German general in the Wehrmacht during World War II. He authored the first draft of the operational plan, Operation Draft East, for Operation Barbarossa, the invasion of the Soviet Union, advocating what was later known as A-A line as the goal for the Wehrmacht to achieve, within nine to seventeen weeks.
Throughout the war, Marcks commanded several division- and corps-sized units. During the Allied Normandy Invasion, as commander of the LXXXIV Corps, and having had his 53rd birthday on D-Day, he was wounded in an Allied air attack on 12 June 1944 and died the same day.
