Main article: Michigan in the American Civil War

This article provides a list of Michigan military units active during the American Civil War.^[1] As a northern state, Michigan was part of the Union, and its units were active during the entire length of the war. Units included the Michigan Brigade (known as the "Wolverines"), which served under George Armstrong Custer during the Gettysburg Campaign.^[2] Michigan was unique among the Northern States as instead of forming new units the state would send recruits to their units already in the field to be under the command of veteran officers and enlisted instead of the entire regiment being green.

George Armstrong Custer, led the Michigan Brigade, called the "Wolverines"

Gen. Alpheus S. Williams trained the first Michigan volunteer units in 1861.

As a captain in the 19th Michigan, Frank Baldwin was awarded the Medal of Honor.

Orlando B. Willcox was the first colonel of the 1st Michigan Infantry

The Michigan Soldiers and Sailors Monument in Detroit is one of many monuments to Michigan's soldiers
