By early 1941 Gender's flying training was complete and he was posted to
No. 33 Squadron as a
sergeant pilot. This unit, equipped with
Hawker Hurricane fighters, was based at
Eleusis in Greece and flying as escorts to bombers attacking the Italian forces along the Albanian border. Following the
German invasion of Greece, the squadron began encountering the
Luftwaffe. On 14 April the squadron's airfield was subject to a strafing attack by
Messerschmitt Bf 109 fighters. Genders was able to take off and shoot down one of the attacking aircraft, and also damaged a second. He destroyed three
Junkers Ju 87 dive bombers and another Bf 109 on 23 April. On 3 May, with the squadron now operating over
Crete, Genders claimed two
Junkers Ju 88 medium bombers as probably destroyed and also damaged two others.
Egypt After its campaign on Crete, what was left of No. 33 Squadron was evacuated to Egypt to rebuild after the losses of the previous weeks. Once it was operational again it carried out defensive patrols from
Heliopolis. It then flew from
Sidi Barrani in support of the British efforts along the Egypt-Libya border in the
Western Desert campaign. Genders destroyed two
Fiat G.50 fighters of the
Regia Aeronautica (Royal Italian Air Force) on 17 June. He damaged a Ju 88 on 22 November, and also shared in the destruction of a
Savoia-Marchetti SM.79 medium bomber the same day. The squadron was operating from
Landing Ground 125 by this time and in early 1942, it started training up on the
Curtiss P-40 Kittyhawk fighter. Genders was rested in March and was
commissioned as a
pilot officer. The following month he was awarded the
Distinguished Flying Medal. He briefly served with No. 53 Repair and Salvage Unit before, in May, he was posted to
No. 103 Maintenance Unit (MU) at
Aboukir. This was tasked with repairing aircraft and Genders gained considerable experience across a wide variety of aircraft types. The unit also prepared specially adapted
Supermarine Spitfire fighters for high-altitude interception of German reconnaissance aircraft. Genders was one of three pilots tasked with flying sorties with these fighters and on 26 June he and another pilot damaged a
Junkers Ju 86P reconnaissance aircraft. The next day, he again successfully intercepted a Ju 86P but was only able to share in damaging it. He shared in the destruction of a Ju 86P on 6 September. These duties were risky and on one occasion Genders ran out of fuel while pursuing a German aircraft, and had to bale out over the sea. After spending nearly a day in the water before reaching the shore, he had walk nearly before reaching the Allied positions. On 21 October he shot down a Ju 88. In May 1943, now holding the rank of acting
flight lieutenant, Genders was assigned to
No. 1 British Airways Repair Unit at Heliopolis. He remained there for nearly a year until being posted to No. 136 MU at Berca in February 1944. Genders returned to the United Kingdom in April 1945 with a posting to the aircraft manufacturer
Airspeed Limited at
Portsmouth as a
test pilot. ==Postwar==
