81st Reserve Division (German Empire)

The 81st Reserve Division (81. Reserve-Division) was a unit of the Imperial German Army in World War I. The division was formed at the end of December 1914 and organized over the next month, arriving in the line in early February 1915.[1] It was part of the second large wave of new divisions formed at the outset of World War I, which were numbered the 75th through 82nd Reserve Divisions.[2] The division was initially part of XXXXI Reserve Corps.[3] The division was disbanded in 1919 during the demobilization of the German Army after World War I. The division was recruited in various Prussian provinces: Brandenburg, Pomerania, and West Prussia.

Combat chronicle

The 81st Reserve Division initially fought on the Western Front, seeing its first action in the trenches west of the Somme. It was transferred to the Eastern Front in April 1915, and fought in the Gorlice-Tarnów Offensive, crossing the San River and fighting around Przemyśl, and then fighting in the 1915 Battle of Lemberg. It continued fighting across the border between Austro-Hungarian Galicia and Russian Poland, fighting in a series of battles leading to the taking of Brest-Litovsk in August and Pinsk in September, and then settled into positional warfare in the Pripyat Marshes. It remained there until December 1917, when, after the armistice on the Eastern Front, it was sent back to the Western Front. It fought in the trenches and saw action in the Battle of Armentières in April 1918, part of the Battle of the Lys, also known as the Lys Offensive or the Fourth Battle of Ypres. The division continued fighting on various parts of the Western Front until the end of the war. Allied intelligence rated the division as third class.[1][4]

Between the first wave (42nd through 54th Reserve Divisions and 6th Bavarian Reserve Division), several other divisions were formed on ad hoc basis, mostly taking the name of their commander or place of formation, but these were not part of a planned formal wave of new divisions.
