Siegert received his elementary training in New Zealand, Early on 6 June 1944 Siegert saw action during
Operation Tonga, the British airborne operation launched to precede the beach landings, his No. 190 Squadron aircraft towing a glider carrying men from the
5th Parachute Brigade. On 21 September, the fifth day of the operation, Siegert's squadron was sent to air-drop supplies to the British troops encircled at
Oosterbeek. Unfortunately their fighter escorts were largely grounded by fog over England, and the few that did manage to take off arrived late. As a result, the low-flying transports were an easy target for German
Fw 190 fighters, and of the 117 transport aircraft that took part in operations that day, 23 were shot down and 38 severely damaged. Of the ten aircraft from No. 109 Squadron, seven were lost. Siegert's aircraft was hit by anti-aircraft fire, then attacked by two enemy Fw 190's, one of which his rear-gunner shot down, before he evaded the other in a violent high-speed dive. His full citation read: Siegert continued to take part in No. 190 Squadron's special operations over France, Holland, Belgium, and Norway until the end of the war. ==Post-war career==
