At twenty-eight, George Armstrong Custer was already a legend. In 1868, the Civil War hero was sent west to lead a daring winter campaign against the Cheyenne. Among the hostiles captured at the battle of Washita was Monaseetah, a ripe, raven-haired firebrand of only seventeen summers. Though "Yellow Hair," as her people called him, had taken her prisoner, it was he who was held hostage by her charms - and he who risked marriage, reputation, and career in her arms. For in love, as on any other battlefield, Custer would never know retreat.
