Decoding the Holocaust.

In 2000, at the National Archive at Kew, in London, the best known decode about the Holocaust was found;

"Discovered in 2000 in our Government Code and Cypher School collections (HW) and arguably the most important find in the history of the Holocaust this century, this message was among many decrypts of German Police communications decoded at Bletchley Park during the Second World War. It is not known whether its significance was understood at the time."

"The Hoefle Telegram records the exact number of victims in the death camps of Majdanek, Belzec, Sobibor and Treblinka up to the end of 1942. It is a fortnightly statistical report of the arrivals at these camps, which were built for extermination purposes only following the decisions made at the Wannsee Conference in January 1942 by high-ranking Nazi officials. The plan to implement the destruction of European Jewry was known as Operation Reinhart.

(There is an error in recording the number sent to Treblinka, which is missing a digit)."

The significance of the telegram is that it shows how many people were transported to the AR camps. What other intercepts are there?

"By early 2004, at NARA, over 600 translations and
decrypts of various intercepted messages about
the Holocaust could be found in the record
groups of the National Security Agency. These
included some decrypts of German Police mes-
sages that reported the massacres of Jews and
other groups. Others are messages from mostly
diplomatic sources that bear witness to such
events as the roundup of Jews in Hungary and
other countries in occupied Europe."

The earliest transmissions included numbers being shot;

"The British records released so far show little concerning SIGINT from police traffic )>efore the invasion of Russia. Thereafter we have this sampling of dreadfulness, taken from police radio messages intercepted and
decrypted during July and August 1941:

Police Group
At Slonin, Regt South
Minsk area, SS Cavalry Brigade

Cipher
1,153 Jews shot
3,600 executed"

The Einsatzgruppen regularly updated Berlin as to what was happening, and intercepts as to their activity showed mass shootings. The French also intercepted messages;

"The French SIGINTservice element that had stayed behind in Vichy France intercepted
some 6,000 police messages and radioed both decrypts and traffic to the U.K. A French
decrypt of a 28August1941 police message from Russia reported that 5,130 Jews had been
shot that day by an SS Brigade, Police Regiment South and Police Battalion 320."

"SIGINT produced no clear information about the genocide in the death camps and
apparently nothing about the gassings. However, traffic in the readable Orange I Enigma
Key produced considerable, though misleading, information about the camps during 1942-
43. The British decrypted traftfo from some ten camps, including Auschwitz, identified_ in
the SS messages as ..Camp G." The GC&CS analysts determined that the unlabeled
columns in these messages probably gave a daily report showing number of inmates at the
beginning of the day, new arrivals, "departures by any means" and nationalities. But the
numbers, including those in the ominous "departures" columns, are relatively low. The
British Official History of Intelligence in World War II does not remark on this."

Nothing has been found that is so blatant, that it records mass gassings. Instead, mass shootings were recorded and the camps where mass gassings took place recorded mass arrivals and then drops in population.
