10th Reserve Division (German Empire)

The 10th Reserve Division (10. Reserve-Division) was a unit of the Imperial German Army in World War I. The division was formed on mobilization of the German Army in August 1914 as part of V Reserve Corps. The division was disbanded in 1919 during the demobilization of the German Army after World War I. The division was formed with a regular infantry brigade from the Province of West Prussia and a reserve infantry brigade from West Prussia and the Province of Posen.

Combat chronicle
The 10th Reserve Division fought on the Western Front, participating in the opening German offensive which led to the Allied Great Retreat. Thereafter, the division remained in the line in the Verdun region until February 1916, when it entered the Battle of Verdun. After a respite in the lines in the Upper Alsace and Champagne, the division fought in the later phases of the Battle of the Somme. It returned to Verdun in late October 1916. In 1917, it fought on the Aisne, including in the Second Battle of the Aisne, also known as the Third Battle of Champagne. The division returned again to Verdun in April 1917, remaining in the line until late July, when it went into reserve for a few weeks. It returned to the trenchlines near Reims on 8 August, remaining in that region until March 1918. The division then participated in the 1918 German Spring Offensive, including the Third Battle of the Aisne, and in the Second Battle of the Marne, the last major German offensive of the war. It fought against the French and American Aisne-Marne Offensive and remained in the line until the end of the war. Allied intelligence rated the division as first class and described it as a "big attack" division.
