The children of Sinti and Roma were also victims, interned with their families in the municipal camps and studied and classified by racial scientists. Between 1933 and 1939, authorities took many Sinti and Roma children from their families and brought them to special homes for children as wards of the state.

Gypsy schoolchildren who were truant were deemed delinquent and sent to special juvenile schools; those unable to speak German were deemed feeble-minded and sent to “special schools” for the mentally handicapped.

Like Jewish children, Gypsy boys and girls also commonly endured the taunts and insults of their classmates, until March 1941 when the regime excluded Gypsies from the public schools.

Heinrich Himmler Memorandum, December 8, 1938:

Experience gained in combating the Gypsy nuisance, and knowledge derived from race-biological research, have shown that the proper method of attacking the Gypsy problem seems to be to treat it as a matter of race. Experience shows that part-Gypsies play the greatest role in Gypsy criminality. On the other hand, it has been shown that efforts to make the Gypsies settle have been unsuccessful, especially in the case of pure Gypsies, on account of their strong compulsion to wander. It has therefore become necessary to distinguish between pure and part-Gypsies in the final solution of the Gypsy question.
 

To this end, it is necessary to establish the racial affinity of every Gypsy living in Germany and of every vagrant living a Gypsy-like existence. I therefore decree that all settled and non-settled Gypsies, and also all vagrants living a Gypsy-like existence, are to be registered with the Reich Criminal Police Office-Reich Central Office for Combating the Gypsy Nuisance.
 

The police authorities will report (via the responsible Criminal Police offices and local offices) to the Reich Criminal Police Office-Reich Central Office for Combating the Gypsy Nuisance all persons who by virtue of their looks and appearance, customs or habits, are to be regarded as Gypsies or part-Gypsies.

During May 1940, about 3,100 were sent to Jewish ghettos in the Government-General: others may have been added to Jewish transports from Berlin, Vienna, and Prague to Nisko, Poland (the sight of an aborted reservation to which Jews were deported). These measures were taken against Gypsies who had no claim to exemption because of having an Aryan spouse or having been regularly employed for five years.

At a conference held on January 30, 1940, a decision was taken to expel 30,000 Gypsies from Germany to the territories of occupied Poland. Einsatzgruppen reports from groups operating in the occupied territories of the Soviet Union mention the murder of thousands of Gypsies along with the massive extermination of the Jews in these areas.

The legal status of Gypsies and Jews, determined irrevocably by the agreement between Justice Minister Thierack and SS Reichsfuehrer Himmler on 18 September 1942, removing both groups from the jurisdiction of any German court, confirmed their fate.

Now with all legal obstacles removed, the deportations and executions of the Gypsies came under Himmler's full authority. On December 16, 1942, Himmler issued an order to send all Gypsies to the concentration camps, with a few exceptions.

In western and southern Europe, the fate of Sinti and Roma varied from country to country, depending on local circumstances. Across German-occupied Europe, Gypsies, like Jews, were interned, killed, or deported to camps in Germany or eastern Europe.

The collaborationist regime of Vichy France interned 30,000 Gypsies, many of whom were later deported to Dachau, Ravensbrück, Buchenwald,  and other camps. In Croatia, members of the local fascist Ustasha movement killed tens of thousands of Gypsies, along with Serbs and Jews.

Adolf Eichmann telegram from Vienna to the Gestapo:

Regarding transport of Gypsies be informed that on Friday, October 20, 1939, the first transport of Jews will depart Vienna. To this transport 3­4 cars of Gypsies are to be attached. Subsequent trains will depart from Vienna, Mahrisch-Ostrau and Katowice.

The simplest method is to attach some carloads of Gypsies to each transport. Because these transports must follow schedule, a smooth execution of this matter is expected. Concerning a start in the Altreich (Germany proper) be informed that this will be coming in 3­4 weeks.

In Romania in 1941 and 1942, thousands of Gypsies were expelled, alongside Jews, to Transnistria (western Ukraine) where most of the deportees died from disease, starvation, and brutal treatment. In Serbia, in the fall of 1941, German army firing squads killed almost the entire adult male Gypsy population, alongside most adult male Jews, in  retaliation for German soldiers killed by Serbian  Resistance fighters.

Most often, the German police deported Roma in the Greater German Reich to Auschwitz-Birkenau, where the camp authorities housed them in a special compound that was called the "Gypsy family camp." Some 23,000 Roma, Sinti and Lalleri were deported to Auschwitz altogether. In the so-called Gypsy compound, entire families lived together.

SS medical researchers assigned to the Auschwitz complex, such as SS Captain Dr. Josef Mengele, received authorization to choose human subjects for pseudoscientific medical experiments from among the prisoners in the Auschwitz concentration camp complex. Mengele chose twins and dwarves, some of them from the Gypsy family camp, as subjects of his experiments.

Approximately 3,500 adult and adolescent Roma were prisoners in other German concentration camp; medical researchers selected subjects from among the Roma incarcerated in Ravensbrück, Natzweiler-Struthof, and Sachsenhausen concentration camps for their experiments, either on site in the camps or at nearby institutes.

Conditions in the Gypsy compound at Auschwitz-Birkenau were contributed to the spread of infectious disease and epidemics--typhus, smallpox, and dysentery--which severely reduced the camp population. In late March, the SS murdered approximately 1,700 Roma from the Bialystok region in the gas chambers; they had arrived a few days earlier and many, though by no means all, were ill.

Roman Mirga a Gypsy survivor from Auschwitz recalls the gassing process:

I suddenly heard music.  In the distance violins were playing 'The Blue Danube'...  It was intended to calm the Jews going inside,  soap and towels in their hands, no doubt believing they were taking a bath.  Except that it was not a bath-house, but a crematorium. 

The Gypsy orchestra was there...their music helping to make a smooth transition for the Jews from life to death

In May 1944, the camp leadership decided to murder the inhabitants of the Gypsy compound. The SS guards surrounded and sealed off the compound. When ordered to come out, the Roma refused, having been warned and having armed themselves with iron pipes, shovels, and other tools used for labor.

The SS leaders chose not to confront the Roma directly and withdrew. After transferring as many as 3,000 Roma capable of work to Auschwitz I and other concentration camps in Germany in the late spring and early summer of 1944, the SS moved against the remaining 2,898 inmates on August 2. Most of the victims were ill, elderly men, women, and children.

The camp staff killed virtually all in the gas chambers of Birkenau. A handful of children who had hidden during the operation were captured and killed in the following days. At least 19,000 of the 23,000 Roma sent to Auschwitz died there.

It is widely recognized that the persecution and murder of the Roma and Sinti has been largely overlooked by most scholars studying the Holocaust. Because most Romani communities of Eastern Europe were much less organized than the Jewish communities, it has been more difficult to assess the actual number of victims, though it is believed to range from 220,000 to 1,500,000.
