Harry, your film was not in the ground with humidity.
Books published to date... 'Belfast Diaries: A Gunner In Northern Ireland'... 'A Tough Nut To Crack - Andersonstown'... 'An Accrington Pal: The Diaries of Pte Jack Smallshaw, September 1914 To March 1919'.
IMO and knowledge I believe that IF the prevailing conditions were right such as cool to cold environment and the camera was in a "sealed" condition it is possible ~
on the flip side the reason for example that there are limited colour photos of the Pacific war was that the film needed to be kept cool and dry . Obviously the wet tropics is not conducive to film preservation !
I looked at the above links and see someone may have lied but from my own experience.
About 20 years ago I bought a box full of household items at a Farm/estate sale and a camera (Kodak box, if I remember correctly) was in it, and it had a roll of film in it (camera was beat up and had been wet as the leather ?? covering was peeling off). I know wet is a lot different than buried for 75 years with rain and snow. But nevertheless an old camera hobbiest friend developed the film with scenes probably from 30's - 40's and all were still visible except some on the end that were exposed when I opened it not knowing film was still in it. So I think it is possible, even tho this looks to be a fake. . Richard
Bit of a bummer that this turned out to be fake.
Someone from Gunboards recognized the rest of the pictures (the ones that were not of the GI with the pipe and .30 cal).
Here is the information (direct quote in his words): The first 4 pictures are in a book World War II A Photographic Record Of The War In Europe from D-Day to V-E Day it was published in 1962. (by ironhead69)
I'm sure someone found a camera, and maybe there was even some film in it, but it looks like the story is just that.
FAKE FAKE FAKE here are scans from the book published in '62
