Helmut Johannes Siegfried Lent (; 13 June 1918 – 7 October 1944) was a German night-fighter ace in World War II. Lent shot down 110 aircraft, 102 of them at night.For a list of Luftwaffe night fighter aces see List of German World War II night fighter aces Born into a devoutly religious family, he showed an early passion for glider flying; against his father's wishes, he joined the Luftwaffe in 1936. After completing his training, he was assigned to the 1. Squadron, or Staffel, of Zerstörergeschwader 76 (ZG 76), a wing flying the Messerschmitt Bf 110 twin-engine heavy fighter. Lent claimed his first aerial victories at the outset of World War II in the invasion of Poland and over the North Sea. During the invasion of Norway he flew ground support missions before he was transferred to the newly established Nachtjagdgeschwader 1 (NJG 1), a night-fighter wing.See Organization of the Luftwaffe during World War II for an explanation of the Luftwaffe structure.

Lent claimed his first nocturnal victory on 12 May 1941 and on 30 August 1941 was awarded the Knight's Cross of the Iron Cross for 22 victories. His steady accumulation of aerial victories resulted in regular promotions and awards. On the night of 15 June 1944, Major Lent was the first night fighter pilot to claim 100 nocturnal aerial victories, a feat which earned him the Knight's Cross of the Iron Cross with Oak Leaves, Swords and Diamonds on 31 July 1944.

On 5 October 1944, Lent flew a Junkers Ju 88 on a routine transit flight from Stade to Nordborchen, south of Paderborn. On the landing approach one of the engines cut out and the aircraft collided with power lines. All four members of the crew were fatally wounded. Three men died shortly after the crash and Lent succumbed to his injuries two days later on 7 October 1944.

Childhood, education and early career Lent was born on 13 June 1918 in Pyrehne, district of Landsberg an der Warthe, then in the Province of Brandenburg within the German Empire, now Pyrzany, Lubusz Province, western Poland, and christened Helmut Johannes Siegfried Lent. He was the fifth child of Johannes Lent, a Lutheran minister and Marie Elisabeth, née Braune. Helmut Lent had two older brothers, Werner and Joachim, and two older sisters, Käthe and Ursula. His family was deeply religious; in addition to his father, both of his brothers and both grandfathers were also Lutheran ministers.

From Easter 1924 until Easter 1928, Lent attended the local public primary school at Pyrehne. His father and oldest brother Werner then tutored him at home in preparation for the entrance examination at the public secondary school at Landsberg. In February 1933, Helmut joined the Jungvolk, the junior branch of the Hitler Youth. From March 1933, he acted as a youth platoon leader, or Jungzugführer (1 March 1933 – 1 April 1935) and flag-bearer, or Fähnleinführer (1 April 1935 – 9 November 1935) until he left the Jungvolk to prepare for his diploma examination. Helmut passed his graduation examinations at the age of seventeen on 12 December 1935. On 2 February 1936, he began the eight-week compulsory National Labor Service (Reichsarbeitsdienst) at Mohrin. He joined the military service in the Luftwaffe as a Fahnenjunker on 1 April 1936, against the wishes of his father.

His military training began on 6 April 1936 at the 2nd Air Warfare School (Luftkriegsschule 2) at Gatow, on the south-western outskirts of Berlin. He swore the National Socialist oath of allegiance on 21 April 1936. Flight training began on Monday, 7 August 1936 at Gatow. His first flight was in a Heinkel He 72 Kadet D-EYZA single engine biplane. Lent logged his first solo flight on 15 September 1936 in a Focke-Wulf Fw 44 Stieglitz. By this time, Lent had accumulated 63 flights in his logbook. In conjunction with flight training, the students also learned to drive motorcycles and cars and during one of these training exercises, Lent was involved in a road accident, breaking his upper leg badly enough to prevent him from flying for five months. This did not adversely affect his classroom training and on 1 April 1937, after taking his commission examination, he was promoted to Fähnrich. On 19 October 1937 Lent completed his flight training and was awarded the A/B License. He earned his wings on 15 November 1937. On 1 February 1938, he was promoted to Oberfähnrich (first ensign), and on 1 March 1938 to Leutnant. By this time, he had made 434 flights in eight different types of aircraft and had accumulated 112 hours and 48 minutes flying time, mostly in daylight flights, in single engine training aircraft.

After leaving Gatow, Helmut Lent was posted to the Heavy Bomber Crew School, or Große Kampffliegerschule at Tutow, in northeast Germany. He spent three months training as an observer (1 March 1938 – 30 May 1938). Prior to completing this course, Lent was run over by a car, resulting in a broken lower jaw, concussion, and internal bleeding. On 1 July 1938, Lent was posted to the 3rd Group of Jagdgeschwader 132 "Richthofen" (III./JG 132), flying on 19 July 1938 for the first time after his injuries.

At the beginning of September, Lent's squadron, 7./JG 132, relocated to Großenhain near Dresden, in preparation and support of the annexation of Czechoslovakia. Lent flew a number of operational patrols in this conflict until his Staffel relocated again to Rangsdorf on 29 September 1938. After the tension over the occupation of the Sudeten territories eased, Lent's unit began a conversion to the Messerschmitt Bf 108 Taifun. On 1 November 1938 III./JG 132 moved to Fürstenwalde, between Berlin and Frankfurt an der Oder, and was renamed II./JG 141, and Lent was posted to the 6th Squadron.

II./JG 141 changed its designation to I./Zerstörergeschwader 76 (I./ZG 76) on 1 May 1939 at the same time relocating to an airfield at Olomouc, Czechoslovakia. The group was being re-equipped with the Messerschmitt Bf 110, and Lent made his first flight in the Bf 110 on 7 June 1939. Lent was granted his Luftwaffe Advanced Pilot's Certificate (Erweiterter Luftwaffen-Flugzeugführerschein), also known as 'C'-Certificate, confirming proficiency on multi-engine aircraft, on 12 May 1939. While converting to the Bf 110, Lent did not have a regular wireless operator (Funker) in the rear gunner's seat, but on 14 August 1939 he was accompanied in M8+AH for the first time by Gefreiter Walter Kubisch. During the prelude of World War II on 25 August 1939 I./ZG 76 deployed to an airfield at Ohlau to the southeast of Breslau.

World War II World War II began at 04:45 on Friday 1 September 1939 when German forces crossed the Polish border. Helmut Lent, flying a Bf 110 marked M8-DH, took off from Ohlau, at 04:44 to escort Heinkel He 111 bombers on a mission over Kraków.

Invasion of Poland

The German plans for the invasion of Poland were conceived under the codename Fall Weiss (Case White). This operation called for simultaneous attacks on Poland from three directions, the north, the west and the south, beginning at 04:45 on the early morning of 1 September 1939. On this morning Helmut Lent, with Kubisch as his wireless operator and rear gunner, escorted a formation of Heinkel 111 bombers of I. and III./Kampfgeschwader 4 (KG 4) attacking the airfields at Kraków in support of the southern prong of the German attack. At 16:30 on 2 September 1939, the second day of the German attack, Lent took off in the direction of Łódź and claimed his first aerial-victory of the war, shooting down a PZL P.11.

At this point of the campaign the Bf 110s switched from bomber escort to ground-attack since the Polish Air Force was all but defeated. In this capacity Lent and Kubisch destroyed a twin-engined monoplane on the ground on 5 September and another aircraft, a PZL P.24, on 9 September. On 12 September 1939 he was attacked by a Polish aircraft which shot out his starboard engine. Lent made a forced landing behind German lines. He flew five more missions during the Polish campaign, destroying one anti-aircraft battery. For his actions in the Polish campaign Lent was awarded one of the first Iron Cross 2nd Class () of World War II on 21 September 1939. I./ZG 76 relocated to the Stuttgart area on 29 September 1939 to defend the western border against the French and British, who had been at war with Germany since 3 September 1939. From early October to middle December I./ZG 76 operated from a number of airfields in the Stuttgart and Ruhr areas before relocating north to Jever on 16 December 1939.

Battle of the Heligoland Bight

During the first month of the war the Royal Air Force (RAF) mostly focused its bomber attacks against anti-shipping operations on the German Bight. RAF bombers mounted a heavy attack against shipping off Wilhelmshaven on 18 December 1939 in what became known as the Battle of the Heligoland Bight. Twenty-four twin-engine Vickers Wellington from No. 9 Squadron, No. 37 Squadron and No. 149 Squadron formed up over Norfolk heading for the island of Heligoland. Two aircraft aborted the mission due to mechanical defects, but the remaining 22 pursued the attack and were spotted by a Freya radar on the East Frisian Islands.

Helmut Lent was ordered to intercept and engage the attacking bomber force and after refuelling—Lent had just landed at Jever from an armed patrol—claimed three Wellingtons, two of which, shot down at 14:30 and 14:45, were later confirmed. The two aircraft were both from No. 37 Squadron, captained by Flying Officer P.A. Wimberley and Flying Officer O.J.T. Lewis respectively, and both crashed in the shallow sea off Borkum. It is likely that his third claim may have been No. 37 Squadron Wellington 1A N2396, LF-J, piloted by Sergeant H. Ruse, which crash-landed on the sand dunes of Borkum. Lent was refused the victory over Wimberley, as the Wellington was attacked by Lent after it had already been badly damaged and was about to crash. The Wellington was credited to pilot Carl-August Schumacher.

His success as a fighter pilot over the North Sea had made him a minor national hero. Exploits such as those at Heligoland made good news stories for German propaganda machine. Consequently, he attracted fan mail—mainly from young girls and women—among them Elisabeth Petersen. Lent replied to her letter, and he and Elisabeth met on a blind date at the Reichshof hotel in Hamburg, after which they enjoyed a skiing holiday in Hirschegg in February 1940.

Norwegian Campaign and Battle of Britain

On 8 April 1940 eight aircraft of 1./ZG 76, under the command of Staffelkapitän Werner Hansen, deployed northward from Jever to Westerland on Sylt in preparation for operation Weserübung, the invasion of Norway. The German plan for the attack called for an amphibious assault on the Norwegian capital, Oslo, and six major ports from Kristiansand in the south to Narvik in the north. Simultaneously, Junkers 52 (Ju 52) transport aircraft would drop parachute troops to secure Oslo's Fornebu airport. Additional Ju 52s were scheduled to arrive at Fornebu twenty minutes after the parachute drop, by which time the airfield had to be in German hands. 1./ZG 76 was to provide air cover and ground-attack support for both waves. Eight Bf 110 Zerstörer of 1./ZG 76 took off at 7:00 in the morning, planning to synchronise their arrival at Fornebu with the parachute drop at 8:45. The distance from Westerland to Fornebu meant that this was a one-way operation; the Bf 110s could not hold enough fuel for the return trip. Their fuel was calculated to provide them 20 minutes flying time over Fornebu, and the pilots would have to land at Fornebu once the airfield had been seized.
