After reviewing the strength of the two armies, Armstrong formalized the chain of command. The army was divided into four bodies. The central army, right-wing, left-wing, and reserve force. The central, left, and right consisted of 30,000 native troops. The reserve force was the 30,000 outworlders.
Armstrong commanded the central army, which consisted of 12,000 troops. Army supplies were carried within this central army. The right-wing was commanded by Ahab with 10,000 troops. While the remaining 8,000 troops of the left-wing were led by Duke Alfredo. Jack's regiment, which numbered 3,000 troops, was considered part of Duke Alfredo's left-wing army.
Hearing the arrangement, Jack offered his regiment to act as a vanguard troop.
