Nope, standard part of the narrative. I learned it in school nearly 20 years ago.
Apparently, Hitler was concerned that his and Eva Braun's corpses would be defiled like Mussolini and his woman's had been previously.
See: https://en.wikipedia.org/wiki/Death_of_Adolf_Hitler#Suicide
>In accordance with Hitler's prior written and verbal instructions, the two bodies … were doused with petrol. … After the first attempts to ignite the petrol did not work, Linge went back inside the bunker and returned with a thick roll of papers. Bormann lit the papers and threw the torch onto the bodies … two corpses caught fire.
Not saying I necessarily believe it anymore, simply that this isn't an attempt to rewrite the history books.
