The Creek Nation Army was established by the Creek Nation in 1915, during the Great War. At its height, the Creek Nation Army comprised two regiments. Most its officers were white Confederate troops, made up of Hiram Lincoln's cavalry, who were given the task turning various civilians into real soldiers. Generally, Lincoln's men were successful in this task. However, the Creek Nation Army was effectively annihilated when it attempted to retake Beggs, Sequoyah from the United States Army.
