On 9 February 1915 Guards Reserve Corps was redesignated Armee-Gruppe Gallwitz. Its commander was raised to the status of an Army Commander on 18 March 1915 and his Armee-Gruppe was redesignated as 12th Army on 7 August 1915.

On 22 July, the armies of Central Powers crossed the Vistula river. In August, the Russian Fourth Army left the Ivangorod fortress. With the continuing Russian retreat, Warsaw became isolated, and the 12th Army seized the opportunity and conquered it on 4–5 August.


Armee-Gruppe Gallwitz was redesignated as 12th Army on 7 August 1915 with von Gallwitz remaining in command.[3] The 12th Army was dissolved on 9 October 1916 when its commander was transferred to 8th Army.

  • Armee-Gruppe or Army Group in the sense of a group within an Army and under its command, generally formed as a temporary measure for a specific task.
  • Heeresgruppe or Army Group in the sense of a number of armies under a single commander.
