The 3rd Landwehr Division (3. Landwehr-Division) was an infantry division of the Imperial German Army during World War I. It was formed on the mobilization of the German Army in August 1914 under the "Higher Landwehr Commander 3" (Höherer Landwehr-Kommandeur 3). The Landwehr was the third category of the German Army, after the regular Army and the reserves. Thus Landwehr divisions were made up of older soldiers who had passed from the reserves, and were intended primarily for occupation and security duties rather than heavy combat. While the division was a Landwehr formation, at the beginning of the war it also had an attached Ersatz infantry brigade, made up of cadres from various regimental replacement battalions (this brigade was dissolved in September 1914). The division was primarily raised in the Prussian provinces of Posen, Lower Silesia, and West Prussia. The division was disbanded in 1919 during the demobilization of the German Army after World War I.

Combat chronicle

The 3rd Landwehr Division fought on the Eastern Front in World War I. It was on the front in Poland from the early days, and participated in the Gorlice-Tarnów Offensive, crossing the Vistula in July and advancing toward the Bug, and eventually reaching the line between the Servech and Shchara rivers, where the front stabilized. It remained in the line there until the armistice on the Eastern Front in December 1917. Thereafter, the division served in Ukraine and in the German occupation forces in Russia until late September 1918, when it went to the Western Front, serving in the Flanders area until the end of the war. Allied intelligence rated the division as fourth class and of mediocre combat value.
