Four battles almost razed this place to the ground, leaving only the wall foundation. A total of 500,000 British soldiers were buried here to guard the place. People have been discussing how it all started and how it ended. In the research, there are more than 7000 books about why the war started. No matter how it started at first, the hatred in it must be deeply rooted anyway.
