A little history/geography quiz

[CGM]

Anyways, the event I am looking for is the city of Nanjing China, where the civilians were slaughtered by Japanese soldiers prior to the outbreak or WWII. The event is known as "The Rape of Nanjing (Nanking)" There is some extensive and unpleasant video dicumentary available on Youtube. Be forewarned, it is not pretty.

I only found out about this a couple years ago, it is not as well known as you might expect
