The expanding war in Europe threatened to draw a reluctant United States into the conflict. As the potential of U.S. involvement in World War II became more evident, initial steps were taken to prepare troops what for lay ahead through "precautionary training." The division was deemed one of the most service-ready units, and Ellard A. Walsh was promoted to major general in June 1940, and then succeeded to division commander in August, following month-long command tours intended to honor senior generals Lloyd D. Ross (Iowa), George E. Leach (Minnesota), and David S. Ritchie (North Dakota) before their retirements.
