In eastern Bosnia the tide of war has turned.
Serb villages are burning, roads are unsafe and more Serb soldiers are dying than ever before.
Columns of smoke rise above the Drina river valley, the graveyard in Zvornik has overflowed and Bosnian Muslims are on the offensive. Black-clad families march to Zvornik's cemetery to bury their sons. Fighters speed past in lorries mounter with anti-aircraft guns. They call themselves the Legion of Death. The tump of artillery can be heard around Zvornik.
