Soldato blu is also called as Soldier Blue, Soldat bleu, Wiegenlied vom Totschlag, Verinen sotilas, Soldat blau, Soldado Azul, Niebieski zolnierz, Cuando es preciso ser hombre。

After a cavalry group is massacred by the Cheyenne, only two survivors remain: Honus, a naive private devoted to his duty, and Cresta, a young woman who had lived with the Cheyenne two years and whose sympathies lie more with them than with the US government. Together, they must try to reach the cavalry's main base camp. As they travel onward, Honus is torn between his growing affection for Cresta, and his disgust for her anti-American beliefs. They reach the cavalry campsite on the eve of an attack on a Cheyenne village, where Honus will learn which side has really been telling him the truth.

Soldato blu actors and actresses include Candice Bergen, Donald Pleasence。
