Hans Oster born 09-08-1887 in Dresden, Saxony, the son of an Alsatian pastor of the French Protestant Church. He entered the Artillery in 1907. In World War I, he served on the Western Front until 1916, when he was appointed as Captain to the German General Staff. Oster was allowed in the new Reichswehr. He soon found a job in a new organization which Hermann Goering (see Hermann Goering) (see Goering Peter) set up under the Prussian police. He transferred to the Abwehr in October 1933. It was in this connection that he met future conspirators Hans Bernd Gisevius, he died Age 69, on 23-02-1974 and Arthur Nebe, Nebe was executed age 50, on 21-03-1945,

who were then working in the Gestapo. Oster also became a close confidant of Wilhelm Canaris (see Canaris), the head of the Abwehr. Like many other army officers, Oster initially welcomed the Nazi regime, but his opinion soon soured after the 1934 "Night of the Long Knives", in which the Schutzstaffel (SS) extrajudicially murdered many of the leaders of the rival Sturmabteilung (SA leader Röhm)) and their political opponents, including General Kurt von Schleicher (see Schleicher), last Chancellor of Weimar Republic. By 1938, the Blomberg (see Blomberg)-Fritsch Affair (see Fritsch) and Kristallnacht, state-sanctioned pogrom of Jews in Germany, turned his antipathy into a hatred of Nazism. In the course of the Fritsch crisis, Oster met Generaloberst der Artillerie, Ludwig Beck (see Beck), Chief of General Staff, for the first time. After the outbreak of World War II, resistance in the army became more problematic since it could lead to defeat of Germany. However, when Hitler (see Adolf Hitler) (see Alois Hitler) decided to attack France soon after the Polish campaign in 1939, Generaloberst der Infanterie, Franz Halder (see Halder) along with other ranking Generals thought it to be hopelessly unrealistic and again entertained the idea of coup, urged by Oster and Canaris. However, when Hitler vowed to destroy the "spirit of Zossen" , Zossen was where headquarters of Army High Command was located, by which he meant defeatism, Halder feared that their conspiracy was about to be discovered and destroyed all incriminating documents. Meanwhile, in an act that even other conspirators would have regarded as treason, Oster informed his friend Bert Sas, Sas died in a crash, age 56, 20-10-1948, the Netherlands' military attaché in Berlin, Joseph Goebbels (see Goebbels) was the Gauleiter of Berlin, more than twenty times of the exact date of the repeatedly delayed invasion of the Netherlands (see About) and (Ackermans). Sas passed the information to his government, but was not believed. Oster calculated that his "treason" could cost lives of 40,000 German soldiers and wrestled with his decision, but concluded that it was necessary to prevent millions of deaths that would occur in what would be undoubtedly a protracted war should Germany achieve an early victory. Others still opposed Hitler and the Nazi regime, but felt that his enormous popularity with the people made any action impossible. Tireless, Oster nevertheless succeeded in rebuilding an effective resistance network. In 1941, when the systematic extermination of Europeans Jews began with the invasion of Soviet Union, his Abwehr group established contact with Generalmaor der Infanterie, Henning von Tresckow's (see Tresckow) resistance group in Army Group Center. In 1942, his most important recruit was General der Infanterie, Friedrich Olbricht (see Olbricht), head of the General Army Office headquartered at the Bendlerblock in central Berlin, who controlled an independent system of communications to reserve units all over Germany. Oster's Abwehr group supplied British-made bombs to Tresckow's group for their various attempts to assassinate Hitler in 1943. Oster was arrested one day after the failed 20 July Plot to assassinate Hitler. On 04-04-1945, the diaries of Admiral Canaris were discovered and, in a rage upon reading them, Hitler ordered that the conspirators be executed. On 08-04-1945, Oster, Dietrich Bonhoeffer (see Bonhoeffer), Wilhelm Canaris, and other anti-Nazis were convicted and sentenced to death by an SS drumhead court-martial presided over by Otto Thorbeck, He died age 64, on 10-10-1974.
At dawn the next day, Oster, Bonhoeffer and Canaris were hanged in Flossenbürg concentration camp. They were forced to strip naked before being taken to the gallows. The camp was liberated two weeks later by American forces. They all were cremated and the ashes came in a ash mass grave in Flössenbürg.
Execution place in Flössenburg.
