While the State Guardsmen numbered around 900, most appear to have been local volunteers, many of whom were not armed with military weapons (although many had personal civilian firearms of various types).

The battle ended around 11 a.m.[2][3] The Missouri State Guard was effectively routed from northern Boone county to Columbia.

The remainder dispersed, with Dorsey heading westward into Perche township, the northwest section of Boone County towards the Missouri River.

Mount Zion and the associated battle of Roan's Tan Yard effectively ended attempts at formal State Guard organization in Central Missouri.

While guerrilla warfare reappeared to the south and west of Columbia, Confederates did not thereafter face Union forces in conventional battle in the area until Price's Raid in the autumn of 1864.
