carrying 1002 prisoners as well as various other transports carrying 1000 Soviet POWs. The total number of prisoners grew to 4500. 495 known deaths occurred in 1941 alone. Until the end of 1940, the majority of prisoners were of German nationality and contained a mix of Asocials, political opponents to the Nazi regime, and various other German national groups. After Neuengamme became an independent concentration camp, the prisoner population grew more diverse, and in the following years the Soviet group followed by the Polish prisoners made up the largest percentage of camp prisoners by nationality. Inmates were from 28 nationalities: Soviets (34,350), Polish (16,900), French (11,500), German (9,200), Dutch (6,950), Belgian (4,800), and Danish (4,800). The prisoner groups included those from the local Jewish community, communists, prostitutes, Gypsies, Jehovah's Witnesses, prisoners of war and many other persecuted groups. Of 106,000 inmates, almost half died. 23,394 victims of Neuengamme and the subcamps can be found listed by name in the Neuengamme Memorial Site's House of Remembrance. In reality, however, it is estimated that there were 26,800 victims of daily camp horrors and about 17,000 victims of the death marches and reception camps. At least 42,900 victims can be verified, even if not by name. According to the testimony of Wilhelm Bahr, an ex-medical orderly, during the trial against Bruno Tesch, 197 Soviet prisoners of war were gassed by prussic acid (Zyklon B) in the arrest bunker of the camp on 25 September 1942. Four weeks later, 251 additional Soviet POWs were gassed in the bunker. There were also 20 Jewish children specifically brought to Neuengamme from Auschwitz in order to be experimented on by Dr. Kurt Heissmeyer from Berlin. Camp personnel and commandants No SS women were stationed at Neuengamme permanently. Female guards were trained at Neuengamme and assigned to its female subcamps. Many of these SS women are known by name, including Käthe Becker, Erna Dickmann, Johanna Freund, Angelika Grass, Kommandoführerin Loni Gutzeit (who was nicknamed "The Dragon of Wandsbek" by the prisoners while serving at Hamburg-Wandsbek), Gertrud Heise, Frieda Ignatowitz, Gertrud Möller, who also served at the Boizenburg subcamp, Lotte Johanna Radtke, Chief Wardress Annemie von der Huelst, and Inge Marga Marggot Weber. Many of the women were later dispersed to female subcamps throughout northern Germany. Today it is known that female guards staffed the subcamps of Neuengamme at Boizenburg, Braunschweig SS-Reitschule, Hamburg-Sasel, Hamburg-Wandsbek, Helmstedt-Beendorf, Langenhorn, Neugraben, Obernheide, Salzwedel,
