General Alfred Terry Back marked E& HT Anthony Brady’s National Portrait Gallery, NY. Terry was the commander of the U.S. Army column marching westward into the Montana Territory during what is now popularly known as the Centennial Campaign of 1876–77. Two other columns marched toward the same objective area (George Crook's from the south and John Gibbon's from the west). A column of troops under his command arrived shortly after the Battle of Little Bighorn and discovered the bodies of Custer's men. His aide-de-camp, Robert Patterson Hughes, who was also his brother-in-law, investigated Custer's activities before and during the battle and authored a critical report. In October 1877, he went to Canada to negotiate with Sitting Bull. He was still in command in Montana during the Nez Perce War and sent reinforcements to intercept Chief Joseph.
