History
On mobilisation in August 1914, the 8th Army Headquarters was formed in Posen to command troops stationed in East Prussia to defend against the expected Russian attack, Plan XIX. Initially, the Army commanded the following formations:
Concerned by the defeat at Gumbinnen and the continued advance of the Russian Second Army from the south, Prittwitz ordered a retreat to the Vistula, effectively abandoning East Prussia. When he heard of this, Helmuth von Moltke, the German Army Chief of Staff, recalled Prittwitz and his deputy to Berlin. They were replaced by Paul von Hindenburg, called out of retirement, with Erich Ludendorff as his chief of staff. Under its new command, the Army was responsible for the victories at the Battles of Tannenberg and Masurian Lakes.
Dissolved and reformed
The Army of the Niemen was formed on 26 May 1915 to control the troops in Courland. The commander of the 8th Army, General der Infanterie Otto von Below, along with his Chief of Staff, Generalmajor von Böckmann, assumed command. In the meantime, the 8th Army got a deputy commander, General der Artillerie Friedrich von Scholtz, who was simultaneously commander of XX Corps. 8th Army was dissolved on 29 September 1915. On 30 December 1915 the Army of the Niemen was renamed as the 8th Army with von Below still in command.
Commanders
The original 8th Army had the following commanders from mobilisation until it was dissolved 29 September 1915.
A "new" 8th Army was formed by renaming the Army of the Niemen on 30 December 1915. It was dissolved after the end of the war on 21 January 1919.
