I Royal Bavarian Corps

The I Royal Bavarian Corps (along with the II Royal Bavarian Corps) participated in the Franco-Prussian War as part of the 3rd Army.

It initially fought in the battles of Worth, Beaumont and Bazeilles, where it lost about 7,000 men, it also fought at the decisive battle of Sedan. After Sedan, the Corps was responsible for the removal of prisoners and ensuring transport of the booty. Thereafter, it moved south of Paris to the Loire, to shield the army during the Siege of Paris. A newly formed French Corps gathered in the Orléans area, so the Corps was reinforced by the 17th Division, 22nd Division and two cavalry divisions. After the Battle of Artenay, Orléans was captured and the reinforcing divisions were removed so the Corps did not have them for the first battles against the Army of the Loire. As a result of the subsequent Battle of Coulmiers, Orléans was lost once again.

In the period from October to late December 1870, the Corps was on service without interruption, particularly from the beginning of November in the battles of Villepion, Loigny, Orléans and Beaugency, usually against a numerically superior enemy. The losses in December alone amounted to 5,600 men. A planned return to the siege army at Paris had to be postponed several times because the Bavarians could not be spared.

The 25 peacetime Corps of the German Army (Guards, I - XXI, I - III Bavarian) had a reasonably standardised organisation. Each consisted of two divisions with usually two infantry brigades, one field artillery brigade and a cavalry brigade each.{{harvnb|Haythornthwaite|1996|pp=193–194}} Each brigade normally consisted of two regiments of the appropriate type, so each Corps normally commanded 8 infantry, 4 field artillery and 4 cavalry regiments. There were exceptions to this rule:

:V, VI, VII, IX and XIV Corps each had a 5th infantry brigade (so 10 infantry regiments)

:II, XIII, XVIII and XXI Corps had a 9th infantry regiment

:I, VI and XVI Corps had a 3rd cavalry brigade (so 6 cavalry regiments)

:the Guards Corps had 11 infantry regiments (in 5 brigades) and 8 cavalry regiments (in 4 brigades).They formed the Guards Cavalry Division, the only peacetime cavalry division in the German Army.

Each Corps also directly controlled a number of other units. This could include one or more

:Foot Artillery Regiment

:Jäger Battalion

:Pioneer Battalion

:Train Battalion

On mobilization, on 2 August 1914, the Corps was restructured. 1st Cavalry Brigade was withdrawn to form part of the Bavarian Cavalry Division{{harvnb|Cron|2002|p=301}} and the 2nd Cavalry Brigade was broken up and its regiments assigned to the divisions as reconnaissance units. Divisions received engineer companies and other support units from the Corps headquarters. In summary, I Bavarian Corps mobilised with 25 infantry battalions, 8 machine gun companies (48 machine guns), 8 cavalry squadrons, 24 field artillery batteries (144 guns), 4 heavy artillery batteries (16 guns), 3 pioneer companies and an aviation detachment.

On mobilisation, I Royal Bavarian Corps was assigned to the predominantly Bavarian 6th Army forming part of the left wing of the forces for the Schlieffen Plan offensive in August 1914. It was still in existence at the end of the war{{harvnb|Cron|2002|pp=88–89}} in the 18th Army, Heeresgruppe Deutscher Kronprinz on the Western Front.{{harvnb|Ellis|Cox|1993|pp=186–187}}
