37th Division (German Empire)
# 37th Division (German Empire)

The 37th Division (37. Division) was a unit of the Prussian/German Army. It was formed between March 25 and April 1, 1899, in Allenstein (now Olsztyn, Poland). The division was initially subordinated in peacetime to the I Army Corps (I. Armeekorps). In 1912, it was transferred to the newly formed XX Army Corps (XX. Armeekorps). The division was disbanded in 1919 during the demobilization of the German Army after World War I. It was mainly recruited in the Prussian province of East Prussia.

Divisions received engineer companies and other support units from their higher headquarters. The 37th Division was renamed the 37th Infantry Division. Its initial wartime organization was as follows:

   * 2. Masurisches Infanterie-Regiment Nr. 147
   * 2. Ermländisches Infanterie-Regiment Nr. 151

## Combat chronicle

The 37th Infantry Division began World War I on the Eastern Front. It participated in the battles of Tannenberg and 1st Masurian Lakes. In 1915, it saw action in the Gorlice-Tarnów Offensive. The division was transferred to the Western Front in December 1916. It occupied the trenchlines in 1917, and in 1918 participated in the German spring offensive, seeing action in the Third Battle of the Aisne. In the subsequent Allied counteroffensives, the division fought in the Meuse-Argonne. Allied intelligence rated the division a first class shock division.

## Late World War I organization

Divisions underwent many changes during the war, with regiments moving from division to division, and some being destroyed and rebuilt. During the war, most divisions became triangular – one infantry brigade with three infantry regiments rather than two infantry brigades of two regiments (a "square division"). An artillery commander replaced the artillery brigade headquarters, the cavalry was further reduced, the engineer contingent was increased, and a divisional signals command was created. The 37th Infantry Division's order of battle on February 20, 1918, was as follows:

* 73.Infanterie-Brigade
   * 2. Masurisches Infanterie-Regiment Nr. 147
   * 1. Ermländisches Infanterie-Regiment Nr. 150
   * 2. Ermländisches Infanterie-Regiment Nr. 151
   * Maschinengewehr-Scharfschützen-Abteilung Nr. 57
* 3.Eskadron/Jäger-Regiment zu Pferde Nr. 10
* Artillerie-Kommandeur 37:
   * 1. Masurisches Feld-Artillerie-Regiment Nr. 73
   * II.Bataillon/Lothringisches Fußartillerie-Regiment Nr. 16
* Stab Pionier-Bataillon Nr. 134
   * 3.Kompanie/Masurisches Pionier-Bataillon Nr. 26
