The12th Division (12. Division) was a unit of thePrussian/GermanArmy.[1] It was formed in Neiße (nowNysa, Poland) on September 5, 1818.[2] The division was subordinated in peacetime to theVI Army Corps (VI. Armeekorps).[3] The division was disbanded in 1919 during the demobilization of the German Army after World War I. The division was recruited primarily in theProvince of Silesia, mainly in the region ofUpper Silesia.
InWorld War I, the division served initially on theWestern Front. It spent most of this period in various parts of the trenches and suffered heavily in the 1916Battle of the Somme. At the end of December 1916, it was sent to theEastern Front, where it did not participate in any major actions. The division returned to the Western Front in May–June 1917. At the end of September 1917, it was sent to theItalian Front, where it fought in theBattle of Caporetto. After returning to the Western Front, the division saw action in theGerman spring offensive of 1918, including theBattle of the Lys, and the subsequent Allied counteroffensives, including the 1918Battle of Cambrai.[6][7] The division was rated as a good second-class division by Allied intelligence.[6][7]
During wartime, the 12th Division, like other regular German divisions, was redesignated an infantry division. The organization of the 12th Infantry Division in 1870 at the beginning of the Franco-Prussian War was as follows:[8]
German divisions underwent various organizational changes after the Franco-Prussian War. The organization of the 12th Division in 1914, shortly before the outbreak of World War I, was as follows:[9]

Infanterie-Regiment Keith (1. Oberschlesisches) Nr. 22
3. Schlesisches Infanterie-Regiment Nr. 156
24. Infanterie-Brigade

3. Oberschlesisches Infanterie-Regiment Nr. 62
78. Infanterie-Brigade
4. Oberschlesisches Infanterie-Regiment Nr. 63

On mobilization in August 1914 at the beginning of World War I, most divisional cavalry, including brigade headquarters, was withdrawn to form cavalry divisions or split up among divisions as reconnaissance units. Divisions received engineer companies and other support units from their higher headquarters. The 12th Division was again renamed the 12th Infantry Division. Its initial wartime organization was as follows:[10]
24. Infanterie-Brigade:
Infanterie-Regiment von Winterfeldt (2. Oberschlesisches) Nr. 23
3. Oberschlesisches Infanterie-Regiment Nr. 62
78. Infanterie-Brigade:
4. Oberschlesisches Infanterie-Regiment Nr.63
4. Schlesisches Infanterie-Regiment Nr. 157
Ulanen-Regiment von Katzler (Schlesisches) Nr. 2
12. Feldartillerie-Brigade:
Feldartillerie-Regiment von Clausewitz (1. Oberschlesisches) Nr. 21
2. Oberschlesisches Feldartillerie-Regiment Nr. 57
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 becametriangular - 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 12th Infantry Division's order of battle in 1918 was as follows:[10]
24. Infanterie-Brigade:
Infanterie-Regiment von Winterfeldt (2. Oberschlesisches) Nr. 23
3. Oberschlesisches Infanterie-Regiment Nr. 62
4. Oberschlesisches Infanterie-Regiment Nr. 63
Maschinengewehr-Scharfschützen-Abteilung Nr. 20
4. Eskadron/Ulanen-Regiment von Katzler (Schlesisches) Nr. 2

^From the late 1800s, the Prussian Army was effectively the German Army, as during the period of German unification (1866-1871) the states of theGerman Empire entered into conventions with Prussia regarding their armies and only the Bavarian Army remained fully autonomous.
