Custer, also known as The Legend of Custer, is a 17-episode military-western television series which ran on ABC from September 6 to December 27, 1967, with Wayne Maunder in the starring role of then Lieutenant Colonel George Armstrong Custer. During the American Civil War, Custer had risen to the rank of major general, the youngest in the Union Army. He was demoted after the war during force reductions to the rank of Captain, but was reinstated in 1866 as a Lieutenant Colonel in command of the Seventh Cavalry, stationed at Fort Riley, Kansas. Many of the soldiers in the regiment were derelicts, former Confederates, or even criminals. The series was cancelled before the script timeline would have reached the Little Big Horn River of southeastern Montana, where all perished on June 25, 1876, in a Sioux Indian ambush,Robert F. Simon played Custer's commanding officer, U.S. General Alfred H. Terry, who disapproved of Custer's long hair and much of his methodology of fighting Indians. Slim Pickens starred as a scout named California Joe Milner. Michael Dante appeared as Sioux Chief Crazy Horse. Peter Palmer played Sergeant James Bustard, a former Confederate soldier. Grant Woods appeared as Captain Myles Keogh. Read Morgan, formerly a cavalry officer on NBC's The Deputy, appeared in the episode "Spirit Woman" in the role of a medicine man.

Lt. Col. George Armstrong Custer has been reinstated and assigned to command the 7th Cavalry Regiment at Fort Hays. The regiment has become a ragtag outfit of thieves and ruffians and Custer must whip the soldiers into shape to fight, the Kiowa, Sioux and Blackfoot tribes who confront them. These tribes are being supplied shotguns by a white gunrunner and Custer and his men must rescue General Terry and the Fifth Cavalry Regiment from annihilation when they are ambushed and trapped by a large Kiowa war party.

Custer has been demoted from general and is assigned to shape up a squad of soldiers, but it's not long before he disobeys orders and goes into action; at one point, he joins forces with Crazy Horse where he gets the chance to offer the "white man" 's justifications.

General Custer is on trial for the deaths of his men at the Battle of Little Bighorn.
