Lambert was born on 18 February 1916 in Kleestadt in the Grand Duchy of Hesse. After he joined the Luftwaffe, he was trained as a pilot in 1937/38. Lambert then served as a flight instructor in various training units until 1943.
World War II
World War II in Europe began on Friday 1 September 1939 when German forces invaded Poland. In 1943, Lambert was transferred to II. Gruppe of Schlachtgeschwader 1. As an Oberfeldwebel, he flew his first combat mission on southern sector of the Eastern Front and claimed his first aerial victory on 23 April 1943 was not confirmed. Lambert flew almost 200 ground support missions in which he and the fellow pilots of II./SG 2 accounted for the destruction of hundreds of ground support vehicles and artillery batteries. II./SG 1 was renamed Schlachtgeschwader 2 "Immelmann" on 18 October 1943. II. Gruppe of SG 2 was heavily involved in the Crimean campaign during early-mid 1944, and in addition to its usual ground-attack work flew interception sorties, claiming some 247 Soviet aircraft shot down. On 10 April 1944, he claimed four victories, a Yak-9, a P-39 Airacobra and two Il-2 Sturmoviks. On 17 April 1944, Lambert was credited with twelve aerial victories, including five Il-2 Sturmovik. According to Bergström, this number may be exaggerated according to Soviet records. The Ministry of Aviation only holds records for five of these claims. He claimed nine further victories on 4 May. On 6 May 1944, Lambert again claimed to have become a "double-ace in a day". These 14 aerial victories over an unknown type were not documented by the RLM. Leutnant Lambert claimed some 70 aerial victories during one three-week period. He received the Knight's Cross of the Iron Cross on 14 May 1944 and the German Cross in Gold on 1 October 1944. By May 1944, the depleted II./SG 2 retired to bases in Romania. Following the Battle of the Crimea resulting in the evacuation of the Crimea by the Germans, Lambert served as an instructor with Schlachtgeschwader 151. In March 1945, he was posted to Schlachtgeschwader 77 where he commanded 8. Staffel as Staffelkapitän and Oberleutnant. In April 1945, Lambert was credited with his 100th aerial victory. He was the 101st Luftwaffe pilot to achieve the century mark. On the morning of 17 April 1945, LeutnantGerhard Bauer, Lambert, and another pilot were taking off from Kamenz for a mission to the front when American P-51Ds of the 55th Fighter Group appeared. Bauer's Fw 190 F-9 "Black 1 +" was quickly shot down north of Kuckau, about eight kilometres east-south-east of Kamenz. August Lambert and another 8./Schlachtgeschwader 77 pilot tried desperately to get away, but could not lose their pursuers. Lambert was shot down and killed in action in his Fw 190 F-8 "Black 9 +" just north of Hoyerswerda, a town some north-north-east of Kamenz. Lambert was officially credited with shooting down 116 enemy aircraft, all claimed on the Eastern Front. He also claimed over 100 vehicles destroyed in ground attacks. After his death, Lambert had been nominated for the Oak Leaves to his Knight's Cross, but this request was not approved.
