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. ==Order of battle on formation==
