The War Labor Policies Board describes the necessity of recruiting women into the labor force to replace men in combat. The regulations stipulate rules for the exposure to industrial poisons, night work, employing mothers with young children and avoidance of replacing employed men. Quentin Roosevelt is killed in action flying above the Marne, and Teddy Roosevelt's son-in-law, Dr. Richard Derby is disabled by "spanish influenza."
