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in August 1914 at the beginning of World War I, most divisional cavalry, including brigade headquarters, was withdrawn to form cavalry divisions or split up among divisions as reconnaissance units.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 6th Division was again renamed the 6th Infantry 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. 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 6th Infantry Division's order of battle on February 16, 1918, was as follows:
12.Infanterie-Brigade:
*Infanterie-Regiment Großherzog Friedrich Franz II von Mecklenburg-Schwerin Nr. 24
*Infanterie-Regiment General-Feldmarschall Prinz Friedrich Karl von Preußen Nr. 64
*Infanterie-Regiment Nr. 396
*Machinengewehr-Scharfschützen-Abteilung Nr. 69
5.Eskadron/Husaren-Regiment von Zieten Nr. 3
Artillerie-Kommandeur 64:
*Feldartillerie-Regiment General-Feldzeugmeister Nr. 3
