The war started for real in Bosnia right around this time 20 years ago. (Watch that BBC documentary I mentioned below for the complete story.)
The remains of war in Sarajevo are still quite visible. Walking the streets and looking at the hills above the city, you can imagine how it played out. Basically the might of the former JNA army in the hands of the Serbs rained hellfire from the surrounding mountain tops on a mostly civilian population below. For four years. A terrible story.
