Question: In what city and country was the  Jagdgeschwader 77 based? Passage:Born in Cologne-Lindenthal, Reinert volunteered for military service in the National Socialist Luftwaffe in 1938. Following flight training, he was posted to Jagdgeschwader 77 (JG 77—77th Fighter Wing). He fought in Operation Barbarossa, the German invasion of the Soviet Union, and claimed his first aerial victory on 8 August 1941. He received the Knight's Cross of the Iron Cross following his 53rd aerial victory. Accumulating further victories, he surpassed the century mark in October 1942 for which he was awarded the Knight's Cross of the Iron Cross with Oak Leaves. In November 1942, his unit was transferred to the Mediterranean theatre in support of the Afrika Korps. There, Reinert claimed 51 victories against the Western Allies. In August 1943, he was appointed Staffelkapitän (squadron leader) of 1. Staffel (1st squadron) of JG 77, and in February 1944 the 8. Staffel of Jagdgeschwader 27 (JG 27—27th Fighter Wing) based in France. Reinert was then appointed Gruppenkommandeur (group commander) of IV. Gruppe (4th group) of JG 27 and, credited with 174 aerial victories, received the Knight's Cross of the Iron Cross with Oak Leaves and Swords on 30 January 1945. He then received conversion training to the then new Messerschmitt Me 262 jet fighter and was posted to Jagdgeschwader 7 (JG 7—7th Fighter Wing), an all-jet fighter wing.

Question: How many people attended the conference held near Berlin in January 1942? Passage:Following the invasion of Poland in 1939 most of the 3.5 million Polish Jews were rounded up and put into newly established ghettos by Nazi Germany. The system was intended to isolate the Jews from the outside world in order to facilitate their exploitation and abuse. The supply of food was inadequate, living conditions were cramped and unsanitary, and the Jews had no way to earn money. Malnutrition and lack of medicine led to soaring mortality rates. In 1941, the initial victories of the Wehrmacht over the Soviet Union inspired plans for the German colonisation of occupied Poland, including all territory within the new district of General Government. At the Wannsee Conference held near Berlin on 20 January 1942, new plans were outlined for the genocide of the Jews, known as the "Final Solution" to the Jewish Question. The extermination programme was codenamed Aktion Reinhard in German, to differentiate it from the Einsatzgruppen mass killing operations in territories conquered by Nazi Germany, in which half a million Jews had already been annihilated.

When he was not confined to his bed, he delivered lectures to Armée de Libération Nationale (ALN) officers at Ghardimao on the Algero-Tunisian border. He made a final visit to Sartre in Rome.
