The regiment participated in the invasion of Belgium in August 1914; in late August the Guard Reserve Corps was transferred to the eastern theater of the war and the regiment took part in fighting in Poland, Russia and then later Lithuania.

This division would become one of the German army's best, and the regiment would find itself engaged in some of the most significant battles of the war.

From November 1915 until the end of the war it fought on the western front, namely on the Somme, Arras, Flanders, and during the Spring Offensive of 1918.

In 1919, the last remaining soldiers of the regiment formed the "Detachement Maltzan", a Freikorps ready for use in the Baltic.
