History of the 159th Regiment, N.Y.S.V

In Short

This volume serves as an intimate chronicle of the 159th Regiment, New York State Volunteers, from its formation in 1862 through the end of the Civil War in 1865. Compiled from the diary of Lieutenant Edward Duffy, the work captures the regiment’s grueling campaigns in Louisiana, the Shenandoah Valley, and the South. It documents the transformation of raw recruits into an effective fighting force, enduring the heavy losses of Port Hudson and the tactical intensity of Cedar Creek. The book remains a vital, unvarnished testimony to the reality of mid-nineteenth-century military service.

The Story

The narrative begins in late 1862, as the 159th Regiment consolidates its ranks at Camp-Kelly and prepares for deployment. After a long sea voyage from New York to the Gulf, the regiment arrives in Baton Rouge, where the reality of war replaces the initial novelty of camp life. The men face an intensive period of drilling, necessary to prepare for the looming campaign against the fortress at Port Hudson.

The regiment’s first major test arrives in April 1863 at Irish Bend, Louisiana. This maiden engagement is a harrowing initiation; the soldiers navigate rough, unfamiliar terrain and suffer significant casualties, including the loss of key officers. Following this, the regiment is thrust into the protracted investment of Port Hudson. The narrative vividly details the daily misery of the rifle pits, the failed assaults, and the relentless shelling. Victory is finally achieved in July, not through a final breakthrough, but through the strategic capitulation of the fort following the fall of Vicksburg.

The scope of the story expands as the 159th shifts its theater of operations. After months of guard and picket duty in the Lafourche District, the regiment moves to the Red River, where it navigates the complexities of the 1864 campaign, including the Battle of Mansura. The narrative then shifts to the Eastern theater, tracing the regiment’s journey to the Shenandoah Valley to join the forces under General Philip Sheridan. Here, the tempo of the war quickens. The regiment is caught in the chaotic and pivotal Battle of Cedar Creek, where the men experience the terror of a surprise attack and the subsequent, electrifying turn of fortune brought about by Sheridan’s arrival.

The final phase of the regiment’s life carries it through the Carolinas and back to Georgia, witnessing the closing days of the conflict. The news of General Lee’s surrender brings hope, yet this joy is immediately tempered by the profound national mourning following the assassination of President Lincoln. As the war draws to a close, the narrative shifts from the high-stakes friction of battle to the administrative realities of occupation duty. The record concludes in the summer of 1865, as the regiment, now seasoned and weathered, undergoes a final review in Augusta. It is a quiet end to a long, arduous journey, marking the transition of these individuals from soldiers back into the tapestry of civilian life. The book preserves the names of the fallen and the survivors, ensuring that the heavy cost paid by the 159th remains etched in the historical record of their state.

The People

Colonel Edward L. Molineux stands as the central figure of command, characterized by his energetic, ambitious approach to discipline. He is the architect of the regiment’s efficiency, leading from the front until he is severely wounded in the mouth at Irish Bend. His progression from a commander of recruits to a trusted staff officer and eventual Brevet Brigadier General represents the professional maturation of the regiment itself.

Lieutenant Edward Duffy, the compiler of the diary, serves as the observant chronicler. While he remains a modest voice, his perspective grounds the reader in the granular details of camp life and the specific, often brutal, geography of the battlefield.

Officers like Lieutenant-Colonel Draper and Adjutant Lathrop represent the heavy toll of early leadership; their deaths at Irish Bend signify the sudden, violent loss of the regiment’s initial guiding hands. Similarly, the mention of officers like Captain Richmond, who fell at Cedar Creek, highlights the ongoing attrition of the officer corps.

General Philip Sheridan appears as a transformative presence, his dramatic arrival at Cedar Creek serving as the catalyst for the regiment’s ultimate success in the valley. He acts not merely as a commander, but as a personification of the renewed vitality and determination required to see the war to its end. The soldiers themselves, often nameless in the collective, are defined by their resilience, their ability to transform from farmers and clerks into soldiers, and their collective grief for their fallen comrades.

What It's Really About

This record explores the grueling transformation of the civilian into the soldier. It asks what constitutes military effectiveness, finding the answer in the slow, repetitive labor of drill, the endurance of siege warfare, and the unwavering discipline required to survive a chaotic rout. The book is an argument for the character of the volunteer soldier, emphasizing that the victory of the Union was built upon the backs of men who learned to move, march, and fight across thousands of miles of hostile, alien terrain. Beneath the tactical accounts lies a deeper reflection on the human cost of national preservation—the constant, grinding attrition of officers and men that defined the war’s slow progress toward its ultimate, albeit somber, resolution.
