World War II
World War II in Europe began on Friday, 1 September 1939, when German forces invaded Poland. Following the 1939 aerial Battle of the Heligoland Bight, Royal Air Force attacks shifted to the cover of darkness, initiating the Defence of the Reich campaign. By mid-1940, GeneralmajorJosef Kammhuber had established a night air defense system dubbed the Kammhuber Line. It consisted of a series of control sectors equipped with radars and searchlights and an associated night fighter. Each sector named a Himmelbett would direct the night fighter into visual range with target bombers. In 1941, the Luftwaffe started equipping night fighters with airborne radar such as the Lichtensteinradar. This airborne radar did not come into general use until early 1942.
Augenstein first served with 3. Staffel of Nachtjagdgeschwader 1 during mid 1942. In late 1942, Augenstein transferred to 7. Staffel. This squadron was part of III. Gruppe of NJG 1 and at the time commanded by Hauptmann Wolfgang Thimmig.

Defending against this attack, Augenstein shot down a Handley Page Halifax southwest of Raalte. Bomber Command sent 518 bombers on a mission to bomb Essen on the night of 27/28 May, 23 bombers did not retun to England. Augenstein was credited with four aerial victories thant night, including three Halifax and a Vickers Wellington bomber. The Wellington was HE752 from No. 166 Squadron which crashed near Hengelo. On 11/12 June, Bomber Command attacked Düsseldorf with 890 bombers. The RAF lost 43 aircraft that night, including a Lancaster bomber shot down by Augenstein northeast of Deventer. The following night, Bomber Command lost 24 bombers in an attack on Bochum. Augenstein was credited with the destruction of two Halifax bombers that night.
