Mount Igman became in the course of the 1991-95 conflict suddenly an area of major strategic importance as part of the 1992-1995 Siege of Sarajevo. The predominantly Bosniak villages of Hrasnica and Butmir held out as an ARBiH stronghold between the BSA-held villages of Ilidža and Vojkovići, forming a corridor connecting the slopes of Mt Igman with the UN-controlled airport of Sarajevo. After the completion of the Sarajevo Tunnel under the airport in July 1993, the small unpaved forest road passing over Mt Igman became the sole important supply road into the besieged city. The ARBiH-controlled central plateau of Igman came under increased Serb military pressure when the suspicion became stronger that the area had become a major logistical artery of the besieged city. A major BSA offensive started July 1993 and on August 4, 1993 Serb forces captured part of the Igman supply road. The BSA advance was stopped under threat of NATO airstrikes. The area was declared a Demilitarized Zone (DMZ) by the UN after the BSA retreated and UNPROFOR units were stationed on Igman and nearby Bjelašnica. The supply road into Sarajevo was agreed to be used for humanitarian goods only, but ARBiH logistical activity on the road and through the tunnel continued nevertheless. Discussion about real or alleged reluctance to withdraw ARBiH forces from the DMZ was a growing issue between UNPROFOR Commander General Rose and ARBiH Commander General Delić, with BSA Commander Mladić waiting for an opportunity to close the gap. Trucks on the Igman supply road's narrow last stretch descending the steep north-eastern slope became fully exposed to fire from BSA artillery positions in Ilidža and Vojkovici. Meanwhile, the ARBiH units remaining on the plateau were formally restricted to R&R activities, notably resulting in the building of the Igman Dzamija, a wooden mosque in the forest, still much frequented today. The Igman supply road remained the almost exclusive supply route into Sarajevo until the end of the war. It was also the only entry and exit road for the Bosnian political leadership. Bosnian president Alija Izetbegović and foreign secretary Muhamed Sacirbey traveled this road. Foreign negotiators tended to avoid the road as it was often described as the most dangerous road in Europe. Forced by a Serb blockade of the Sarajevo Airport, on August 19, 1995, a US Peace Mission headed by Richard Holbrooke took this road in order to reach Sarajevo for a meeting with the Bosnian presidency. Holbrooke decided to sit with General Wesley Clark in a Humvee, while the other members of the delegation travelled in a French UNPROFOR Renault VAB Armored Personnel Carrier. At a particular exposed and narrow point -now marked by a French memorial plaque- the French APC went over the edge and rolled and tumbled down some 400 metres. US Diplomats Robert Frasure, Nelson Drew and Joe Kruzel as well as the French Corporal-driver perished in the incident. The battered APC is still to be seen where it ultimately came to a halt - next to a memorial site for the victims. By mid-1995 the military situation became very tense again, and in August 1995 the BSA launched another offensive forcing UNPROFOR from the Bjelašnica ridge and advancing again towards Veliko Polje. After the second Markale shelling, on August, 30 NATO started Operation Deliberate Force, in which NATO aircraft engaged BSA Command & Control facilities and other targets. In conjunction with these attacks a Rapid Reaction Force consisting of units of the British 19th Reg. Royal Artillery, the French 2nd Legion Etranger d'Infanterie and the Dutch 1e Mortiercompagnie of the NL Marine Corps, was deployed on Igman with (RNLA) search radars and heavy artillery, engaging any actively firing BSA artillery installation around Sarajevo until 14 September 1995, when the NATO air strikes were suspended to allow the implementation of the withdrawal of BSA heavy weapons from the Sarajevo exclusion zone, effectively ending the Siege of Sarajevo. A number of memorials and war cemetery sites is found throughout the Igman plateau.
