(CNN) -- An estimated 6 million Jews died at the hands of the Nazis and their allies during the Holocaust. Hundreds of thousands more suffered, but somehow survived, in concentration camps. And some escaped, savoring freedom they otherwise never would have known.
Then there's Ernst Hess, who was a decorated World War I soldier, former judge and, despite being raised a Protestant and marrying someone of that faith, a "full-blooded Jew" in the eyes of the Nazi regime.
According to a groundbreaking report, Hess was granted a reprieve despite this designation thanks to none other than Adolf Hitler.
Susanne Mauss, editor of the Jewish Voice from Germany newspaper, found the August 27, 1940, note from the Gestapo (the infamous Nazi secret police) that saved Hess -- albeit temporarily. The order was revoked the next year, and Hess spent years doing hard labor in Nazi concentration camps and work sites.
Still, given Hitler and his colleagues' extreme views and actions on Jews, even the temporary amnesty granted in the letter that Mauss unearthed in a file kept by the Gestapo in Dusseldorf about Hess is extraordinary.
Written by the notorious SS figure Heinrich Himmler, the note calls for saving and protecting Hess "as per the Fuhrer's wishes," referring to Hitler, who had led Germany since 1933.
The letter, a copy of which is posted on the Jewish Voice from Germany's website, also states that Hess should not be inconvenienced "in any way whatsoever."
Hitler and Hess had crossed paths before, serving in the same infantry unit during World War I. In fact, for a short time Hess had been Hitler's commander -- though the Jewish Voice from Germany said Hess, whose now 86-year-old daughter was interviewed for their story, didn't personally know Hitler and their fellow comrades described the future Nazi leader as quiet, with no friends in the regiment.
But Hess himself was close to many of his fellow veterans, including Fritz Wiedemann, according to daughter Ursula Hess. And Wiedemann, who became a top aide to Hitler from 1934 to 1939 before becoming Germany's consul in San Francisco through 1941, helped connect Hess to Hans Heinrich Lammers, the head of the Reich Chancellery during Hitler's reign.
Hess, who was forced to retire as a judge in 1936 -- the same year he was beaten up by special police in front of his home -- had pleaded for leniency before. According to the Jewish Voice, he had petitioned Hitler to make an exception because his daughter Ursula would be considered a "first-degree half-breed" under Nazi doctrine.
Highlighting his patriotism and Christian upbringing, Hess wrote, "For us, it is kind of spiritual death to now be branded as Jews and exposed to general attempt."
That appeal was denied, though the Hess family was able to move to a then German-speaking part of Italy for the next several years. In that time, Hess still got part of his military pension and his passport wasn't stamped with a red J to brand him as Jewish, the Jewish Voice reported.
But after a pact with Italy that ceded that area to the Nazi regime and the family's attempts to flee to Switzerland and Brazil failed, they landed back in Germany in 1940.
The reprieve, credited to the fuhrer, came in the summer of that year.
But in 1941, Hess submitted the letter of protection, only to have it swiped away. The special order revoked, he landed soon thereafter in a concentration camp, and then began working for a timber processing company helping build barracks for Nazi soldiers.
"The slave workers were forced to live outdoors and were treated terribly, and of course they were watched by members of the SS," said Ursula Hess of her father, who besides being a soldier, judge and "sportsman," had once been a concert violinist. "Had he not been as fit as he was, he would never have survived."
The name Hess is well established in German 20th-century history. A man also named Ernst Hess was one of Germany's ace fighter pilots during World War I, before being killed in action. Rudolf Hess was once Hitler's deputy, before flying to Scotland on an alleged peace mission in 1941 that instead ended with him becoming a prisoner of war.
Ernst Hess, though, was a prisoner of a very different sort through the early 1940s when Nazi authorities deemed him "a Jew like no other."
When the war ended and he gained his freedom, according to the Jewish Voice report, Hess was asked to become a judge yet again. He turned down the offer. A year later, Hess launched a new career and gained new prominence as a railway executive.
By then, he'd rejoined his wife and daughter. But not all his family: His sister Berta was killed in 1942 in the Auschwitz concentration camp.
