Structure on formation

On formation, in August 1914, the Landwehr Corps consisted of two divisions, which were made up of 3rd line units. The Senior Landwehr Commander 3 was formed with units drawn from V Corps District (Province of Posen and Lower Silesia) and Senior Landwehr Commander 4 was formed with units drawn from VI Corps District (Province of Silesia, particularly Upper Silesia).

Combat chronicle

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

The Landwehr Corps joined the 9th Army on 24 September 1914.^[30]
