On the third day of the Battle of Gettysburg during the disastrous infantry assault nicknamed Pickett's Charge, there were two cavalry battles: one approximately three miles (5 km) to the east, in the area known today as East Cavalry Field, the other southwest of the [Big] Round Top mountain.

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 latter 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.
