The Battle of Mount Zion Church

The Battle of Mount Zion Church, fought on December 28, 1861, brought the Civil War directly to this community. Missouri was bitterly divided, and control of the railroad through nearby Centralia was particularly important to Union forces for moving troops and supplies. Pro-Confederate forces had been disrupting Union operations in the region, prompting Brigadier General Benjamin M. Prentiss to lead Federal troops into the area. After an initial skirmish near Hallsville on December 27, Prentiss marched from Sturgeon early the following morning toward a force commanded by Colonel Caleb Dorsey near Mount Zion Church. The National Park Service records the action at Mount Zion on December 28 and identifies the 3rd Missouri Cavalry and Birge's Western Sharpshooters among the Union units engaged.

Fighting erupted in the woods and countryside surrounding the church and became intense at close range. According to the historical accounts preserved in Mount Zion's records, soldiers fought through the timber and cemetery, at times using gravestones for cover. The church itself became a makeshift hospital where wounded men were cared for after the fighting. Contemporary Union and Confederate accounts differ significantly over the number of troops involved and the casualties suffered—a discrepancy recognized in the surviving local history. The National Park Service records 68 Union casualties—5 killed and 63 wounded—for the action.

The battle left a permanent mark on Mount Zion. Seven unidentified stones in the cemetery mark Confederate soldiers who died as a result of the fighting, according to the church's historical records. The conflict also foreshadowed the guerrilla warfare that would plague central Missouri for years. Less than two years later, on September 22, 1863, Union forces returned and burned the original Mount Zion Church, believing it had become a gathering place for Confederate bushwhackers. The congregation survived the destruction, eventually rebuilding, while the church grounds and cemetery remained enduring reminders of the war that once swept across this quiet part of Boone County.
