Karl was the son of the Bavarian Colonel Franz Xaver Wenninger and his wife Mathilde, née Forster.
Wenninger married Kornelie Prins on July 11, 1889 in Landshut. She was the daughter of the Vice-President of the Council for the Dutch East Indies, Ary Prins. The marriage resulted in a daughter and two sons. Like their father, both sons pursued military careers. The youngest son fell as a pilot on the Western Front in 1917 , the older son Ralph initially served in the Imperial German Navy as a submarine commander and achieved the rank of Luftwaffe General in World War II. Like his father, he was awarded the Pour le Mérite order during the First World War. With the exception of princely families, this is the only case in which father and son received the highest Prussian valor award.

[1] He was then made an ensign on March 29, 1881 and promoted to second lieutenant on November 23, 1882. From October 1, 1888 to September 30, 1891, Wenninger studied at the War Academy, which qualified him for the higher adjutantage and, secondarily, for the general staff. [1] This was followed by an assignment to the equitation institute where he also received his promotion to premier lieutenant. In October he was transferred to the staff of the 2nd Cavalry Brigade in Augsburg as an adjutant. From September 24, 1895 Wenninger served on the general staff for three years, meanwhile being promoted to captain on October 28, 1897. This was followed by a year-long assignment to the staff of the I Royal Bavarian Corps before he returned to line duty as a company commander in the 5th Chevaulegers Regiment. This was followed by a tour on the staff of the 3rd Royal Bavarian Division in Landau. For two years from September 21, 1902, Wenninger worked as a teacher of military history and the history of the art of war at the War Academy, in the meantime he became a major on October 23, 1903 and then transferred again to the staff of the I Bavarian Corps. On April 19, 1906, he became a member of the study commission of the War Academy and at the same time was entrusted with the leadership of the 1st Bavarian Heavy Cavalry Regiment. Wenninger was formally appointed regimental commander on July 20, 1906; in this position promoted to Lieutenant Colonel on March 8, 1907, and to Colonel on March 7, 1909. As such he took command of the 6th Cavalry Brigade in Regensburg on September 24, 1909.

Wenninger was promoted to major general on March 7, 1912.
When World War I broke out he initially remained the Bavarian military representative as part of the Great Headquarters. In recognition of his services, Wenninger was awarded the Knight's Cross of the Order of Merit of the Bavarian Crown on September 27, 1914. Associated with this was the elevation to the personal nobility status and he was accordingly allowed to be known as "Ritter von Wenninger" after his entry in the nobility register. [2]
After his promotion to lieutenant general on September 10, 1914, Wenninger became commander of the Bavarian Cavalry Division on November 7, 1914. [3] He led the unit in the First Battle of Ypres and the subsequent trench warfare in Flanders. In March 1915, Wenninger took over command of the 3rd Royal Bavarian Division at Artois. In September and October the division was able to prevent multiple breakthrough attempts during the battles taking place near La Bassée and Arras. During the Battle of the Somme, the division defended the Martinpuich section of the Foureaux Forest. In April 1917 the division was on the Arras front south of the Scarpe. During the Battle of Arras, Wenninger succeeded in repelling three attacks by the English and stabilized his front sector.
For this achievement King Ludwig III rewarded Wenninger with the knighthood of the Military Order of Max Joseph on April 23, 1917. Shortly thereafter, Wilhelm II awarded him the Pour le Mérite on May 1, 1917. [2]
On June 5, 1917 he was appointed commander of the XVIII Reserve Corps, which at the time was in front of Verdun.
