The division was intended to be composed of National Army draftees mainly from Maine, Vermont and New Hampshire, but in October, over 5,000 draftees, mainly from Oklahoma and Minnesota, were sent to the division at Camp Cody. Initial instruction at Camp Cody went relatively well, but the 172nd Brigade's training at Camp Jackson was delayed by a lack of personnel. Its regiments were at less than half-strength as late as the beginning of November. In late October, the 97th was struck by the 1918 flu pandemic, which sickened over 500 soldiers and killed more than 100. On 25 October, Brigadier General James R. Lindsay became division commander as Martin became its chief of staff. The war ended with the Armistice of 11 November, and the 97th was ordered to be demobilized on 20 November. At the time, it was only partially organized and consisted of 402 officers and 7,889 men. The demobilization was completed on 22 December/
