The Landwehr Corps was formed on the outbreak of war in August 1914[1] as part of the mobilisation of the Army. It was initially commanded by General der InfanterieRemus von Woyrsch, who had been recalled from retirement.[2] It was still in existence at the end of the war.
On mobilisation, the Landwehr Corps was assigned to the 8th Army on the Eastern Front. Whilst the 8th Army was concentrated in East Prussia, the Landwehr Corps was detached to Upper Silesia. On 4 September 1914, it came under the command of 1st Austro-Hungarian Army.[28] Due to losses suffered by the 4th Landwehr Division in the Battle of Tarnawka (7–9 September 1914), the 11th and 51st Landwehr Infantry Regiments were reduced to a single battalion each; the 22nd and 23rd Landwehr Infantry Regiments were reduced to two battalions each.
On 14 September 1914, the Brigade Ersatz Battalions of the 21st Ersatz Infantry Brigade were dissolved and their manpower used to replace combat losses in the following battalions:
21st Brigade Ersatz Battalion absorbed into II Battalion, 51st Landwehr Infantry Regiment
22nd Brigade Ersatz Battalion absorbed into II Battalion, 11th Landwehr Infantry Regiment
23rd Brigade Ersatz Battalion absorbed into II Battalion, 51st Landwehr Infantry Regiment
24th Brigade Ersatz Battalion absorbed into II Battalion, 11th Landwehr Infantry Regiment
78th Brigade Ersatz Battalion absorbed into II Battalion, 78th Landwehr Infantry Regiment
On 25 September 1914, the Brigade Ersatz Battalions of the 17th Ersatz Infantry Brigade were likewise dissolved:
17th Brigade Ersatz Battalion absorbed into III Battalion, 23rd Landwehr Infantry Regiment
18th Brigade Ersatz Battalion absorbed into III Battalion, 51st Landwehr Infantry Regiment
19th Brigade Ersatz Battalion absorbed into III Battalion, 22nd Landwehr Infantry Regiment
20th Brigade Ersatz Battalion absorbed into III Battalion, 22nd Landwehr Infantry Regiment
77th Brigade Ersatz Battalion absorbed into III Battalion, 11th Landwehr Infantry Regiment[29]
The Landwehr Corps joined the 9th Army on 24 September 1914.[30]
