Military personnel from the Kingdom of Saxony

Hans Paul Oster (9 August 1887 – 9 April 1945) was a general in the Wehrmacht and a leading figure of the anti-Nazi German resistance from 1938 to 1943. As deputy head of the counter-espionage bureau in the Abwehr (German military intelligence), Oster was in a good position to conduct resistance operations under the guise of intelligence work.
He was involved in the Oster conspiracy of September 1938 and was arrested in 1943 on suspicion of helping Abwehr officers caught helping Jews to escape Germany. After the failed 1944 July Plot on Hitler's life, during interrogation, he named Admiral Wilhelm Canaris, the head of Abwehr, as the "spiritual founder of the Resistance Movement". The Gestapo arrested Canaris and eventually found his diaries, in which Oster's anti-Nazi activities were revealed. In April 1945, he was hanged with Canaris and Dietrich Bonhoeffer at Flossenbürg concentration camp.

Max Immelmann (21 September 1890 – 18 June 1916) PLM was the first German World War I flying ace. He was a pioneer in fighter aviation and is often mistakenly credited with the first aerial victory using a synchronized gun, which was in fact achieved on 1 July 1915 by the German ace Kurt Wintgens. He was the first aviator to receive the Pour le Mérite, colloquially known as the "Blue Max" in his honour, being awarded it at the same time as Oswald Boelcke. His name has become attached to a common flying tactic, the Immelmann turn, and remains a byword in aviation. He is credited with 15 aerial victories.

Friedrich Olbricht (4 October 1888 – 21 July 1944) was a German general during World War II. He is known for being one of the plotters involved in the 20 July Plot, an attempt to assassinate Adolf Hitler in 1944.
Olbricht was a senior staff officer, with the rank of lieutenant general. He was secretly in contact with most of the leaders of the resistance. They briefed him on their various plots and he placed sympathetic officers in key positions. Olbricht quietly encouraged field commanders to support the resistance. By late 1943, his office was the centre of Resistance plotting, under Claus von Stauffenberg. Had the 20 July plot to assassinate Adolf Hitler been successful, Olbricht would have assumed the position of minister of war in a post-Nazi regime.
