91st Division - The Far West Division

The 91st Division was created primarily from draftees from California, Idaho, Montana, Nevada, Oregon, Utah, Washington, and Wyoming. The western origins of the division led to its nicknames the “Far West” or “Wild West” Division, and its motto: “Powder River! Let ’er Buck.”

The 91st Division was the only division to participate in the Meuse-Argonne Offensive that did not have prior combat experience. On September 25, 1918 the night before the battle, General John J. Pershing visited the division to express his confidence in its potential and to boost its morale.

Commander-in-Chief Gen. John J. Pershing discusses with Maj. Gen. William H. Johnston, 91st Division.

Pershing’s sentiments proved well-founded. Positioned between the 37th and the 35th divisions, the “boys” of the “Wild West” attacked vigorously on the morning of September 26, 1918. They broke through three German lines to a depth of eight kilometers on their first day in battle.

By September 30, 1918 they had advanced even further, and reached la Grange-aux-Bois. Here the 32nd Division relieved them on October 4, 1918. The division redeployed to participate in the Ypres-Lys Offensive, captured Audenande, and pushed on to the Scheldt River.
