With the formation of the III Royal Bavarian Corps in 1900, it was made responsible for Swabia and most of Upper and Lower Bavaria.

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.

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.

It was still in existence at the end of the war[10] in the 18th Army, Heeresgruppe Deutscher Kronprinz on the Western Front.
