Some interesting information found
More than 90,000 Michigan men, nearly a quarter of the state's male population in 1860, served in the war.[2] In addition to the approximately 600 men who joined the Union Navy, Michigan raised 34 regiments of infantry volunteers, one regiment of sharpshooters, eleven cavalry regiments, one engineer regiment, and numerous small independent units.
Among the more celebrated units was the 24th Michigan Volunteer Infantry, which, as a part of the famed Iron Brigade, suffered considerable losses at the Battle of Gettysburg while defending McPherson's Ridge. George Armstrong Custer's "Michigan Wolverine" Cavalry effectively battled J.E.B. Stuart at Gettysburg on the East Cavalry Field.
Several Union generals hailed from Michigan, including: Custer, Elon J. Farnsworth, Byron Root Pierce, Orlando Metcalfe Poe, Israel Bush Richardson, and Orlando B. Willcox.
