Serving in the Luftwaffe as the Commander of Air Region Staffs 17 (Poland), 300 (Denmark), Balkans, and Crete, Andrae took part in the campaigns against
Poland,
Denmark, the
Balkans and
Crete, respectively. In June 1941, he succeeded
Kurt Student as the Commander-in-Chief of "
Fortress Crete". Under his command, thousands of civilian residents of
Crete were tortured or executed. During 1942, SOE agent
Xan Fielding was considering a plan to capture Andrae. This plan never materialized, since in fall 1942, Andrae was assigned to the
Reich Air Ministry, leaving the command of Crete to paratrooper General
Bruno Bräuer. However, the idea of capturing a German general evolved into the
abduction of Gen. Kreipe. Andrae retired from service in May 1943, to be called again for active duty as an artillery General in April 1945 with the
4th Panzer Army. ==Post-war==
