Walter Borchers (22 January 1916 – 6 March 1945) was a German Luftwaffe military aviator and wing commander during World War II. As a flying ace, he was credited with 59 aerial victories, including 43 nocturnal victories, 10 as a destroyer pilot and 6 four-engined bombers at day time, claimed in roughly 300 combat missions. Prior to his death he held the position of wing commander of the 5th Night Fighter Wing. Biography Walter Borchers was born on 22 January 1916 in Ofen in Ammerland, Duchy of Oldenburg as the third of three brothers, all of whom would be awarded the Knight’s Cross of the Iron Cross during the course of World War II. His brother, Major Adolf Borchers received the Knight's Cross on 22 November 1944 as Staffelkapitän of 11./Jagdgeschwader 51 "Mölders". A second brother, SS-Hauptsturmführer Hermann Borchers received the Knight's Cross on 16 October 1944 as commander of the I. Battalion of the SS-Panzergrenadier-Regiment 19. Borchers was a member of the 5th Staffel (squadron) of Zerstörergeschwader 76 (ZG 76—76th Destroyer Wing) at the outbreak of World War II on 1 September 1939. He became the Staffelkapitän of 5./ZG 76 in the fall of 1940. He claimed 10 aerial victories during the Battle of France and Battle of Britain. Night fighter career Following the 1939 aerial Battle of the Heligoland Bight, RAF attacks shifted to the cover of darkness, initiating the Defence of the Reich campaign. By mid-1940, Generalmajor (Brigadier General) Josef 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 (canopy bed) 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 Lichtenstein radar. This airborne radar did not come into general use until early 1942. Borchers' Staffel was transformed to the 8. Staffel of Nachtjagdgeschwader 3 (NJG 3—3rd Night Fighter Wing) in the fall of 1941, flying night fighter missions in Defence of the Reich. Borchers claimed his first nocturnal aerial victory on the night of 3 March 1943. He claimed his 12th and 15th against the United States Army Air Forces (USAAF) heavies—four-engined strategic bombers—in 1943. Still an Oberleutnant, he was made Gruppenkommandeur of the III./Nachtjagdgeschwader 5 (NJG 5—5th Night Fighter Wing) on 22 April
