# 121st Infantry Division (German Empire)

The 121st Infantry Division (121. Infanterie-Division) was a formation of the Imperial German Army in World War I. The division was formed on March 25, 1915, and organized over the next several weeks. It was part of a wave of new infantry divisions formed in the spring of 1915. The division was disbanded in 1919, during the demobilization of the German Army after World War I.

The division was formed primarily from the excess infantry regiments of regular infantry divisions that were being triangularized. The 60th Infantry Regiment was formerly part of the 31st Infantry Division, the 7th Reserve Infantry Regiment came from the 9th Reserve Division, and the 56th Reserve Infantry Regiment came from the 13th Reserve Division. The division was mainly composed of Westphalians.

## Combat chronicle

The 121st Infantry Division initially fought on the Western Front in World War I, entering the line in the Woëvre region at the beginning of May 1915. It remained in that area until March 1916, fighting in the Battle of Bois-le-Prêtre. It then fought in the Battle of Verdun. It briefly fought in the Battle of the Somme until July 18 when it was transferred to the Eastern Front, where it went into the line on the Styr River until the end of the year. It then went into the line near Lake Narač until May 1917, when it returned to the Western Front. It fought in the Battle of Passchendaele in late 1917, and saw action in the Second Battle of the Marne and the Second Battle of the Somme, also known as the Third Battle of the Somme, in 1918.
