Fort Duffield — Muldraugh’s Hill, West Point, Kentucky
Fort Duffield was constructed in the autumn of 1861 as Union forces moved to secure the vital transportation routes leading into Louisville, Kentucky. The Louisville & Nashville Railroad, the Ohio River corridor, and the approaches through Muldraugh’s Hill were all vulnerable to Confederate raids and guerrilla activity. West Point, a small river town at the foot of the hill, became a staging area for troops arriving from northern states.
The fort was named for Colonel William W. Duffield of the 9th Michigan Infantry, whose regiment was among the first to arrive in West Point. Although Duffield himself was not present during construction, his regiment provided much of the labor that shaped the earthworks on the crest of the hill.
The Union Army needed a strong defensive position overlooking the river, the railroad, and the roads leading south. Confederate forces under General Buckner were active in the region, and the fall of Louisville would have been a major blow to Union control of Kentucky. Fort Duffield’s placement allowed troops to monitor the railroad bridge, the river landing, and supply routes feeding into Louisville.
The 9th Michigan Infantry arrived in late October 1861. Many of the men were young volunteers experiencing military life for the first time. They were immediately put to work cutting timber, hauling earth, and shaping the fort’s walls and parapets. Disease struck early: measles, typhoid fever, pneumonia, and dysentery spread rapidly through the camp.
Construction began almost immediately upon arrival. Soldiers felled trees, cut brush, hauled earth, and shaped the fort’s walls using picks, shovels, axes, and improvised tools. Timber was used for revetments, platforms, and interior supports, while earth formed the parapets and embankments.
The crest of Muldraugh’s Hill offered a commanding view of the Ohio River, the Louisville & Nashville Railroad, and the roads leading south. The hill was steep, rocky, and difficult to access, but its defensive advantages outweighed the challenges.
Letters from the 9th Michigan describe exhausting labor in cold, damp conditions. Despite sickness and fatigue, the work continued steadily through November. The fort’s shape followed the contours of the hill, creating an irregular but effective defensive perimeter.
By late November 1861, the fort was largely complete. Although it never saw a major battle, Fort Duffield played an important role in guarding the Louisville & Nashville Railroad and deterring Confederate activity in the region.
This timeline outlines the major events connected to Fort Duffield, the 9th Michigan Infantry, and the town of West Point during the critical early months of the Civil War.
