162nd, 163rd, and 164th Ambulance Companies and field Hospitals (former 1st Idaho Field Hospital, 1st Washington Field Hospital, Companies F, G, I, K, L, and M, 2nd North Dakota Infantry, detachment from 2nd Idaho Infantry, 3 officers from 3rd Wyoming Infantry, and 1 man from 4th South Dakota Infantry) In France the 41st Division received a major disappointment when it was designated a replacement division and did not go into combat as a unit. The majority of its infantry personnel went to the 1st, 2nd, 32nd and 42nd Infantry Divisions where they served throughout the war. The 147th Artillery Regiment was attached to the 32nd Division and saw action at the Third Battle of the Aisne, the Meuse-Argonne Offensive and other areas. The 146th and 148th of the 66th Field Artillery Brigade were attached as corps artillery units and participated in the battles of Château-Thierry, Aisne-Marne, Saint-Mihiel and Meuse-Argonne Offensive.

The 41st Division's mission was accomplished by a night crossing of the river. The 41st Division's annual summer camp at Fort Lewis in June and July 1940 was extended from two weeks to three, and on 16 September 1940 with President Franklin D. Roosevelt's signing of the Selective Training and Service Act of 1940, the 41st Division was inducted into federal service for one year. By this time, a National Guard recruiting campaign had raised the strength of the division to 14,000 – still well short of its war establishment strength of 18,500. The difference was made up by 7,000 selective service men, the first
