Les grands cimetières sous la lune is a title of a book written by a person named Georges Bernanos. It is a book that talks about a very important moment in history, which happened a long time ago.
Imagine a big world where there are many countries, each with their own people, culture, and beliefs. Long ago, one of these countries was going through a difficult time. They were fighting against a group of people who had different beliefs and wanted to take over their country.
During this time, many people died in this country from violence, starvation, and disease. It was a sad and difficult time for the people living there.
After the fighting stopped, the people who died needed a place to be buried. They were buried in big cemeteries, which are places where dead people are laid to rest. These cemeteries were very big because so many people had died.
The title of the book, Les grands cimetières sous la lune, means "the big cemeteries under the moon". It is a sad and poetic title that describes the big cemeteries where many people were buried in this country long ago.
The book talks about the struggles and the experiences of the people who lived through this difficult time. It is an important book that teaches us about the history of this country and the people who lived there.
