The 9th Division (9. Division) was a unit of the Prussian/German Army.[1] It was formed in Glogau (now Głogów, Poland) in November 1816 as a brigade, became the 10th Division on September 5, 1818, and was renumbered the 9th Division on February 28, 1820.[2] The division was subordinated in peacetime to the V Army Corps (V. 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 the Province of Silesia, primarily in Lower Silesia.

Combat chronicle

The division fought in the Austro-Prussian War in 1866, including the Battle of Königgrätz.[4] In the Franco-Prussian War of 1870–71, the division saw action in the opening battles of Weissenburg and Wörth, in the Battle of Sedan, and in the Siege of Paris.[5]

In World War I, the division served on the Western Front. It initially occupied the Woëvre region of France and later fought in the Verdun in 1916. In 1918, it participated in the German spring offensive, seeing action in the Third Battle of the Aisne and the Second Battle of the Marne. Allied intelligence rated it a first class division.[6][7]

Order of battle in the Franco-Prussian War

During wartime, the 9th Division, like other regular German divisions, was redesignated an infantry division. The organization of the 9th Infantry Division in 1870 at the beginning of the Franco-Prussian War was as follows:[8]

Pre-World War I organization

German divisions underwent various organizational changes after the Franco-Prussian War. The 9th Division lost all of its original infantry regiments to other divisions and received replacement regiments. The organization of the 9th Division in 1914, shortly before the outbreak of World War I, was as follows:[9]

Order of battle on mobilization

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in August 1914 at the beginning of World War I, most divisional cavalry, including brigade headquarters, was withdrawn to form cavalry divisions or split up among divisions as reconnaissance units.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 9th Division was again renamed the 9th Infantry Division. Its initial wartime organization was as follows:[10]

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 9th Infantry Division's order of battle on March 11, 1918, was as follows:[10]
