'''Warsaw''' was a [[Nazi concentration camps|Nazi concentration camp]] in [[Occupation of Poland (1939–1945)|German-occupied Poland]] during [[World War II]]. It was formed on the base of the now-nonexistent [[Gęsiówka]] prison, in what is today the [[Warsaw]] neighbourhood of [[Muranów]], on the order of [[Reichsführer-SS]] [[Heinrich Himmler]]. The camp operated from July 1943 to August 1944.
 
Located in the ruins of the [[Warsaw Ghetto]], {{Abbr|KL|Konzentrationslager}} Warschau first functioned as a camp in its own right, but was demoted to a branch of the [[Majdanek concentration camp]] in May 1944. In late July that year, due to [[Operation Bagration|the Red Army approaching Warsaw]], [[the Nazis]] started to evacuate the camp. Around 4,000 inmates were forced to march on foot to [[Kutno]], {{convert|120|km|mi|abbr=on}} away; those who survived were then transported to [[Dachau concentration camp|Dachau]]. On 5 August 1944, KL Warschau was captured by [[Battalion Zośka]] during the [[Warsaw Uprising]], liberating 348 [[Jews]] who were still left on its premises. It was the only German camp in Poland to be liberated by [[Resistance during World War II|anti-Nazi resistance]] forces, rather than by [[Allies of World War II|Allied]] troops. After the [[Red Army]] definitively expelled the Germans from Warsaw in January 1945, the new communist administration continued to run the buildings as a forced labour camp, and then as a prison, until it was closed in 1956. All the camp's premises were demolished in 1965.
{{The Holocaust}}
'''The Warsaw concentration camp''' ({{lang-de|'''Konzentrationslager Warschau'''}}, short '''''KZ Warschau''''') was an associated group of [[Nazi concentration camp|Nazi concentration]] and [[extermination camp]]s located in [[Germans|German]]-[[occupied]] [[Warsaw]], in [[Poland]].
 
The ''[[Encyclopedia of Camps and Ghettos, 1933–1945|Encyclopedia on Camps and Ghettos]]'' says that a total of 8,000 to 9,000 inmates were held there, while [[Bogusław Kopka]] estimates the number as at least 7,250 prisoners, all but 300 of whom were Jews from various European countries, in particular from [[Hungary]] and [[Greece]]. The Jewish inmates were used as [[Forced labour under German rule during World War II|forced labor]] to clean the ruins of the Warsaw Ghetto, with the ultimate goal of creating a park in the former ghetto's territory. They also had to find and sort whatever precious items were still left on its territory. The camp and adjacent ruins were additionally used by the [[Nazi Germany|German administration]] as a place of [[Executions in the ruins of the Warsaw Ghetto (1943–1944)|execution]], the victims being [[Political prisoners in Poland|Polish political prisoners]], Jews caught on the "[[Nazi racial theories|Aryan]] side", and generally people [[Łapanka|rounded up]] on the streets of Warsaw. About 4,000 to 5,000 prisoners died during the camp's existence,<ref name="USHMM">{{cite encyclopedia|year=2009|title=Early Camps, Youth Camps, and Concentration Camps and Subcamps under the SS-Business Administration Main Office (WVHA)|publisher=[[Indiana University Press]]|___location=[[Bloomington, Ind.]]|url=https://www.ushmm.org/online/camps-ghettos-download/EncyclopediaVol-I_PartB.pdf|access-date=14 September 2021|last=Finder|first=Gabriel N.|author-link=Gabriel N.

The [[Polish Institute of National Remembrance]] (IPN) estimates that the number of victims who died at these camps to be "not less than tens of thousands". However, it has refrained from making a more precise estimate due to scant evidence. Some other estimates place the number of the camp's victims as high as 200,000 (mostly [[gentile]] [[Poles]]).{{fact|date=February 2007}}

==Estalibishment date controversy==
 
== Name ==
The earliest official mention of the ''KZ Warschau'' is from [[June 19]], [[1943]] which referred to the [[concentration camp]] in the ruins of the [[Warsaw Ghetto]]. However, the term ''KZ Warschau'' was also used to describe similar camps that were discovered at an earlier date.
[[File:Stroop_Report_-_Warsaw_Ghetto_Uprising_02.jpg|thumb|The building of the Wołyń Caserns was commonly known as Gęsiówka. Photo of the burnt edifice taken during the [[Warsaw Ghetto Uprising]]|alt=A black-and-white photo of a partially destroyed building of the Wołyń Caserns (commonly known as Gęsiówka), taken during the Warsaw Ghetto Uprising.]]
During the first nine months, the Warsaw concentration camp functioned in its own right. At this time it carried the official name of {{Langx|de|Waffen-SS Konzentrationslager Warschau|label=none}} (often referred to as {{Langx|de|KL Warschau|label=none}}{{Sfn|Kopka|2007|p=41}} for short in Nazi documents and in Polish scholarship, or, in most contemporary German-language works, {{Langx|de|[[wikt:KZ|KZ]] Warschau|label=none}}).<ref>{{Cite book|last=Kopka|first=Bogusław|title=Das KZ Warschau : Geschichte und Nachwirkungen|publisher=Instytut Pamieci Narodowej|year=2010|isbn=978-83-7629-079-9|___location=Warszawa|language=de|oclc=699705139|orig-year=2007}}</ref><ref name="Lehnstaedt" /> In May 1944, {{Langx|de|KL Warschau|label=none|italic=unset}} became a branch of [[Majdanek concentration camp]],{{Efn|Majdanek also served as an extermination camp}} so the camp's name changed to {{Langx|de|Waffen-SS Konzentrationslager Lublin – Arbeitslager Warschau|lit=Waffen-SS Concentration Camp Lublin – Labour Camp Warsaw|label=none}}. It was also sometimes referred to in German sources as {{Langx|de|Arbeitslager Warschau|label=none}}.<ref name=":13" />
 
The name {{Langx|pl|Gęsiówka|label=none}} ([[International Phonetic Alphabet|IPA]]: {{IPAc-pl|g|ę|'|ś|u|f|k|a}}) often appears in Polish sources. This is due to the fact that the camp occupied the complex of now non-existent {{Interlanguage link|Koszary Wołyńskie|lt=Wołyń Caserns|pl}}, which were relatively well-preserved after the Warsaw Ghetto Uprising. The caserns, at the corner of then-existing Gęsia and Zamenhof streets, were a military prison before [[World War II]]. During German occupation, they accommodated the central prison for the Jewish district, the {{Interlanguage link|Wychowawczy obóz pracy policji bezpieczeństwa w Warszawie|lt=correcting labour camp of the ''Sicherheitspolizei''|pl}}, as well as the {{Langx|de|[[Judenrat]]|label=none}}.<ref name="Kombatanci">{{Cite journal|date=June 2016|title=Niemiecki obóz koncentracyjny w Warszawie: Wspólna historia Żydów i Polaków|url=https://kombatanci.gov.pl/images/DOC/Kombatant/2016/201606.pdf|journal=[[Office for War Veterans and Victims of Oppression]]|volume=6|language=pl|issue=306|pages=24–29|access-date=14 September 2021|archive-date=20 August 2018|archive-url=https://web.archive.org/web/20180820165651/http://www.kombatanci.gov.pl/images/DOC/Kombatant/2016/201606.pdf|url-status=live}}</ref> The prison complex became colloquially known as {{Langx|pl|Gęsiówka|label=none}} (named for Gęsia street), which nickname transferred to {{Langx|de|KL Warschau|label=none|italic=unset}} as well.{{Sfn|Szarota|2014|p=364}}{{Sfn|Kopka|2007|p=43}} Supporters of the [[Warsaw concentration camp#Discredited extermination camp story|Trzcińska's theory]] tend to prefer the German name, which Aleksandra Ubertowska says has to do with the name being perceived as more serious.<ref>{{Cite journal|last=Ubertowska|first=Aleksandra|date=2008-11-02|title=Bogusław Kopka Konzentrationslager Warschau.

Nevertheless, it is estimated that ''KZ Warschau'' was in operation from the autumn of [[1942]] until the Warsaw Uprising. The First Commander of the camp was ''[[SS]]-[[Obergruppenführer]]'' [[Wilhelm Goecke]], a former [[Mauthausen-Gusen concentration camp]] commander. In addition to [[genocide|genocidal]] purposes, the camp was designed to provide the [[Nazi Party]] with a work force to clean up the leveled ruins of the former Warsaw Ghetto into a future [[recreation]]al area for the SS.
 
After World War II, the camp, although with changed purposes, was still run by Communist authorities under other names (see the relevant [[Warsaw concentration camp#Postwar|section]] for details).{{Sfn|Kopka|2007|p=116}}{{Sfn|Łuszczyna|2017}}
The exact date of the camp's creation is unknown. Some historians (IPN among them) have suggested that it was created following the orders of ''SS-Obergruppenführer'' [[Oswald Pohl]] on [[June 11]] [[1943]]. However, others have (among them historian and [[IPN]] [[judge]] [[Maria Trzcińska]]) claimed that the camp was already operational prior to the [[Warsaw Ghetto Uprising]]. The factual basis for this aforementioned claim is that on [[October 9]], [[1942]], [[Heinrich Himmler]] issued an order in which he stated:
 
==Creation==
<blockquote>''I've issued orders and requested that all the so-called arms factories workers working only as tailors, furriers or bootmakers be grouped in the nearest concentration camps, that is in Warsaw and [[Majdanek|Lublin]].''</blockquote>
[[File:Oswald_Pohl_KL_Warschau_1943.jpg|thumb|Letter from [[Oswald Pohl]] to [[Heinrich Himmler]], dated 23 July 1943, on the creation of KL Warschau, noting arrival of the first 300 prisoners|alt=A typewritten letter from Oswald Pohl (signed at the bottom) to Heinrich Himmler, dated 23 July 1943. The letter, written in German, relates about the creation of KL Warschau and notes about the arrival of the first 300 prisoners.]]
According to [[Bogusław Kopka]], the first person behind the idea of creating a new concentration camp in Warsaw was [[Heinrich Himmler]], [[Reichsführer-SS|head]] of the ''[[Schutzstaffel]]'' (SS), who mentioned it in a letter dated 9 October 1942.<ref name=":0">{{Cite book|url=https://books.google.com/books?id=CsErAAAAYAAJ&dq=Himmler+16+February+1943&pg=PA254|title=Trials of War Criminals Before the Nuernberg Military Tribunals Under Control Council Law No. 10, Nuremberg, October 1946-April 1949|date=1950|publisher=[[U.S. Government Printing Office]]|volume=V|___location=[[Washington, D.C.]]|pages=254–255, 623|language=en|access-date=19 November 2021|archive-date=27 December 2021|archive-url=https://web.archive.org/web/20211227154003/https://books.google.com/books?id=CsErAAAAYAAJ&dq=Himmler+16+February+1943&pg=PA254|url-status=live}}</ref>{{Sfn|Kopka|2007|p=28}} The letter informed the local posts of SS and the ''[[Wehrmacht]]'' in the [[General Government]] that all Jewish craftsmen who so far had managed to avoid deportation to [[extermination camp]]s were to be "assembled by SS-''[[Obergruppenführer]]'' [[Friedrich-Wilhelm Krüger|Krüger]] and SS-''Obergruppenführer'' [[Oswald Pohl|Pohl]] on the spot, i.e. in the concentration camps in [[Warsaw]] and [[Lublin]]{{Efn|The "Lublin camp" (Majdanek) was already functioning when the letter was written}}".{{Sfn|Salter|2007|p=44}}<ref>{{Cite book|url=http://digisam.ub.uni-giessen.de/ubg-ihd-hl/3223411|title=Faschismus – Getto – Massenmord : Dokumentation über Ausrottung und Widerstand der Juden in Polen während des Zweiten Weltkrieges|publisher=[[Żydowski Instytut Historyczny]]/Rütten & Loening|year=1961|editor-last=Berenstein|editor-first=Tatiana|pages=445–446|language=de|editor-last2=Eisenbach|editor-first2=Artur|editor-last3=Mark|editor-first3=Bernard|editor-last4=Rutkowski|editor-first4=Adam}}{{Dead link|date=August 2024 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> The two camps were also intended to host Jewish labourers, who were supposed to be working for weapons factories operating on-site; as for production facilities, they were planned to be successively moved to concentration camps near Lublin, and then farther east.{{Sfn|Longerich|2011|p=621}} Himmler assumed that concentrating all Jewish labour in the camps controlled by the [[SS Main Economic and Administrative Office]] (SS-WVHA) would be the basis for the creation of an SS economic empire in the East.{{Sfn|Kopka|2007|p=29-31}} His ideas, however, were met with resistance from the military, the police and civil administration of the General Government, as well as from the [[Reich Ministry of Armaments and War Production]] and from German companies using Jewish [[slave labour]]. Himmler was thus unable to bring his idea to fruition, so the concentration camp in Warsaw did not appear, nor did all factories using Jewish labour become controlled by SS.{{Sfn|Kopka|2007|pp=31-32}}
 
As plans to demolish the [[Warsaw Ghetto]] appeared, Himmler soon returned to the idea of creating a concentration camp in Warsaw. In a letter dated 16 February 1943, Himmler instructed SS-''Obergruppenführer'' Oswald Pohl, head of SS-WVHA, to create a concentration camp in the "Jewish district" and ordered all German-owned private enterprises operating in the Ghetto to be relocated there.<ref name=":0" /> The camp, together with its enterprises and inhabitants, was planned to be "transported as quickly as possible to Lublin and nearby areas". On the same day, Himmler also wrote a letter to SS-{{Abbr|Ogruf|Obergruppenführer}} Friedrich-Wilhelm Krüger, Higher [[SS and police leader]] for the General Government, which demanded that the buildings of the deserted ghetto be demolished after the concentration camp was transported to Lublin.<ref name=":0" /> The task of demolition, it was suggested, was to be handed over to the local Jews.<ref name="Pohl">{{cite book|last=Pohl|first=Dieter|title=Concentration Camps in Nazi Germany: The New Histories|date=2009|publisher=Routledge|isbn=978-1-135-26321-8|editor1-last=Wachsmann|editor1-first=Nikolaus|editor-link1=Nikolaus Wachsmann|pages=156–157|language=en|editor2-last=Caplan|editor2-first=Jane|author-link=Dieter Pohl}}</ref> The idea's implementation was marred with numerous difficulties, so when the Germans decided to accelerate the deportations on 19 April, they met strong resistance from the Jews, who began the [[Warsaw Ghetto Uprising]].<ref name="Pohl" />{{Sfn|Berenstein|Rutkowski|1967|p=4}}{{Sfn|Mix|2008|p=122}} The concentration camp failed to materialise again, and only part of the enterprises, together with some of the Jews, were evacuated to the concentration camps in Majdanek, [[Trawniki concentration camp|Trawniki]], and [[Poniatowa concentration camp|Poniatowa]].<ref name="Pohl" />{{Sfn|Kopka|2007|p=38}}
==Organization==
 
The idea of the camp was revived once again after the failure of the Warsaw Ghetto Uprising. [[SS-Brigadeführer|SS-''Brigadeführer'']] [[Jürgen Stroop]], who led the efforts aimed at quashing the insurgency, proposed on 16 May 1943, the day the uprising came to an end, to convert the [[Pawiak prison]] to a concentration camp. The building was previously used by the [[Sicherheitsdienst|SD]] and the ''[[Sicherheitspolizei]]'' (Security Police).{{Sfn|Stroop|1943|ps=It is proposed to change the Dzielna Prison into a concentration camp and to use the inmates to remove, collect and hand over for reuse the millions of bricks, the scrap-iron, and other materials.}} It is suggested that by creating such a camp, the Germans wanted to destroy evidence of the crimes committed during the suppression of the uprising<ref name=":11">{{Cite web|last=Wieczorek|first=Paweł|title=Pamiętamy: KL Warschau (19.07.1943 – 01.08.1944)|url=https://1943.pl/artykul/pamietamy-kl-warschau-19-07-1943-01-08-1944/|access-date=2022-06-02|website=Muzeum Getta Warszawskiego|language=pl-PL}}</ref> as well as to enrich themselves by the loot that would be collected in the rubble by slave labourers.<ref name=":10" /> Himmler agreed to the proposal and issued the order, which read:<ref name=":0" />
The camp was composed of five parts located in different areas of Warsaw, all of which were connected by railway and were under unified organization and one command. In chronological order of opening:
 
{{Blockquote|text=I herewith order, that the <em>Dzielna prison</em> [Pawiak prison – note] in the former <em>ghetto of Warsaw</em>, is to be transformed into a concentration camp. The prisoners are to gather and secure the millions of building stones, scrap iron, and other building material from the former ghetto. Special care is to be taken for the secure guards of the prisoners during this work.

I instruct [...] to make sure that during this cleaning up the city center of the former ghetto is to be flattened completely and every cellar and every canalization is to be filled in.
The overall area of the camp was 1.2&nbsp;km², with 119 barracks purposely built to hold approximentally 40,000 prisoners. The camp infrastructure included several [[crematoriums]], including one electrical and the guards included [[Ukrainians]] and [[Latvians]].

==Operation==
 
Eventually, Pawiak's status as a prison did not change, but the concentration camp was created on nearby Gęsia street, which was also located inside the Ghetto walls. One of the reasons why {{Langx|pl|Gęsiówka|label=none}} was chosen was because it was among the only buildings left intact in the area previously occupied by the Ghetto.<ref name="Sofsky" /> In addition to that, Bogusław Kopka argues that its position within a deserted area with restricted access to civilians was also a factor. Another advantage was the camp's proximity to the warehouses at ''[[Umschlagplatz]]'' as well as German militarised units: an SS outpost on {{Interlanguage link|ulica Żelazna w Warszawie|lt=Żelazna|pl}} street, a strong German army command at {{Interlanguage link|ulica Stawki w Warszawie|lt=Stawki|pl}} street and the staff of the Pawiak prison, all of whom could be quickly dispatched in case of mutiny.<ref name="Kombatanci" />
===Pabst Plan===
[[Image:Warsch.JPG|thumb|200px|Aerial photo of the ruins of the Ghetto, 1943 ([[US Air Force]])]]
 
On 19 July 1943, the first 300 prisoners, who were German and predominantly criminals, were transported from [[Buchenwald concentration camp]]. This date is considered to be the day when {{Langx|de|KL Warschau|label=none|italic=unset}} started operation.<ref name="USHMM" />{{Sfn|Kopka|2007|p=40}}
According to the [[Pabst Plan]], prior to the Warsaw Uprising, Warsaw was to be turned into a provincial German city. To ensure this modification, the population of the city was to be reduced from over a million to less than 500,000 inhabitants. To accomplish this goal, the Jewish population was grouped together in the Warsaw Ghetto before being eventually removed and exterminated. The Nazis next step in their plan wasthe removal of the gentile population.
 
== Description ==
The gentile population of Warsaw became the target of the ''[[łapanka]]'' policy, in which ''[[Wehrmacht]]'' and police rounded up civilians on a street. Between 1942 and 1944, there were approximately 400 victims of łapanka in Warsaw daily. The individuals caught were first transferred to the KZ Warschau complex; from there, many were transported to other concentration and labor camps in Poland.

=== Location and facilities ===
===Executions===
{{See also|Gęsiówka}}
The Warsaw concentration camp was created inside a closed and deserted zone of the former ghetto, which was surrounded by walls regularly patrolled by German guards and the police.{{Sfn|Kopka|2007|p=46, 49}} {{Langx|de|Gęsiówka|label=none}}, a former military prison, and spaces along Gęsia Street were adapted for the purposes of the camp. Since none of the camp's buildings survived, its general appearance and facilities can only be deduced from witness testimony, aerial photography, and photos made during [[exhumation]]s and after the camp's liberation.

=== Personnel ===
According to [[IPN]], most victims were executed by gunfire, both in the camps and in an adjoining "security zone", with some of the [[hostage]]s [[public execution|publicly executed]] in the streets of Warsaw. Numerous others were gassed in the [[gas chamber]]s at Gęsia Street, where a considerable quantity of [[Zyklon B]] was found after the war (the first gassing there happened on [[October 17]] [[1943]], killing 150 Poles from the Warsaw roundups and 20 Jews from [[Belgium]]). A relatively small number of victims were tortured to death at "the colloseum" or [[hanged]] at the so-called "death wall" at Koło.
Initially, about 380 SS soldiers were maintaining the concentration camp, approximately the size of a [[Company (military unit)|company]].{{Sfn|Kopka|2007|p=86}} The number of SS guards was relatively low, as the former ghetto, itself a closed zone, was surrounded by patrolled walls, and due to the fact that the [[prisoner functionaries]] were Germans from the initial transport and were thus delegated much more power than was usual for their counterparts in other camps.<ref name=":13" /><ref name=":10" /> The original SS unit was gathered from various other camps, including the Trawniki concentration camp and the [[Sachsenhausen concentration camp]]. Following the attachment to Majdanek in May 1944, they were replaced with SS personnel from Lublin, and the guard was reduced to 259 people.<ref name="USHMM" />{{Sfn|Kopka|2007|p=86, 89}} Leadership positions were occupied by high- and middle-ranking SS members who were pre-war [[Third Reich]] citizens (''[[Reichsdeutsche]]''), while the rank-and-file were usually recruited among the ''[[Volksdeutsche]]'', mainly from [[Southeast Europe]] but also from other areas.{{Sfn|Kopka|2007|p=86, 89}}
 
In comparison with other concentration camps, KL Warschau had a less sophisticated internal structure.{{Sfn|Kopka|2007|p=84, 89}} Bogusław Kopka writes that the camp lacked the political department (''[[Politische Abteilung]]''), and some other positions remained unoccupied. Conversely, the [[Institute of National Remembrance]]'s report on the investigation of the crimes committed in KL Warschau says that the ''Politische Abteilung'' did exist, but it was directly subordinate to the commandant of ''[[Sicherheitsdienst]]'' and ''[[Sicherheitspolizei]]'' in Warsaw, instead of being the main department of the camp's administration.<ref name=":12" /> Among the 208 identified members of the camp's administration,<ref name=":16">{{Cite web|last=Kozubal|first=Marek|date=2017-06-04|title=Śledztwo w sprawie obozu zagłady w Warszawie umorzone|url=https://www.rp.pl/historia/art10419881-sledztwo-w-sprawie-obozu-zaglady-w-warszawie-umorzone|url-status=live|access-date=2021-09-14|website=Rzeczpospolita|language=pl|archive-date=10 November 2021|archive-url=https://web.archive.org/web/20211110065646/https://www.rp.pl/historia/art10419881-sledztwo-w-sprawie-obozu-zaglady-w-warszawie-umorzone}}</ref> SS-{{Abbr|Uscharf|Unterscharführer}} Karl Leuckel was the director of the administrative department, SS-''[[Oberscharführer]]'' {{Interlanguage link|Franz Mielenz|lt=|pl}} was the ''[[Rapportführer]]'' and the person responsible for prisoner work management, while SS-{{Abbr|Hstuf|Hauptsturmführer}} {{Interlanguage link|Willy Jobst|lt=|pl}} and SS-{{Abbr|Hstuf|Hauptsturmführer}} {{Interlanguage link|Heinrich Schmitz|lt=|pl}} were camp doctors.{{Sfn|Kopka|2007|p=84, 89}} The camp's staff was subordinate to SS-WVHA, but it also was obliged to cooperate closely with the SS and police leader for the [[Warsaw District]] due to an agreement reached between the two SS institutions.<ref name=":12">{{Cite web|date=2017-01-23|title=Śledztwa zakończone wydaniem postanowienia o umorzeniu|trans-title=Discontinued investigations|url=https://warszawa.ipn.gov.pl/waw/sledztwa/sledztwa/oddzialowa-komisja-w-wa/31499,Sledztwa-zakonczone-wydaniem-postanowienia-o-umorzeniu.html|url-status=live|archive-url=https://web.archive.org/web/20170525172847/http://warszawa.ipn.gov.pl/waw/sledztwa/sledztwa/oddzialowa-komisja-w-wa/31499,Sledztwa-zakonczone-wydaniem-postanowienia-o-umorzeniu.html|archive-date=2017-05-25|access-date=2021-09-14|website=Institute of National Remembrance – Warsaw District|language=pl}}</ref> The coordination was particularly strong during the pacification that happened at the turn of 1943/44, which was targeted at the Polish population of the capital.{{Sfn|Kopka|2007|p=62-63, 120}}
Besides mass shootings and other killings, the majority of other deaths resulted from physical exhaustion and the [[typhus]] [[epidemic]]s. Dead bodies were either burned in crematoriums and open-air [[pyre]]s or were buried under blown-up buildings of the former Ghetto. At the same time, a groups of SS men wearing white coats would pose as medical workers in order to find and execute Jews still hiding in the ruins.
 
There were three concentration camp commandants ({{Langx|de|Lagerkommandant}}) in the course of the camp's history:{{Sfn|Kopka|2007|p=42}}
===Tunnel controversy===
* SS-''[[Obersturmbannführer]]'' [[Wilhelm Göcke]] served until September 1943, when he was transferred to the newly created [[Kauen concentration camp|concentration camp in Kaunas]] in [[Generalbezirk Litauen]];<ref name="USHMM" />
* SS-''[[Hauptsturmführer]]'' [[Nikolaus Herbet]] commanded the camp from September<ref name="USHMM" /> or October 1943{{Sfn|Kopka|2007|p=42}} until his arrest in late April 1944;
* SS-''[[Obersturmführer]]'' [[Wilhelm Ruppert|Friedrich Wilhelm Ruppert]] was appointed in May 1944 and dismissed in late June the same year.
 
As for the ''[[Schutzhaftlagerführer]]'', who was simultaneously the camp director and the chief of the guards, SS-''Obersturmführer'' {{Interlanguage link|Wilhelm Härtel|lt=|pl}} served in this role from {{Langx|de|KL Warschau|label=none|italic=unset}}'s creation until his arrest in late April 1944, while SS-''[[Unterscharführer]]'' {{Interlanguage link|Heinz Villain|lt=|pl}} occupied the position for the remainder of the camp's existence.{{Sfn|Kopka|2007|p=88-89}}
An extremely controversial fact remains the existence of an enormous gas chamber in the pre-existing [[tunnel]] on Bem Street near the Warszawa Zachodnia train station. The tunnel was 630 square meters high, large enough to kill up to 1,000 people at a time; the Nazi gas chambers were typically smaller and lower, and using a big tunnel as a gas chamber would be highly irregular and inefficient. It is unknown if Zyklon B or [[carbon monoxide]] was used in this case. The tunnel was restored to street [[traffic]] after the war, and the alleged gassing [[pump]]s and connected massive [[ventilator]]s destroyed during a renovation works in 1996 and early 2000s.
 
The Warsaw concentration camp usually featured SS officers who were deemed to be low-value workers.{{Sfn|Kopka|2007|p=86, 89}} The first two commandants exhibited incompetence and little interest in the functioning of the camp.{{Sfn|Kopka|2007|p=85-86}} Many of the ''Volksdeutsche'' were hardly able to speak German, while some were [[illiterate]].{{Sfn|Kopka|2007|p=86, 89}} [[Corruption]] was rampant and extended up to the apex of the camp's hierarchy,<ref name=":9">{{Cite web|last1=Vági|first1=Zoltán|last2=Kádár|first2=Gábor|date=2019-11-14|title=From the Ghetto Revolt to the Warsaw Uprising – Hungarian Jews in KL Warschau|url=https://blog.ehri-project.eu/2019/11/14/hungarian-jews-in-warsaw/|url-status=live|access-date=2021-11-14|website=[[European Holocaust Research Infrastructure]] Project – Document Blog|language=en-GB|archive-date=14 November 2021|archive-url=https://web.archive.org/web/20211114143655/https://blog.ehri-project.eu/2019/11/14/hungarian-jews-in-warsaw/}}</ref> which Andreas Mix attributes to the fact that like the senior SS officers, the [[kapo]]s were Germans, therefore, the SS officers frequently made illicit agreements with them.<ref name=":13">{{Cite journal|last=Mix|first=Andreas|date=2005|title=Arbeitslager Warschau jako filia obozu koncentracyjnego na Majdanku|journal=Zeszyty Majdanka|volume=23|pages=55–70}}</ref> The irregularities were so numerous that SS authorities eventually intervened.{{Sfn|Kopka|2007|p=86-88}} Mix suggests an escape of a ''Reichsdeutsche'' prisoner triggered this intervention.<ref name=":13" />
The now hotly-disputed controversy not publicily debated and almost completely unknown during the era of the [[Polish People's Republic|communist rule in Poland]]. One of the possible reasons behind this secrecy was to increase the number of the perceived victims in the [[Warsaw Uprising]]; this uprising was initiated by the non-communist [[Polish Home Army]] against the Germans in August 1944, resulting in a massive number of civilian casualties. In 2001 the Polish [[Sejm]] appealed for building the [[memorial]]; in the meantime, a part of the tunnel was turned into an unofficial [[mausoleum]] by citiziens of Warsaw.
 
In late April 1944, Commandant Nikolaus Herbet, ''Schutzhaftlagerführer'' Wilhelm Härtel as well as ''[[Lagerälteste]]'' (camp supervisor) {{Interlanguage link|Walter Wawrzyniak|lt=|pl}}, were all arrested. The whole command of the camp was dissolved and almost all of its members were relieved of duty.{{Sfn|Kopka|2007|p=86-88}} By early May, the guards who were until then performing their duties in Warsaw were transported to [[Sachsenhausen]] and were replaced by personnel delegated from Majdanek.<ref name=":12" /> This scandal coincided with the degradation of the status of {{Langx|de|KL Warschau|label=none|italic=unset}} to a [[Subcamp (SS)|subcamp]] of [[Majdanek]] on 1 May 1944, and was thus renamed "[[Lublin]] concentration camp – Warsaw labour camp".<ref name="USHMM" />{{sfn|Kopka|2007|p=42}} According to some sources, it came due to deportations of prisoners to other camps as well as the [[Operation Bagration|advances of the Soviet army towards the territory of the General Government]].<ref name="Pohl" /><ref>{{cite book|last1=Poprzeczny|first1=Joseph|title=Odilo Globocnik, Hitler's Man in the East|date=2004|publisher=McFarland|isbn=978-0-7864-1625-7|pages=[https://books.google.com/books?id=NAIyBgAAQBAJ&pg=PA223 222–223]|language=en}}</ref> Bogusław Kopka, Andreas Mix and Paweł Wieczorek write, however, that it was the corruption scandal that was the causative agent for the change in status, though, as the former two historians say, the camp's reorganisation failed to get rid of the corruption issues.<ref name=":13" /><ref name=":11" />{{sfn|Kopka|2007|pp=87–88}}
In 2002 Sejm rejected the inconclusive findings of the IPN investigation. The new IPN investigation started in 2006 and is excepted to end in 2007.
 
=== Prisoners ===
==Liquidation and liberation==
 
==== General information ====
On [[July 20]] [[1943]] ''SS-Obergruppenführer'' [[Wilhelm Koppe]] ordered the complex to be liquidated and dismantled. The majority of prisoners were either executed or were transferred to other concentration camps, such as [[Dachau concentration camp|Dachau]], [[Gross-Rosen concentration camp|Gross-Rosen]] and [[Ravensbrück concentration camp|Ravensbrück]]. Between [[July 28]] and [[July 31]] four major railway transports left Warsaw, containing some 12,300 prisoners. A small group of several hundred inmates, mostly Jews from [[Europe]]an countries, were left in Pawiak and Gęsiówka to assist with the destruction of evidence; they were ordered to dig up and burn bodies. The camp's documentation was burnt, and the railway tunnel and the prison were mined for [[demolition]].
The trait that distinguished the Warsaw concentration camp from the other ones was that, with the exception of the initial transport of 300 Germans, the inmates were uniformly [[Jewish]].<ref name=":17">{{Cite journal|last=Rajca|first=Czesław|date=1976|title=Podobozy Majdanka|journal=Zeszyty Majdanka|volume=IX|issn=0514-7409|language=pl}}</ref> Additionally, {{Langx|de|KL Warschau|label=none|italic=unset}} only accepted prisoners who were previously in concentration camps under the jurisdiction of SS-WVHA; in contrast, it did not accept those prisoners who were to serve in concentration camps due to a decision of the [[Reich Security Main Office]] (RSHA), local [[Sicherheitspolizei|Security Police]] outposts, or new prisoners.<ref name=":13" /> These were predominantly young males (under 40 years old), whom the Germans deemed to be suitable for demanding physical work.{{Sfn|Kopka|2007|p=53}} Only in the last days of the camp's existence was a group of Jewish women from the nearby Pawiak prison delivered to {{Langx|de|KL Warschau|label=none|italic=unset}}.<ref name="USHMM" /> The Nazis were trying to transport Jews from various European countries and specifically sought to exclude Polish-speaking Jews, hoping that the lack of knowledge of Polish would prevent them from communicating with the residents of Warsaw.<ref name=":10">{{Cite book|last=Finder|first=Gabriel N.|url=https://www.jstor.org/stable/j.ctv4cbg9j|title=The Shtetl: Myth and Reality|date=2004|publisher=Liverpool University Press|isbn=9781874774754|series=Polin: Studies in Polish Jewry|volume=17|pages=325–352|language=en|chapter=Jewish Prisoner Labour in Warsaw After the Ghetto Uprising, 1943–1944|doi=10.2307/j.ctv4cbg9j.27|jstor=j.ctv4cbg9j|access-date=2021-09-13|archive-date=14 September 2021|archive-url=https://web.archive.org/web/20210914151650/https://www.jstor.org/stable/j.ctv4cbg9j|url-status=live}}</ref><ref name=":8">{{Cite journal|last=Rutkowski|first=Adam|date=1993|title=Le camp de concentration pour Juifs à Varsovie (19 juillet 1943–5 août 1944)|url=https://www.cairn.info/revue-le-monde-juif-1993-2-page-189.htm#re1no15|journal=Le Monde Juif|volume=147–148|language=fr|issue=147–148|pages=189–216|doi=10.3917/lmj.212.0189 |via=[[Cairn.info]]|access-date=10 November 2021|archive-date=10 November 2021|archive-url=https://web.archive.org/web/20211110070013/https://www.cairn.info/revue-le-monde-juif-1993-2-page-189.htm#re1no15|url-status=live}}</ref><ref name=":1">{{Cite journal|last=Zezza|first=Stefania|date=2021-06-30|title=Without a compass: Salonikan Jews in Nazi Concentration Camps and later|url=https://czasopisma.uni.lodz.pl/esrap/article/view/9126|journal=European Spatial Research and Policy|language=en|volume=28|issue=1|pages=45–71|doi=10.18778/1231-1952.28.1.03|s2cid=242441445|issn=1896-1525|access-date=14 November 2021|archive-date=14 November 2021|archive-url=https://web.archive.org/web/20211114143655/https://czasopisma.uni.lodz.pl/esrap/article/view/9126|url-status=live|doi-access=free|hdl=11089/39577|hdl-access=free}}</ref> Therefore, few Polish Jews were detained at the Warsaw concentration camp.<ref name=":8" />

The first transport of Jewish prisoners arrived from [[Auschwitz-Birkenau]] on 31 August 1943, and three subsequent ones were made up to 27 November the same year, bringing 3,683 Jews in total, according to official data.{{Sfn|Berenstein|Rutkowski|1967|p=8}} The labourers represented Jews from various countries – the most numerous were [[Greeks|Greek]] [[History of the Jews in Thessaloniki|Salonican Jews]],<ref>{{cite journal|last=Zezza|first=Stefania|date=2016|title=In Their Own Voices|url=https://www.eupsycho.com/index.php/TM/article/viewFile/135/119|journal=Trauma and Memory|volume=4|issue=3|pages=90–118|access-date=10 November 2021|archive-date=14 September 2021|archive-url=https://web.archive.org/web/20210914152315/http://www.eupsycho.com/index.php/TM/article/viewFile/135/119|url-status=live}}</ref> but some [[Austrian Jews|Austrian]], [[Belgian Jews|Belgian]], [[French Jews|French]], [[Dutch jews|Dutch]], [[German Jews|German]] and even 50 [[Polish jews|Polish]] representatives of that religion (who only came because Germans had to meet 1,000 people transport quota) arrived to Warsaw as well.<ref name="Kossoy">{{cite journal|last=Kossoy|first=Edward|author-link=Edward Kossoy|date=2004|title=The Gesiówka Story: A Little Known Page of Jewish Fighting History|url=https://gesiowka.adactio.com/|url-status=live|journal=Yad Vashem Studies|volume=32|pages=323–350|archive-url=https://web.archive.org/web/20210411033124/https://gesiowka.adactio.com/|archive-date=11 April 2021|access-date=6 September 2021}}</ref><ref name=":8" /> The ethnic composition changed substantially in spring 1944, when several trains from Auschwitz delivered {{Circa}} 3,000 [[Hungarian Jews]] (most of whom originally were deported from ghettos in [[Mukachevo]], [[Uzhhorod]], [[Khust]] and [[Tiachiv]], then in [[Carpathian Ruthenia during World War II|Hungarian-occupied]] [[Carpathian Ruthenia]])<ref name=":9" /> who became the majority in the Warsaw concentration camp in the last months of its existence.<ref name=":10" />
On [[August 5]] [[1944]] the assault group of Polish Home Army (AK) stormed the Gęsiówka camp located in the former Warsaw Ghetto and set free the remaining 360 men and women. Later, these survivors fought in the uprising. On [[August 21]], [[1944]], after the failure of an insurgent attack on Pawiak, its remaining prisoners were executed and the building was blown up by the Germans.

According to the [[United States|U.S.]] [[Holocaust Memorial Museum]] website, the remains of the Warsaw concentration camp were liberated in January [[1945]] by the [[Soviet]] troops. However, it's unlikely there were any live prisoners left at this time.
The exact number of prisoners who went through KL Warschau remains difficult to ascertain, as witness and expert estimates vary from 1,500 to 40,000.{{Sfn|Kopka|2007|p=54}} As [[Gabriel N. Finder]] noted, the Warsaw concentration camp played a minor role in the [[Holocaust]] in comparison to other camps and is thus often absent from standard narratives of the period.<ref name=":10" /> In his entry in the ''Encyclopedia of Camps and Ghettos'', he suggested that some 8,000–9,000 people were incarcerated there.<ref name="USHMM" /> Bogusław Kopka says in his monograph that at least 7,250 inmates went through the Warsaw concentration camp, including 300 German prisoner functionaries, about 3,700 Jews who arrived in 1943 and 3,000 Jews who came in 1944 from Auschwitz, in addition to 50 highly skilled Jews sent to the camp by the [[Ostbahn (General Government)|Ostbahn]] railway company in 1943 and 200 Jews moved from the Pawiak prison.{{Sfn|Kopka|2007|p=54}} Successful escapes were rare and Jews who were caught in the attempt were hanged in front of the assembled prisoner population.<ref name="USHMM" />
 
===Communist= prisonTasks camp====
Prisoners were tasked with constructing the concentration camp they were residing in, demolishing the remaining ruins of the ghetto, clearing {{convert|2640000|m3|ft3|abbr=on}} of rubble and with flattening the terrain at {{convert|1.20|m|ft|abbr=on}} above the previous ground level, so as to convert the former ghetto into a park as Himmler envisaged in his order from 11 June 1943.{{Sfn|Berenstein|Rutkowski|1967|p=6}}<ref name=":8" /> While doing that, the workers were also ordered to salvage building materials (mainly scrap metal and bricks) for the German war effort. {{convert|10000000|m2|ft2|abbr=on}} of buildings were demolished, which yielded some 8,105 tonnes of metal (of which about 7,300 tonnes of ferrous scrap metals and 805 tonnes of non-ferrous metals) and 34 million bricks.<ref name="USHMM" /><ref name=":17" /> A separate search team was formed to find whatever precious items, such as money or jewellery, were left in the ruins; yet another team was working on the ''[[Umschlagplatz]]'' near {{Interlanguage link|ulica Stawki w Warszawie|lt=Stawki|pl}} street, where salvaged items were sorted and stored in warehouses.<ref name=":17" /><ref name=":8" />
 
Tatiana Berenstein and Adam Rutkowski estimate the value of the pre-war houses demolished at 220 million pre-war [[Polish zloty|zlotys]] (i.e. slightly above [[US$]]800 million in 2021 dollars),{{Sfn|Berenstein|Rutkowski|1967|p=6}} but, according to Andreas Mix, the salvaged materials were only worth 5 million [[Reichsmark]]s, thus, with the initial investment of 150 million Reichsmark, the camp ran at steep losses.<ref name=":9" />
After the Soviet takeover in January [[1945]], the camp continued to operate as a [[prison camp]] for former AK fighters and other "enemies of the people's power" under the Soviet [[NKVD]] and then Polish [[Ministry of Public Security of Poland|MBP]] until [[1954]].
 
A couple thousand Polish civilians, who were paid, also worked in the area, as did dozens of German technicians.{{Sfn|Berenstein|Rutkowski|1967|p=11}}<ref name=":8" /> At one period, these people, who usually handled more sophisticated tasks, such as the maintenance of demolition machines and handling explosives, outnumbered the inmates. German constructions companies, including Berlinisches Baugeschäft ([[Berlin]]), Willy Keymer (Warsaw), Merckle ([[Ostrów Wielkopolski]]), and Ostdeutscher Tiefbau ([[Naumburg]]), operated there on contract and benefitted from slave labour provided by the prisoners.{{Sfn|Berenstein|Rutkowski|1967|p=7}} The Ostbahn assisted them.<ref name="USHMM" />

The conditions in {{Langx|de|KL Warschau|label=none|italic=unset}} were extremely harsh. Prisoners' food rationing was meagre and hunger was common among the inmates, which was exacerbated by lack of food parcels from the outside, as these were not delivered to the camp.<ref name=":10" /><ref name=":17" /> The shortages, however, were somewhat alleviated by the presence of Polish workers contracted to remove the ruins of the ghetto, as this was an opportunity for the inmates to clandestinely buy food for whatever valuables they could find in the ruins, and, in later days, when such items became scarce, for [[Gold teeth|gold fillings]] extracted from their teeth.<ref name="USHMM" /> However, the gold contained there was also of interest of the SS guards, who strictly forbade removal of the teeth. They sought to [[Nazi dental gold|enrich themselves by getting the precious metal]] after the death of the labourers.{{Sfn|Berenstein|Rutkowski|1967|p=6}}<ref name=":10" />

The Jews were subjected to [[extermination through labour]]. The demolition and salvage work were hard and perilous labor, carried out at a brisk pace with no regard to loss of life of the prisoners, so fatal workplace incidents were commonplace. The guards were torturing and murdering the Jews on a whim, viewing them as enemies of the state, and prisoner functionaries, particularly criminal prisoners, were hardly better in their treatment of fellow inmates.<ref name="USHMM" />{{Sfn|Kopka|2007|pp=63, 89–91}} [[Sanitation]] was sorely lacking to the extent that hungry and drained prisoners were decimated by outbreaks of infectious diseases, and the lack of [[hygiene]] gave way to infestations of [[lice]] and [[flea]]s.<ref name=":8" /> In particular, a typhus epidemic in January and February 1944 decreased the prison population by two-thirds,<ref name="Kossoy" /><ref name="USHMM" /> though the sanitary situation improved somewhat by the time the leadership was changed and the camp's construction was finished.<ref name=":13" /> The camp infirmary, according to Felician Loth, was "a parody of a sick ward",<ref name="Kombatanci" /> and patients who were unable to continue work were usually killed.{{Sfn|Bartoszewski|1970|p=234}} For these reasons, almost 75% of original prisoners have died by March 1944, reducing the camp's population to around 1,000 inmates.<ref name="USHMM" /> This prompted the Germans to supply about 3,000 Hungarian Jews from [[Auschwitz]].<ref name="USHMM" />

Just as the Jews in other concentration camps, the inmates in {{Langx|de|KL Warschau|label=none|italic=unset}} were forced to wear {{Interlanguage link|Pasiak|lt=camp uniforms|pl}} and wooden [[clog]]s. The former had the [[Star of David]] badge sewn on it and a Latin letter marking the inmate's provenance.{{Sfn|Bartoszewski|1970|p=235}} The newly arrived prisoners had their hair cut shortly and then underwent a procedure of bathing and [[wikt:disinsectization|disinsectisation]], which, before the bathhouse was built in the camp, was happening in Pawiak prison. Prisoner functionaries, however, were treated differently – they lived in a separate barrack (with the exception of the {{Langx|de|Blockältester|label=none}}), could wear civilian clothes, bear arms, and were even sometimes allowed to go outside the camp's premises.<ref name=":13" /> Jewish inmates speaking German and/or Polish also had slightly better conditions, the former because they could easily understand the guards' orders and communicate with them, while the latter could barter more efficiently with the Polish workers.<ref name=":10" />

In 1943–1944, camp inmates, Polish Jews caught hiding on the "Aryan side" of Warsaw or in the ghetto's ruins, Polish [[political prisoner]]s ([[Pawiak]] inmates) and Polish [[hostage]]s captured during the [[Roundup (history)|street roundups]] (''[[Łapanka|łapanki]]'') were executed in the ruins of the former ghetto, which surrounded the camp.{{Sfn|Engelking|Leociak|2013}} These executions took place almost daily and on some days, the number of victims reached dozens or even hundreds.{{Sfn|Bartoszewski|1970|pp=441–442}}{{Sfn|Domańska|1978|pp=27–28}} The bodies were then burnt, first in open air pyres and later in the camp's crematorium.{{Sfn|Kopka|2007|pp=26–27, 60–63, 120}}
 
The ruins of the ghetto supplanted previous execution sites, which were operating in the countryside around Warsaw, such as in [[Kampinos Forest]] (the site of the [[Palmiry massacre]]). The proximity of the Pawiak prison and the isolation of the former ghetto from the rest of the city, made them – from the German perspective – a far more suitable place for mass killings.{{Sfn|Bartoszewski|1970|p=256}} Members of {{Langx|de|KL Warschau|label=none|italic=unset}} personnel, along with the members of other SS and ''[[Ordnungspolizei]]'' formations in Warsaw, were among the executioners. Furthermore, a special ''[[Sonderkommando]]'', composed of the Jewish prisoners of the {{Langx|de|KL Warschau|label=none|italic=unset}}, was used to dispose the bodies of the victims.{{Sfn|Kopka|2007|pp=26–27, 60–63, 120}} The members of that detachment were often murdered after completing the task, too.{{Sfn|Szarota|2014|p=364}}

In summer 1944, as the [[Red Army]] [[Operation Bagration|was approaching]], the Germans decided to evacuate the prisons and camps in Warsaw. By the end of July, ''Schutzhaftlagerführer'' Heinz Villain demanded that all prisoners who would not be able to endure a march to assemble, promising the sick and exhausted that they would be transported in horse carriages. However, on 27 July, all those who appeared on the camp director's call were shot. The same day, all patients in the camp's infirmary were also killed. In total, around 400 prisoners, including at least 180 Hungarians, died due to these actions.<ref name=":9" />{{Sfn|Kopka|2007|pp=55–56}}
 
The evacuation of the Warsaw concentration camp started on 28 July. About 4,500 inmates were then forced to march to [[Kutno]], {{convert|120|km|mi|abbr=on}} away, in sweltering heat. During the march, which lasted for three days, the prisoners were not given water nor food; the guards additionally murdered everyone who was unable to proceed or who was too slow to execute orders.{{Sfn|Kopka|2007|pp=55–56}} Those who survived were loaded in freight carriages on 2 August, where poor conditions and the guards' cruelty added to the tally of dead prisoners. A total of 3,954 prisoners eventually arrived at the [[Dachau concentration camp]] on 6 August,<ref name=":10" /> of which there were only 280 Greek Jews who arrived at the beginning of the camp's existence.<ref name=":1" /> The ''Encyclopedia of Camps and Ghettos'' says that at least 500 inmates died during the operation,<ref name="USHMM" /> while Kopka gives a higher estimate of approximately 2,000 prisoners.{{Sfn|Kopka|2007|pp=55–56}} Most of the prisoners were subsequently transported to Dachau's subcamps in [[Mühldorf concentration camp complex|Mühldorf]], [[Kaufering concentration camp complex|Kaufering]] and [[Allach concentration camp|Allach-Karlsfeld]], while a few were sent to [[Flossenbürg concentration camp|Flossenbürg]]'s subcamp in [[Leitmeritz concentration camp|Leitmeritz]] (today's [[Litoměřice]] in the [[Czech Republic]]).<ref name=":1" />
 
The Warsaw concentration camp was still operating, however. Ninety SS personnel stayed there, as did about 400 prisoners who volunteered to stay in the camp to demolish it.{{Sfn|Szarota|2014|p=364}} Among those were about 300 original prisoners<ref name=":10" /> as well as dozens of Jewish prisoners of Pawiak (38–100 people, including 24 women), who were moved to {{Langx|de|KL Warschau|label=none|italic=unset}} on 28 July.<ref name="USHMM" />{{Sfn|Kopka|2007|p=49}}
 
On 1 August, the [[Home Army]] (AK) started an [[Warsaw Uprising|uprising against Germans in Warsaw]]. In the first day of fighting, the ''[[Kedyw]]'' (sabotage command) for the [[Home Army]] [[District of Warsaw (of Armia Krajowa)|District of Warsaw]] led by [[Lieutenant (Poland)|Lt.]] {{Interlanguage link|Stanisław Janusz Sosabowski|lt=Stanisław Janusz Sosabowski|pl}} "Stasinek" (son of [[Stanisław Sosabowski]]) captured Waffen-SS warehouses on Stawki street (''Umschlagplatz'') and a school on nearby {{Interlanguage link|ulica Niska w Warszawie|lt=Niska|pl}} street, setting free around 50 {{Langx|de|KL Warschau|label=none|italic=unset}} prisoners who were working there.{{Sfn|Szarota|2014|p=364}}{{Sfn|Bartoszewski|1970|p=236}} By that time, the Home Army also partially controlled the area of "the new camp", located near Okopowa street. In light of these advances by AK, the concentration camp's staff and the prisoners retreated to the fortified defence positions in "the old camp".{{Sfn|Borkiewicz-Celińska|1990|p=560}}
 
In the following few days, the patrol of the insurgent forces made several incursions into {{Langx|de|KL Warschau|label=none|italic=unset}}, with little success.{{Sfn|Borkiewicz-Celińska|1990|pp=567–568}} Meanwhile, [[Captain (armed forces)|Cpt.]] {{Interlanguage link|Jan Kajus Andrzejewski|lt=Jan Kajus Andrzejewski|pl}} "Jan", head of the {{Interlanguage link|Brygada Dywersji Broda 53|lt=Diversionary Brigade ''Broda 53''|pl}}, asked his superior, [[Lt. Col.]] [[Jan Mazurkiewicz]] "Radosław", to storm the buildings of Gęsiówka. Control over the concentration camp's area was important from a tactical standpoint, as the Home Army could gain control over the road leading to the [[Warsaw Old Town|Old Town]] via the ghetto's ruins, while also serving a humanitarian purpose of liberating the prisoners, who could be murdered.<ref name=":8" />{{Sfn|Borkiewicz-Celińska|1990|pp=571–572}} "Radosław" eventually agreed, and according to the plan, scout [[Battalion Zośka]] was handed the task of capturing the concentration camp's premises.{{Sfn|Borkiewicz-Celińska|1990|pp=571–572}}

== Postwar ==
 
After the retreat of the German forces from Warsaw, the former Nazi camp was first operated by the Soviet [[NKVD]] for German [[prisoners of war]], as well as for the soldiers of the Home Army loyal to the [[Polish government-in-exile]] and other persons suspected of opposing the Soviet occupation. As in the case for the German period, the prisoners were held in poor conditions and it is probable that numerous executions were taking place in the camp.{{Sfn|Kopka|2007|p=116}}
 
The camp was then turned over to the Polish [[Ministry of Public Security (Poland)|Ministry of Public Security]] (MBP) in mid-1945, when it became known as the Central Labour Camp for Warsaw's Reconstruction ({{Langx|pl|Centralny Obóz Pracy dla Odbudowy Warszawy|label=none}}). Its prisoners were used for construction and demolition works in the capital. Most of the prisoners of war were released in 1948 and 1949, and in November 1949 the labour camp was converted to a prison.{{Sfn|Łuszczyna|2017}} The facility, which became known under two names: Central Prison – Labour Centre in Warsaw ({{Langx|pl|Centralne Więzienie – Ośrodek Pracy w Warszawie|label=none}}) or Central Prison Warsaw II Gęsiówka ({{Langx|pl|Centralne Więzienie Warszawa II Gęsiówka|label=none}}),{{Sfn|Kopka|2007|p=116}} did not ''de facto'' change its purpose. The inmates were still producing building materials for [[History of Warsaw#Modern times|Warsaw's reconstruction]], and {{Langx|pl|Gęsiówka|label=none}} still used forced labour, but instead of prisoners of war, common criminals and people accused by the {{Interlanguage link|Komisja Specjalna do Walki z Nadużyciami i Szkodnictem Gospodarczym|lt=Special Commission for Fighting Abuse and Economic Sabotage|pl}} of economic wrongdoings were sent there.{{sfn|Kopka|2007|p=116}} According to Bogusław Kopka, 1,800 people died in the postwar prison;{{Sfn|Kopka|2019|pp=441–442}} though an estimate of 1,180 victims also appears in the literature.{{Sfn|Kopka|2019|pp=523, 525}} The fact that the former Nazi camp was taken and run by the communist authorities was the main reason why the [[Chief Commission for the Prosecution of Crimes against the Polish Nation|Chief Commission for the Investigation of German Crimes in Poland]] ceased its investigation in 1947.{{sfn|Kopka|2007|pp=19–20, 26, 51}}
 
The prison was closed in 1956 and was demolished in 1965. No element of the Nazi camp was preserved.{{sfn|Kopka|2007|p=52}} As of 2023, the site is occupied by a garden square, residential buildings, and the building of the [[POLIN Museum of the History of Polish Jews]].{{sfn|Kopka|2007|p=117}}
 
== Inquiries ==
[[File:Exhumation at the courtyard of Gęsiówka prison in Warsaw (1946).jpg|thumb|Exhumed bodies in Gęsiówka prison courtyard, part of Polish government's September 1946 inquiry into crimes committed in the camp]]
It did not take long for the newly established Communist government in Poland to start analysing the events that happened in the camp's history. Already in May 1945, the [[Chief Commission for the Prosecution of Crimes against the Polish Nation|Warsaw Circuit Commission for the Investigation of German Crimes in Poland]] launched a formal inquiry into the crimes committed in Warsaw concentration camp.{{Sfn|Kopka|2007|p=19}} Prosecutors inspected the premises several times, which yielded rich photographic documentation of the camp's buildings.{{Sfn|Kopka|2007|pp=26, 52, 66, 149–156, 160–163, 180–181, 609–620}} On 15–25 September 1946, a total of 2180&nbsp;kg of human corpses was exhumed and analysed (the corpses were then buried again in {{Interlanguage link|Cmentarz Wolski w Warszawie|lt=Wola Cemetery|pl}}); however, the exhumations did not cover the whole territory of the camp.<ref name=":12" />{{Sfn|Kopka|2007|pp=51–52}}
 
In 1947, the inquiry was halted for the first time due to political considerations, as the former concentration camp was functioning converted to a labour camp under the Communist [[Ministry of Public Security (Poland)|Ministry of Public Security]].{{Sfn|Kopka|2007|pp=19–20, 26, 51}} It was only in 1974 that the investigation was continued on the request of the [[Central Office of the State Justice Administrations for the Investigation of National Socialist Crimes]] in [[Ludwigsburg]], [[Germany]]; however, after two years, it was again suspended as the prosecutors deemed it impossible to retrieve more evidence in Poland. The investigation was once again opened in 1986, only to be closed in 1996 due to the unavailability of the perpetrators for interrogation (who either went missing or were already dead). A parallel inquiry by German federal officials was also closed.{{Sfn|Kopka|2007|pp=20–22}}
 
The topic of the camp returned to prominence in early 2000s, not least due to the July 2001 [[Sejm]] resolution commemorating the victims of the concentration camp,<ref name=":6" /> so the Regional Prosecutor's Office in Warsaw decided to open the Warsaw concentration camp case once again in 2002.<ref name=":32">{{Cite web|last=Kochanowski|first=Jerzy|date=2007-11-17|title=Śmierć w Warschau|url=https://www.polityka.pl/tygodnikpolityka/historia/235510,1,smierc-wwarschau.read|url-status=live|access-date=2021-09-11|website=[[Polityka]]|language=pl|archive-date=13 November 2021|archive-url=https://web.archive.org/web/20211113102323/https://www.polityka.pl/tygodnikpolityka/historia/235510,1,smierc-wwarschau.read}}</ref> The case was first managed by the Institute of National Remembrance's District Commission in Warsaw, then it was transferred to [[Łódź]],{{Sfn|Kopka|2007|p=22}} but was promptly returned to the capital.

=== Criminal responsibility of perpetrators ===
Following [[Allies of World War II|Allied]] victory in World War II, some people related to the Warsaw concentration camp's history were convicted in criminal or military courts.
* 53 SS officers and prisoner functionaries were convicted by the judiciary of the [[Polish People's Republic]], who in most cases received relatively light sentences. Five SS officers from the camp were executed for their role in administering {{Langx|de|KL Warschau|label=none|italic=unset}}; seven died in prison and the rest was released in 1956 at the latest.<ref name="USHMM" />{{Sfn|Kopka|2007|pp=92–98}}

[[File:Briefmarke_Konzentrationslager.jpg|alt=A 1995 German stamp (worth 1 Deutschmark), printed on white paper. On top, the text in German reads "50th anniversary of the liberation of prisoners from the concentration camps".

Probably in the 1950s, a [[Tchorek plaques|Tchorek plaque]], which said that "in 1943–1944, Polish patriots were repeatedly shot to death and burnt by the Hitlerites in this building", was installed on a wall of the burnt-out Wołyń Caserns, specifically on the east wall, facing Zamenhof Street.

Commemoration efforts were renewed in July 2001, when the [[Sejm]], the lower house of the Polish parliament, adopted a resolution commemorating the victims of the concentration camp while calling to create a monument "in remembrance of thousands of Polish inhabitants of Warsaw who were murdered in the Warsaw concentration camp as part of the [[Pabst Plan|plan of annihilating the Capital City of Poland]], as well as murdered citizens of other nationalities: Jews, Greeks, [[Gypsies]], [[Belarusians]] and [[Italians|Italian]] officers".<ref name=":6">{{Cite web|title=UCHWAŁA Sejmu Rzeczypospolitej Polskiej z dnia 27 lipca 2001 r. w sprawie upamiętnienia ofiar Konzentrationslager Warschau|url=http://orka.sejm.gov.pl/proc3.nsf/uchwaly/3262_u.htm|url-status=live|access-date=2021-09-11|website=Chancellery of the Sejm|language=pl|archive-date=14 January 2021|archive-url=https://web.archive.org/web/20210114223604/http://orka.sejm.gov.pl/proc3.nsf/uchwaly/3262_u.htm}}</ref>

The resolution that initially allowed the monument's construction was cancelled in October 2009 after consultations with the [[Council for the Protection of Struggle and Martyrdom Sites]], a governmental body responsible for the preservation of sites of wartime persecution, and it was decided to place a new monument in the neighbourhood of [[Muranów]], on the site of what was then [[Serbia Prison, Warsaw|Serbia prison]], some {{convert|200|m|ft|abbr=on}} away from the walls of the actual concentration camp.<ref name=":14">{{Cite web|last=Pinkas|first=Aleksandra|date=2010-06-11|title=Sąd na pomnikiem KL Warschau|url=https://www.zw.com.pl/artykul/484849.html|url-status=live|access-date=2021-09-08|website=Życie Warszawy|language=pl|archive-date=12 November 2021|archive-url=https://web.archive.org/web/20211112234039/https://www.zw.com.pl/artykul/484849.html}}</ref><ref>{{Cite web|date=2009-10-22|title=Uchwała nr LXIII/1994/2009 z 22-10-2009|url=https://bip.warszawa.pl/NR/exeres/E22E0F69-6813-4600-AA08-48E55F27F756,frameless.htm|url-status=live|access-date=2021-09-14|website=[[Biuletyn Informacji Publicznej]] – Warsaw|language=pl|archive-date=12 November 2021|archive-url=https://web.archive.org/web/20211112234042/https://bip.warszawa.pl/NR/exeres/E22E0F69-6813-4600-AA08-48E55F27F756,frameless.htm}}</ref>{{efn|As of March 2022, the monument in Muranów has not yet appeared.}} That decision was opposed by supporters of Trzcińska's hypothesis, who argued that placing the monument there would suggest that only Jews were victims of the concentration camp, but the [[Supreme Administrative Court of Poland|Supreme Administrative Court]] denied their request to invalidate the new resolution.<ref name=":14" />
