Hamburg Ravensbrück trials
The Hamburg Ravensbrück trials were a series of seven trials for war crimes against camp officials from the Ravensbrück concentration camp that the British authorities held in their occupation zone in Germany in Hamburg after the end of World War II. These trials were heard before a military tribunal; the three to five judges at these trials were British officers, assisted by a lawyer. The defendants included concentration camp personnel of all levels: SS officers, camp doctors, male guards, female guards ("Aufseherinnen"), and a few former prisoner-functionaries who had tortured or mistreated other inmates. In total , 38 defendants were tried in these seven trials; 21 of the defendants were women. Executions relating to these trials were carried out on the gallows at by British hangman Albert Pierrepoint. All seven trials took place at the "Curiohaus" in the Hamburg quarter of Rotherbaum. First trial. The first Ravensbrück trial was held from December 5, 1946 until February 3, 1947 against sixteen Ravensbrück concentration camp staff and officials. All of them were found guilty. One died during trial. The death sentences (except for Salvequart) were carried out on May 2—3, 1947, in Hamelin prison. Percival Treite, a half-British  medical doctor at Ravensbrück, was defended by a dozen former female prisoners, including Special Operations Executive agent, Yvonne Baseden, who wrote letters to the court favorable to him. Ex-prisoner Mary Lindell testified in favor of Treite at the trial saying that Treite "was the only man who was human, the only man who looked after the sick people as a doctor should look after them." The outspoken Lindell also criticized the judge advocate, "who was partial and objectionable, had taken on the cross examination of witnesses himself and prevented other questions from being put which might have been [answered ] in favour of the accused." Nevertheless, Triete was sentenced to death. Three more defendants, the camp leader, "Lagerkommandant" Fritz Suhren, along with "work leader" Hans Pflaum and "Schneidermeister" Friedrich Opitz (below, see the Second Ravensbrück trial), escaped from prison prior to the first trial. The first two of them were apprehended under assumed names in 1949. They were handed over to French authorities, who were conducting another Ravensbrück trial in Rastatt at that time; both men were sentenced to death in that trial and executed by a firing squad on June 12, 1950. Opitz faced trial in November 1947. Second  Ravensbrück trial. In the second Ravensbrück trial, which lasted from November 5 to 27, 1947, the only defendant was Friedrich Opitz age 49, a clothing factory leader in the camp employed there from June 1940 till April 1945. He was recaptured after his earlier escape from prison along with Fritz Suhren and Hans Pflaum (see above). During trial, he was convicted of beating women with truncheons, belts and fists, starving them for missing the quota, keeping them outside in very long roll-calls, and sending them to the gas chamber for (what he called) "being useless", as well as of  kicking at least one Czech female inmate, causing death. He also encouraged his guards to do the same. Opitz received a death sentence, which was carried out on January 26, 1948. Third Ravensbrück trial. In the third Ravensbrück trial, the so-called "Uckermark trial" which took place from April 14 to 26, 1948, five female camp officials of the satellite Uckermark concentration camp, were indicted for the mistreatment of women and the participation in the selection of women for the gas chamber. The Uckermark subcamp was located about one mile from the Ravensbrück concentration camp. It was opened in May  1942 as a prison or parallel concentration camp for teenage girls aged 16 to 21 dubbed criminal or "difficult" by the SS. Girls who reached the upper age limit were transferred back to the Ravensbrück women's camp. Camp administration was provided by the Ravensbrück main camp. In January 1945, the prison for juveniles was closed although the gassing infrastructure was subsequently used for the extermination of "sick, no longer efficient, and over 52 years old women" from Ravensbrück . Braach and Toberentz were acquitted because they had worked at "Uckermark" only while it was still a juveniles camp, and there  were no Allied women there at that time; the camp was exclusively for German girls, whose fate or treatment was outside the remit of the tribunal. Fourth Ravensbrück trial. The fourth trial was held from May to June 8, 1948. The accused were all members of the medical staff of the camp at Ravensbrück, including one inmate who had worked as a nurse. The charges again centered on mistreatment, torture, and sending to gas chambers of women of Allied nationality. Ganzer had already stood trial for her activities in Ravensbrück in 1946 before a Russian military tribunal and had been  acquitted. In Hamburg, she was found guilty, but her death sentence was commuted into lifetime imprisonment on July 3, 1948, which in turn was reduced to 21 years' imprisonment in 1950 and then to 12 years in 1954. She was finally released on June 6, 1961. Fifth Ravensbrück trial. In the fifth trial, three SS members were accused of having killed Allied inmates. The trial lasted from June 16 to 29, 1948. The judgments were handed down on July 15, 1948. Sixth Ravensbrück trial. This trial lasted from July 1 to 26, 1948. Both defendants were accused of having mistreated  Allied inmates. Seventh Ravensbrück trial. Finally, six "Aufseherinnen" (female camp wardens) were tried from July 2 to 21, 1948. The charges were mistreatment of inmates of Allied nationality and participation in the selection of inmates for the gas chamber.
