In World War I, again as the 22nd Infantry Division, it fought initially on the Western Front, including in the Battle of Liège. It was soon sent to the Eastern Front, where it remained until October 1917. It fought in the First Battle of the Masurian Lakes and the Gorlice-Tarnów Offensive, as well as the Brusilov Offensive and Kerensky Offensive. After returning to the Western Front, it saw action in the 1918 German spring offensive, including the Second Battle of the Somme and the Second Battle of the Marne. Allied intelligence noted that the division had good morale, but in 1918 rated it third class, albeit better on the defensive.
