In February 1942,

Staffel (3rd squadron) of
Jagdgeschwader 53 (JG 53—53rd Fighter Wing) based in
Sicily. In March and April 1942, he flew 60 missions over
Malta. On 1 April, he was promoted to
Unteroffizier (non-commissioned officer). In May 1942, I./JG 53 was transferred to the
Eastern Front near
Kursk. Crinius achieved his first victories on 9 June when he shot down two
Il-2 Sturmoviks. On 8 July, Crinius shot down two
Douglas Boston bombers west of
Voronezh, although his aircraft was hit by Russian anti-aircraft fire and he was forced to belly-landed his
Messerschmitt Bf 109 F-4 (
Werknummer 10243—factory number) between the enemy lines, where he was rescued by a German patrol and safely returned to his unit. In July 1942, I./JG 53 was sent to the southern sector of the Eastern Front, where Crinius claimed his 15th kill on 1 August. He claimed his 24th victory on 11 August 1942. The next day I./JG 53 relocated from
Bereska to Tusov, closer to the front and Crinius shot down three
Mikoyan-Gurevich MiG-3s, bringing his total to 27 victories. Crinius recorded his 49th victory on 27 August which was also the 1,000th victory for I.
Gruppe (1st group) of JG 53. After his 55th victory on 1 September he was promoted to
Feldwebel (Sergeant). Hereafter Crinius was particularly successful, claiming some 40 victories in August and 46 victories in the timeframe 1–22 September, including his 100th on 22 September. He was the 22nd
Luftwaffe pilot to achieve the century mark. Together with
Friedrich-Karl Müller, Crinius was awarded the
Knight's Cross of the Iron Cross with Oak Leaves () on 23 September 1942. Crinius was awarded the Oak Leaves the same day he was awarded the
Knight's Cross of the Iron Cross (). In consequence, Crinius travelled to the presentation ceremony wearing a makeshift Knight's Cross made from an Iron Cross second Class. He was the 127th member of the German armed forces to be so honored. The presentation was made by
Adolf Hitler in October at the
Führerhauptquartier Werwolf, Hitler's headquarters located in a pine forest about north of
Vinnytsia, in
Ukraine. Three other Luftwaffe officers were presented with the Oak Leaves that day by Hitler,
Oberleutnant Müller,
Oberleutnant Wolfgang Tonne and
Leutant Hans Beißwenger. Crinius was promoted to
Leutnant der Reserve (second lieutenant of the reserves) on 1 October 1942. Following the presentation, Müller, Tonne and Crinius were ordered to
Berlin where they made a
propaganda appearance at the "House of the Press". At the same time, I.
Gruppe of JG 53 relocated from the Eastern Front to
Comiso Airfiled in Sicily where they arrived on 10 October. In November 1942, Crinius relocated with I./JG 53 to Tunisia. In Africa, Crinius claimed another 14 victories, including a
B-17 Flying Fortress on 26 December 1942 over
Bizerte. On 13 January 1943, he engaged in aerial combat with
Royal Air Force (RAF)
Supermarine Spitfire fighters near
El Kala, Crinius' aircraft was hit and he was wounded in the thigh. Breaking off combat, he headed for his base but his engine then caught fire. He ditched his damaged
Bf 109 G-2 (
Werknummer 10805) in the sea. He spent 24 hours in the water before being rescued by French sailors and Arabs. After hospitalisation for his wounds, Crinius became a
prisoner of war. ==Later life==
