following hours, after intense shelling by ERC 90 Sagaie armoured vehicles, the French stormed the post, killing four Serbs and capturing four others. Two French soldiers were killed and 17 were wounded. At 12 o'clock, the Bosnian Serb radio broadcast that General Mladić had ordered to On the 30 May, Ratko Mladić phoned Rupert Smith and agreed to not place Blue Helmets hostages in chains, but to merely "bring" them on strategic sites. He also demanded apologies for the death of the four Serbian soldiers killed by the French at Vrbanja bridge, threatening to "be unable to guarantee the safety" of the UN forces in Goražde. The fall of Srebrenica On 12 July 1995 UNPROFOR failed to deter the Bosnian Serb attack on Srebrenica because they were not able to sufficiently reinforce the Dutch battalion in place, and the city was subsequently overrun. When the dual key practices effectively prevented any serious air support from materialising, the Dutch began evacuating women and children. The Serbs held the Muslim men and massacred thousands of them. The safe area of Zepa also fell to Bosnian Serbs on 25 July. The events in Srebrenica led to the Peacekeeping Best Practices Unit (PBPU) report NATO initiated "Operation Deliberate Force" on 30 August 1995 in response to further provocations by Serb forces. At this point, UNPROFOR had become "militarily engaged" with NATO against the Bosnian Serb Army. NATO and UNPROFOR were increasingly difficult to separate by autumn 1995, both in terms of policy and actions taken on the ground. In retaliation for the NATO bombings, the Serbs proceeded to retrieve their confiscated heavy weapons from the UN-controlled concentration points by force. The peace-keepers, massively outnumbered, were forced to surrender after brief, symbolic firefights. In several instances, Blue Helmets were surrounded in weapon storage areas by numerically superior Serbian forces. General Hervé Gobillard, commanding officer for UN troops in Sarajevo, stated that the peacekeepers were "merely limited in their movements, yet [had] arms, ammunition, food for many days, and strict orders to defend their positions", but in the light of the hostage-takings, concerns were raised and the UN-led bombing stopped. Also, Serbian retaliations against civilians stemming from the bombings caused 70 dead and 150 wounded in Tuzla, and 5 dead in Goražde. Later, on a winter day, British UN troops carrying sidearms were confronted by General Mladić skiing down the piste at Sarajevo's former Olympic skiing
