XXIII Reserve Corps (German Empire)

The XXIII Reserve Corps (German: XXIII. Reserve-Korps) was a reserve corps of the German Army during World War I. It was formed in August 1914 as part of the mobilization of the German Army at the outbreak of the war.

Initially, the Corps consisted of the 45th and 46th Reserve Divisions. Throughout the war, the composition of the Corps changed as divisions were transferred in and out depending on operational needs.

The XXIII Reserve Corps saw action on both the Western and Eastern Fronts. It participated in the initial German advance through Belgium and France in 1914. Later, it was transferred to the Eastern Front, where it fought against the Russian Army. It participated in battles and offensives on the Eastern Front before eventually returning to the Western Front.

Notable battles and operations in which the XXIII Reserve Corps participated included the First Battle of Ypres, various battles on the Eastern Front, and defensive actions on the Western Front during the later years of the war.

Like other units of the Imperial German Army, the XXIII Reserve Corps was disbanded after the Armistice in November 1918.
