Philip Slier

 Philip ("Flip") Slier  (4 December 1923 – 9 April 1943) was a Jewish Dutch typesetter who lived in Amsterdam during the German occupation of the Netherlands in World War II. Slier left documentation of his experiences as a forced labourer in the Molengoot labor camp in a series of 86 letters that he wrote to his parents between April and September 1942. His family concealed his letters in their Amsterdam house, where they were discovered more than 50 years later.

Early life
Philip Slier (rhymes with "beer") was born on 4 December 1923 in Amsterdam, Netherlands, on the top floor in their third floor apartment at 128 Vrolik Street. To his friends and family, Philip was known as "Flip".

Demeanor and physical description
His best friend Karel van der Schaaf describes his demeanor as brutaal - an uninhibited, extremely daring and bold, but good-natured teenager with a sense of humor, who liked being around others. Deborah Slier, editor of reference book Hidden Letters and Flip's cousin, says his letters show him to be "likeable, optimistic, humorous, and affectionate." He had a musical inclination as he liked singing and he played the flute and mandolin. Another of his hobbies was photography, for which he had a passion.

As a teenager, he was "5 feet 7 3/4 inches tall, weighed 156 lbs, had black hair and gray eyes".

Teenage years
Flip’s first girlfriend, Truus Sant, played the drums in a musical band called the AJC band - "Arbeiders Jeugd Centrale" (Worker's Youth Center). He played the flute in the band. Flip’s parents did not approve of her because he was Jewish and she was Christian. The Germans invaded the Netherlands in 1940 when Flip was seventeen years old.

Road to death
On 23 April 1942, when Flip was eighteen years old, he received a notice with instructions to board a train to a labor camp. These instructions came from the Jewish Council of Amsterdam, who were complying with orders from the German occupiers, who threatened dire consequences (arrest) if the notice was ignored. He went to Camp Molengoot (English: "mill gutter") where he was forced to perform hard labor under harsh conditions. The camp was at Collendoorn, a small settlement just north of Hardenberg. The work was in digging a canal for a mill flume, a mill gutter. From Molengoot, Flip wrote to friends and his family almost daily, giving an eyewitness account of life in the camp with his dozens of letters. Camp Molengoot was to be closed and the prisoners were to be sent off to Westerbork transit camp (essentially a temporary detention holding area) on 3 October, Yom Kippur.

It is possible that Flip heard of the fate of the Jews in the camp (being death at another camp) and wrote his last letter on 14 September 1942 and then escaped from the camp. Flip went to Amsterdam. He was an onderduiker (literally "under-diver" - a person hiding from the Germans), and many times protected by others (i.e. farmers, families). Flip was offered protection and shelter by Karel van der Schaaf's brother, Jo. Jo lived only 2 blocks away from Flip's parents, who lived on Vrolik Street. He was able to visit his parents often using fake papers and changing his physical appearance.

Flip moved to different hiding locations in Amsterdam from time to time, as most onderduikers did to prevent detection by the Germans. Sometime around February 1943 Karel van der Scaaf (Flip's close friend) made arrangements with someone in Bussum or Hilversum for Flip's escape to Switzerland. However on 3 March 1943 Flip was caught and arrested by the Germans at the Amsterdam Centraal railway station when he was trying to board a train to Switzerland. It is unknown who may have told the Germans of Flip's escape plans, but the contact in Bussum (or Hilversum) was later considered "untrustworthy".



The given reason for Flip's arrest on the official arrest record was Ohne Stern ("without a star" - not wearing a yellow star badge on his outer clothing indicating he was a Jew, as was required by the Germans). He was apprehended and transported to Vught concentration camp in the southern Netherlands (North Brabant). A questionnaire for the prisoners indicated that Flip put up some resistance when he was apprehended to go to Vught, as it said he had scars on his lip.

The law set by the Germans during World War II in occupied Netherlands was that all Jews six years and older had to wear on the outer clothing a six pointed yellow star symbol for easy identification. It was to be the size of a saucer. The black lettering of "jood" had to be in the middle, which was the Dutch word for Jew. Punishment for not wearing one if you were a Jew was severe and could even be deportation to a concentration camp.

Flip's time at Vught concentration camp was very harsh conditions, as was reported for the treatment of all prisoners. The conditions were so bad that some prisoners thought that conditions in Poland could not be as bad as they were in Vught. One prisoner commented, ''Things surely can't be as bad in Poland as they are at Vught. It's hell, sheer hell!"'' Vught concentration camp, run by the SS, held 18,000 people, mostly Jews but also had some political and resistance prisoners.

Flip was transferred to Westerbork concentration camp on 31 March 1943, where he was put into a punishment barrack.

On 6 April 1943 Flip, with many of his friends and relatives, were loaded into a railroad cattle cars shipped from Westerbork to Sobibor extermination camp. There were 2020 prisoners shipped to Sobibor on Flip's train. They arrived at the extermination camp on 9 April 1943. Upon their arrival they were killed by gas.

Flip's parents were arrested on 24 May 1943 and transferred to Westerbork concentration camp. On 1 June 1943 they, along with 3,000 others, were loaded into railroad cattle cars for Poland to the Sobibor extermination camp. They were both killed on 4 June 1943.

Of the 58 immediate members of the Slier family in the Netherlands at the beginning of the war only 6 were alive at the end of the war. From the Netherlands less than 25% of Dutch Jews survived World War II.

Hidden letters
Flip wrote 86 letters (including postcards and a telegram) and since the publication of Hidden Letters more have been found. He wrote these letters to his family and to friends from the Dutch work camp Molengoot where he was taken. He sent letters on almost a daily basis from April to September 1942. They show an insight into the life at these work camps. Flip wished his letters to be saved and asked his parents to hide them away.

In 1997, the house at 128 Vrolik Street in Amsterdam where Flip had lived with his parents was being demolished. The foreman of the demolition company came upon Flip's letters hidden in the ceiling of the third floor bathroom. He found 86 letters and postcards plus a telegram. The foreman thought the papers could be important and kept them for two years. He then turned them over to the National Institute of War Documentation (NIOD: National Instituut voor Oorlogs Documentie, now called "Instituut voor oorlogs; holocaust and genocide studies"). He was hoping that eventually he would learn the fate of the boy who wrote the letters.

An expert on Anne Frank at NIOD could see the significance in Flip's letters and passed them onto a journalist. She published these hidden letters in an article on her own on the work camps in the Journal Vrij Nederland (where she worked). The hidden letters eventually came into the possession of Flip's cousin in 1999. She in turn did extensive research follow up and produced a book called Hidden Letters, which is a comprehensive study on Flip's letters.
