From 27 January 1907 to 21 September 1912, he was commander of the 2nd Württemberg Dragoon Regiment No. 26.[2] He was then commander of the 26th Cavalry Brigade from 21 September 1912 until 30 July 1916.[3] During World War I, he led his brigade as part of the 7th Cavalry Division.[4] On 19 September 1916, he was promoted to Generalleutnant.[5]
