Career
Hartlieb-Walsporn commanded the 5th Panzer Brigade in the early fall of 1939, then took charge of the 5th Panzer Division on 8 October 1939. By May 28, he was in reserve. Later in 1940, he was given command of the 179th Division, but in January 1942 he was again relegated to reserve or administrative posts and never again commanded front-line troops.
Wounded on 19 May 1942, Hartlieb-Walsporn was hospitalized for almost five months and spent several more months in reserve before accepting other administrative posts over the remainder of the war.
After the war ended, he was captured as a prisoner of war and imprisoned for two years.
