The 7th Cavalry

In the reorganization of the U.S. army after the war Custer was assigned to the 7th Cavalry with the rank of lieutenant colonel, and he remained the acting commander of this regiment until his death. In 1867 he was court-martialed and removed from command for leaving his command at Fort Wallace, Kans., without permission, but in Sept., 1868, he was reinstated, mostly through the efforts of Sheridan, with whom he had always been a favorite. In the massacre of the Cheyenne and their allies at the battle of the Washita (Nov., 1868), he was accused of abandoning a small detachment of his men, who were annihilated. He served (1873) in Dakota Territory and in 1874 commanded the expedition into the Black Hills that led to renewed hostilities with the Sioux.
In the comprehensive campaign against the Sioux planned in 1876, Custer's regiment was detailed to the column under the commanding general, Alfred H. Terry, that marched from Bismarck to the Yellowstone River. At the mouth of the Rosebud, Terry sent Custer forward to locate the enemy while he marched on to join the column under Gen. John Gibbon. Custer came upon the warrior encampment on the Little Bighorn on June 25 and decided to attack at once. Not realizing the overwhelming numerical superiority of the Native Americans, most of whom lay concealed in ravines, he divided his regiment into three parts, sending two of them, under Major Marcus A. Reno and Capt. Frederick W. Benteen, to attack farther upstream, while he himself led the third (over 200 men) in a direct charge. Every one of them was killed in battle. Reno and Benteen were themselves kept on the defensive, and not until Terry's arrival was the extent of the tragedy known. The men (except Custer, whose remains were reinterred at West Point) were buried on the battlefield, now a national monument in Montana. Custer's spectacular death made him a popular but controversial hero, still the subject of much dispute as to his actions and character.
