Pretty much everything mentioned in your post they encountered. Also they were attacked one night and they said that St. Michael appeared and fought them off.

They didn't go into a lot of detail,but enough so you can read into it. This is the only fairly modern example of a society that sacrificed so many people. It was written about not long after the final battle......

They had a rack of skulls with over 100k heads on it. It's been several years since I read it,I would need to read it again to get more details.

They also said that a UFO was seen leaving after the final battle
