123rd Infantry Division (German Empire)
The 123rd Infantry Division (123. Infanterie-Division) was a formation of the Imperial German Army in World War I. The division was formed on April 1, 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 a Royal Saxon division, made up of troops from that kingdom. It was formed primarily from the excess infantry regiments of regular infantry divisions which were being triangularized. The division's 245th Infantry Brigade was the former 64th Infantry Brigade of the 32nd (3rd Royal Saxon) Infantry Division, and came to the division with the 178th Infantry Regiment. The 106th Reserve Infantry Regiment came from the 24th (2nd Royal Saxon) Reserve Division and the 182nd Infantry Regiment came from the 23rd (1st Royal Saxon) Infantry Division. Combat chronicle

The 123rd Infantry Division initially fought on the Western Front in World War I, entering the line in the Aisne region in mid-April 1915. Later in 1915, it fought in the Battle of Loos. It remained on the front in the Flanders and Artois regions into 1916, and in July entered the Battle of the Somme, where it reportedly lost 6,000 men. It was transferred to the Eastern Front at the end of the month, where it went into the line near Lake Narač until November 1917, when it returned to the Western Front. It went into the line near Verdun until May 1918. It later fought in the Second Battle of the Marne and then returned to the line near Verdun. Late in 1918, it faced the Allied Meuse-Argonne Offensive. It remained in the line until the end of the war. Allied intelligence rated the division as third class and of mediocre combat value.
