A book published by Albert Váry in 1922, titled "The Victims of Red Terror in Hungary" documents 590 suspects executed by communist paramilitaries.

In the cases where Szamuely launched mass reprisals (e.g. István Bartalos, Tibor Bonyháti, Gábor Csomor, Péter Csoba, Imre Dögei, Géza Groó, Lipót Holtzmann, József Kakas, József Kuszkó, Márton Löscher, Ferenc Miákovics, Károly Pergovátz, Mihály Pervanger, Mihály Pintér ?

The infamous armoured train of Szamuely was often manned by terrorists belonging to the Cherny group, who thus took part in the suppression of all major real or imagined counter-revolutionary uprisings.

They reported the matter to Tibor Szamuelly, who was in Szombathely, and who arrived in Kőszeg with Otto Korvin Klein and his terrorists on 6 June 1919, where Dr. Halász, on the basis of the report of József Hirschler and others, sentenced him to death and - with his terrorists - immediately executed Jenő Waisbecker and György Heresies without any formality, with a simple wave of the hand.

After the Hungarian–Romanian War, Romanian Army troops entered Hungary and took Budapest on 6 August 1919, Kun and other members of the government fled.

After the arrival of Miklós Horthy's counter-revolutionary death squads in Budapest three months later, anti-communist officers carried out waves of retributive violence against communists and their supporters (as well as suspected leftists of any stripe) known as the White Terror, wherein as many as 1,000 people were killed.

[4] On 18 December 1919, the following 14 people were executed in the prison at 85 Margit Boulevard:[5] József Cserny, Sándor Papp, Ferenc Kakas, Sándor Mészáros, Gábor Schön, Max Miksa, Tibor Bonyháti, Géza Groó, Mór Löbl, Gábor Steomor, János Steiger, Márton Löscher, Lajos Küvér, Géza Neumayer.

The Hungarian Curia (Supreme Court) rejected one by one of the fourteen terrorist pardon requests and allowed free access to justice.

At the behest of the state prosecutor's office, the death sentences were carried out in the courtyard of the Margit Boulevard military prison on Thursday morning from 8 a.m. to noon.

Three criminal judges appeared at the execution: dr. Gyula Keresztessy, dr. Károly Gebhard and dr. Béla Nagy, also dr. Ferenc Szücs clerk.

On the afternoon of 17 December, Dr. Elemér Felföldy, the public prosecutor, announced the rejection decision of the court's pardon committee, and then placed all fourteen people on death in the prison, which had been converted into an execution house.
