After recovering from an illness in the fall of 1915, Marwitz served on the Western Front as the commander of the VI Corps, before returning to the Eastern Front until the successful halting of the Russian Brusilov Offensive in June 1916. On 6 October 1916 he became adjutant to Kaiser Wilhelm II, a post that he left in December 1916 to take command of the Second Army on the Western Front.
