Four Kloostra Brothers in Dachau – The Fight Against Communism
| SPANISHSKY.DK 28 MARCH 2021 |
Dutch Anti-fascism and Anti-communism
Like many Dutch communists, four Kloostra brothers and three of their brothers-in-laws became victims of an anti-communist operation that started in January 1923 and was continued after the Dutch capitulation in May 1940 on orders from the burgomaster of The Hague. The 1923 operation was part of the late 1917 anti-communist activities of the Dutch Intelligence and Security Service.

The International Criminal Police Commission
With the primary purpose of fighting communism, the International Criminal Police Commission (ICPC) was founded in 1922. Known today as Interpol, the ICPC was a cooperative network of national police intelligence services.
Police Commissioner of Amsterdam, Karel Henri Broekhoff became the Dutch representative. The ICPC soon agreed upon a thorough infiltration of all communist parties. Broekhoff spearheaded the infiltration of communist parties in numerous Dutch cities; in The Hague the best-known informant was Johannes Hubertus van Soolingen who turned many communists in to the Dutch Intelligence and Security Service.
By 1935 a fundamental nazification of the ICPC had taken place. The Dutch Minister of Justice, Josef van Schaik, instructed Broekhoff to start a collaboration with the Gestapo branch of the Reichssicherheitshauptamt (‘Reich Main Security Office’) in Berlin.
Collaboration with the Gestapo
The first meeting took place on the 4 and 5 January 1935 . Broekhoff collaborated with some of the leading architects of Holocaust, including Chief of the Gestapo, Heinrich Müller, who was responsible for the implementation of the genocide of Jews known as the Final Solution and consequently one of the biggest mass murderers of the 20th century.
Broekhoff also collaborated with Obergruppenführer of the Sicherheitsdienst, SD (SS and Nazi Party Security Service), Bruno Friedrich Wolff, who, in May 1940, was in charge of the fight against communism in the Netherlands. Wolff encouraged the use of violence against the arrested communists — an encouragement which sadist Ernst Knorr, inspector of the SD and Untersturmführer of the Schutzstaffel (SS), followed with great pleasure. In one case Knorr said to a communist to be tortured: ‘Singen mussen Sie’ – You will sing .
The collaboration translated into two lists (one in 1936 and one in 1939) of Dutch active communists which were handed over to the Gestapo causing the deaths of hundreds of Dutch communists. These lists were the direct reason the Gestapo caught on to Tjerk Kloostra – one of the four Kloostra brothers to whom this short series of articles is dedicated.
Anti-communist activities during the occupation
By 1938, Nazi-Germany’s objectives were obvious to most observers which makes it even more alarming that the Dutch Minister of Justice, Carel Goseling, in 1938 ordered the police—including the Intelligence and Security Service—to continue their activities in the likely scenario of a German occupation of the Netherlands . This order would eventually claim the lives of a thousand Dutch communists and send another thousand to concentration camps.
On 10 May 1940, Germany invaded the Netherlands. Five days later, 15 May 1940, the Dutch forces surrendered to Germany. On the very day of the capitulation and under the order of the Minister of Justice, the burgomaster of The Hague, Salomon Jean René de Monchy, ordered the municipal security service to continue their anti-communist activities. Informant van Soolingen was approached and requested to continue his infiltration of Communist Party of the Netherlands (CPN), which was being transformed into an underground resistance organisation .
The infiltration would cost the lives of about 100 communists from the region around The Hague (Leiden-Delft) and 40 communists from the region of Rotterdam. A comparable number survived prolonged internment in concentration camps. From existing material, we know of four arrest waves between 1941 and 1945, prompted by van Soolingen’s intelligence information .
The first arrest wave
The first arrest wave started on 28 April 1941 with the arrest of four communists by the Sicherheitsdienst to prevent the distribution of International Workers’ Day flyers. A report was sent to Berlin stating that about 40 more arrests were expected and showing which information was supplied by van Soolingen. Based on his information and information obtained during interrogations under torture between April and November 1941, over 150 communists were arrested by mixed units of German and Dutch security service officers.
The torture was also carried out by German and Dutch security service officers and a Dutch security service pre-war informant. Of the 150 arrested communists, 57 would die under their hands and 49 would spend a part of their imprisonment in the Dachau Concentration Camp . During the initial arrest roundup, four members of the Kloostra family were arrested: Jan Kloostra, Frederik Hendrik (Fred) Donderwinkel and Cor Rademaker, who died in 1942 in the Groß Rosen Concentration Camp.
Prompted by the German invasion in the Soviet Union, the Kloostra family’s brother-in-law Frans van den Berg was arrested by the Dutch Intelligence and Security Service 25 June 1941 and received the same treatment as those arrested in connection with the infiltration of the Dutch communist party.
Some communist escaped the repressive waves of persecution — at least for a while. Amongst them were Reinder Kloostra and Willem (Willy) Frederik Donderwinkel (brother-in-law) who were, however, eventually arrested.
2 September 1942, communist Herman Holstege was cruelly tortured to death by German and Dutch security service officers in the Scheveningen prison (nicknamed Oranjehotel – the Orange Hotel). When Knorr trust a truncheon up Holstege’s anus, fatally damaging his internal organs, his roar of pain resounded throughout the prison, leaving the inmates horrified .
Although it has later been claimed that Holstege only provided false information, the next two days two of his closest collaborators in Rotterdam were arrested. It is believed that the information he provided during torture and the subsequent house searches resulted in the arrest of about 180 communists, of whom 47 would be killed and 13 sent to the Dachau Concentration Camp .
The second arrest wave
The second wave took place in May 1942—mainly in Delft (South Holland)—during which about 80 communists were arrested of whom seven would be killed: two were executed and five succumbed to death in concentration camps. However, most of them were released. About 20 prisoners were sent to concentration camps, two of them to Dachau .
The third arrest wave
The third wave started in December 1942 with the arrest of the communist resistance leader in The Hague, Jacob (Jaap) Boekman, who fell into a trap set up by the Dutch Intelligence and Security Service with the aid of informant van Soolingen. Subsequently, over 40 communists would be arrested 15 of whom would be killed: seven by execution, seven in concentration camps and one, Tjerk Kloostra, was shot through the head by police officer Jochem de Graaf after a gunfight with the Dutch police 24 February 1943. Of the detainees, nine spent time in the Dachau Concentration Camp. Among those arrested were Johan Kloostra and his brother-in-law Willy Donderwinkel .
The fourth arrest wave
The fourth arrest wave took place on 9 March 1945. Four persons were arrested, of whom three were executed on the 12 March 1945. The detainee who escaped execution, a woman, was released a month later. Blissfully ignorant of the fact that he was a security service informant, she had been in close contact with van Soolingen. During interrogations, a Dutch security service officer accidentally revealed information which made her realise van Soolingen’s true identity. Due to her vigilance, the entire event could be reconstructed after the war.
After the war, a large square in The Hague was named after burgomaster De Monchy, who was responsible for the death of at least 130 communist resistance fighters.
Dutch historians have never carried out an in-depth investigation into the fate of the Dutch communist resistance fighters. There is evidence to suggest that the infiltration in The Hague, starting in 1923 and continued throughout the German occupation, took place in other parts of the Netherlands as well.
The full death toll from this political persecution and other involvements of the Dutch authorities in combatting communist resistance against Nazism probably amounts to thousands. It is estimated that the Dutch authorities are directly responsible for the deaths of approximately two thousand communist citizens, which accounts for about two-third of the total death count of communists.

 Biography by Johannes Hubertus van Soolingen in his pardon file, National Archives. In the biography, Soolingen confesses he had infiltrated the Hague CPN since January 1923 at the request of the Dutch Intelligence and Security Service and mentions that the Dutch Intelligence and Security Service approached him a few weeks after the German invasion with a request to continue the infiltration.
 Former prisoner in the Dachau Concentration Camp, Christiaan van Spronsen wrote in his 1979 application for a resistance pension that van Soolingen was in his resistance group in 1941, Stichting (Foundation) 1940-1945.
Johannes Hubertus Veefkind wrote in Vertrauliche Mitteilung über die illegale CPN in Den Haag (Confidential communication about the illegal CPN in The Hague) that van Soolingen informed him of an active group of communists in Delft: Special Criminal Procedures Central Archives (CABR) 107, file Veefkind, National Archives. This information led to the second communist arrest wave.
In the same file Veefkind reported that van Soolingen had informed him he had infiltrated the CPN again. This turned out to be with the involuntary help of Johannes Philippus Bronkhorst (former prisoner of the Dachau Concentration Camp). The information van Soolingen had gained and the information he obtained after the entrapment of the Jewish communist resistance leader Jacob Boekman led to the third arrest wave.
For information about the way van Soolingen lured Jacob Boekman into a trap cf. statements by Intelligence officers Cornelis Bakker, Cornelis Heijnis and Jilis van der Waard, respectively CABR 71245, 431 and 308.
Toward the end of 1944, van Soolingen infiltrated the CPN again, which led to the fourth arrest wave: Confession by van Soolingen in his files at CABR, files 76478 and 91269.
