The 77th Reserve Division (77. 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 XXXIX Reserve Corps. The division was disbanded in September 1918 and its assets distributed to other units. When originally formed, the division had two reserve infantry regiments from the Province of Westphalia (255th and 256th) and one from the Rhine Province (257th). The two Westphalian regiments were replaced late in the war by the 332nd Infantry Regiment, a garrison regiment from Posen with two Rhineland battalions and one Posen battalion (with a number of Poles as well as Germans), and the 419th Infantry Regiment, a thoroughly mixed unit made of companies taken from different regiments.

Combat chronicle

The 77th Reserve Division initially fought on the Eastern Front, seeing its first action in the Second Battle of the Masurian Lakes. It later fought in the Gorlice-Tarnów Offensive, including in the siege of Kovno and the battles of the Neman River, Grodno, and Vilnius. The division remained in the Courland region near Daugavpils throughout 1916 and until September 1, 1917. It then fought in the Battle of Riga and afterwards remained in positional warfare north of the Daugava River. After the armistice on the Eastern Front, the division briefly served in Livonia and Estonia, and then was transferred to the Western Front. It fought in the 1918 German Spring Offensive, seeing action in the First Battle of the Somme (1918), also called the Second Battle of the Somme (to distinguish it from the 1916 battle). After more fighting in the Somme region, the division went to the Woëvre region, between the Meuse and Moselle Rivers. The division was hit hard by the American attack on St. Mihiel, losing a large number of prisoners, and was dissolved shortly thereafter, with the remnants being distributed to other units. Allied intelligence rated the division as third class.[1][3]

  2. This wave also included the 8th Bavarian Reserve Division. 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.
