units. The text emphasizes how thin Union lines faced overwhelming pressure as commanders struggled to maintain cohesion.

The stubborn stand on Snodgrass Hill Following the catastrophic breakthrough of the Union right wing, General Thomas rallies scattered fragments, brigades, and artillery to form a defensive wall. This heroic stand on Snodgrass Hill repasts wave after wave of Confederate assaults until dark. The section underscores the exceptional tactical skill displayed by Thomas and his subordinates under extreme duress.

The siege and supply crisis The narrative shifts to the beleaguered Union army trapped inside Chattanooga, facing critical supply shortages, starvation among draft animals, and Confederate bombardment from surrounding heights. General Grant arrives to implement new plans, open secure river communications, and await the vital arrival of General Sherman's troops.

The storming of the heights The book concludes with the dramatic, synchronized November battles that break the siege. General Hooker successfully clears Lookout Mountain in the fog, while an astonishing, spontaneous surge carries Union soldiers straight up Missionary Ridge. These actions rout the Confederate forces and secure permanent Union dominance in the theater.

The People

The text focuses on several key historical commanders whose distinct objectives shape the campaign. General William S. Rosecrans wants to secure Chattanooga and advance the Union cause, but he is constantly impeded by cautious delays, logistical hurdles, and the massive reinforcements flowing to the enemy. He ultimately faces the shattering of his right wing at Chickamauga and the ensuing siege of his army. General George H. Thomas wants to protect the Union lines and maintain tactical integrity; standing in his way are overwhelming Confederate assaults and outflanked positions. Through unwavering resolve on Snodgrass Hill and masterful defensive dispositions, Thomas emerges from the campaign radically elevated in the estimation of both officers and men as a symbol of military genius. General James A. Garfield serves as Rosecrans’s energetic chief of staff, desiring swift action and operational clarity despite being overly academic and nervous about delays, eventually transitioning from the field to a seat in Congress. General Braxton Bragg wants to crush the Union army and defend Confederate territory, but his efforts are continually frustrated by poor inter-officer cooperation, missed opportunities for decisive attacks, and the eventual arrival of fresh federal forces under General Ulysses S. Grant. Grant wants to break the stalemate, relieve Chattanooga, and rescue besieged troops at Knoxville; standing against him are fortified mountain heights and starving supply animals. By orchestrating synchronized assaults, Grant succeeds completely, altering the entire trajectory of the Western theater.

In Its Own Voice

Describing his operational dilemma following the Tullahoma maneuvers, Confederate General Braxton Bragg sent an official dispatch to Richmond explaining his withdrawal.

Unable to obtain a general engagement without sacrificing my communications, I have, after a series of skirmishes, withdrawn the army to this river.

Evaluating the heavy and desperate contest on the Union right during the grueling engagements at Chickamauga, Confederate General Hindman recorded a striking concession regarding his enemy.

I have never known Federal troops to fight so well.

Capturing the sheer astonishment of eyewitnesses during the dramatic November offensive, observer C. A. Dana telegraphed the War Department about the climactic assault.

The storming of the ridge by our troops was one of the greatest miracles in military history.

What It's Really About

At its core, the book explores the vital interplay between broad strategic generalship and the gritty, localized endurance of rank-and-file soldiers, with a specific focus on Wisconsin’s military contribution. It investigates how communication failures, logistical breakdowns, and regional sympathies shape the outcomes of major military campaigns. Beneath the tactical descriptions of marches and artillery exchanges lies an inquiry into human resilience under extreme duress—examining why veteran troops collapse when struck from behind, yet ordinary soldiers can achieve the seemingly impossible by charging up steep mountain ridges without orders. Ultimately, the work argues that the salvation of the Union in the West depended as much on stubborn individual steadfastness, such as that displayed by General Thomas, as it did on overarching command decisions.

Why Read It Today

Civil War enthusiasts and regional history researchers will deeply appreciate this work for its rigorous reliance on official records, battle reports, and firsthand accounts. Reading it feels like stepping directly into a nineteenth-century archive, offering a granular, unvarnished look at troop movements, casualty statistics, and organizational charts rather than a modernized narrative history. Modern readers must be prepared for the book's period-specific style, which is densely analytical, heavily administrative, and rooted in the formal military prose of 1911. The text does not shy away from the dry cataloging of regiment numbers, battery assignments, and logistical hurdles, which can occasionally slow the narrative momentum. However, what stays with you long after closing the book is the stark realization of the physical hardships endured by the Western armies—the starving draft animals, the brutal mud and mountain fog, and the raw courage of soldiers holding the line at Chickamauga. It is an honest, painstaking monument to state participation in a national conflict, rewarding patient readers with an authentic window into the agonizing mechanics of nineteenth-century warfare.
