The Michigan Brigade, sometimes called the Wolverines, the Michigan Cavalry Brigade or Custer's Brigade, was a brigade of cavalry in the volunteer Union Army during the later half of the American Civil War. Composed primarily of the 1st Michigan Cavalry, 5th Michigan Cavalry, 6th Michigan Cavalry and 7th Michigan Cavalry, the Michigan Brigade fought in every major campaign of the Army of the Potomac from the Battle of Gettysburg in July 1863 to the Confederate surrender at Appomattox Court House in April 1865.
The brigade first gained fame during the Gettysburg Campaign under the command of youthful Brigadier General George Armstrong Custer. After the war, several men associated with the brigade joined the 7th U.S. Cavalry Regiment and later fought again under Custer in the Old West frontier.
