On May 21, 1945, a unit of the Polish Home Army (Armia Krajowa, AK), led by Colonel Edward Wasilewski, attacked a Soviet NKVD camp located in Rembertów in the eastern outskirts of Warsaw.

They imprisoned members of the Home Army, who were seen as enemy combatants due to their loyalty to the Polish government in exile.

They were not to be compared to the relative luxury at Sandbostel or Murnau" and throughout the winter of 1944–1945, "prisoners were frequently held in the open, without shelter, in a compound surrounded by barbed wire (...) According to the reports, when locals enquired about the suffering prisoners, who were clearly visible from a nearby road, they were told that the compound contained Volksdeutsche and Nazis".

Captain Walenty Suda ("Młot": hammer), the Home Army commander of Mińsk Mazowiecki District planned to attack the camp prior to the transport.

While disguised as a soldier of the Ludowe Wojsko Polskie (Polish Communist Army), Wasilewski reconnoitred the camp.

On the night of Saturday, May 20, 1945, the prisoners' relatives brought large quantities of alcohol to the camp to ensure the NKVD guards would become drunk.

The Polish Army unit travelled to Rembertów on horses from nearby Długa Kościelna village and then divided into three groups.

On the morning of Sunday, May 21, 1945, Soviet troops, supported by aircraft, combed the area around Rembertów in search of the escapees.

The text of the tablet on the monument reads: W miejscu tym na terenie dawnej fabryki "Pocisk" znajdowały się obozy od września 1941 do początku 1944 - hitlerowski obóz pracy jeńców sowieckich - komando stalag 333 - od lipca 1944 do września 1944 - hitlerowski obóz pracy dla więźniów polskich - od września 1944 do lipca 1945 sowiecki obóz specjalny NKWD nr 10.
