Early on 11 June 1999, a column of about 30 Russian armoured vehicles carrying 250 Russian troops, who were part of the international peacekeeping force in Bosnia, moved into Serbia. At 10:30 this was confirmed by
Supreme Headquarters Allied Powers Europe and by pictures from
CNN which showed that the Russians had hastily painted "KFOR" in white letters on their vehicles where they had previously been "
SFOR". It was assumed that the column was heading for Pristina and
Pristina International Airport ahead of the arrival of NATO troops. Upon hearing of the deployment, American NATO Supreme Allied Commander Europe General Wesley Clark called NATO Secretary-General
Javier Solana and was told "you have transfer of authority" in the area. Clark then provisionally ordered a contingent of British and French paratroopers to be flown in by helicopter to seize the airport by force. Staff officers had grave concerns that helicopters might be fired on by Serb forces and that entering Kosovo before the agreed time might cause the Serbs to pull out of the agreement. If the airborne force got into trouble it would have been very difficult to reach them overland through the mountainous country where bridges and tunnels were known to be prepared for demolition. As this operation would have been outside the newly signed agreement for NATO forces to move into Kosovo the following day, national governments had the right to withdraw their own forces and the French government pulled its battalion out. British paratroopers sat by
Boeing CH-47 Chinook helicopters in a hot cornfield for most of the afternoon before standing down to prepare for the following day's move into Kosovo. Jackson flew by helicopter to Pristina in the evening to hold a press conference, then went to meet General
Viktor Zavarzin, who commanded the small Russian force. Sheltering from heavy rain in the wrecked airport terminal, Jackson shared a flask of whisky with Zavarzin, leading to a warming of relations. That evening Clark was still concerned with the possibility of more Russian troops being flown in through NATO-controlled
airspace. When again directly ordered to block the runway, Jackson suggested that British tanks and armoured cars would be more suitable, in the knowledge that this would almost certainly be vetoed by the British government. Clark agreed. Jackson was ready to resign rather than follow Clark's order. The British Ministry of Defence authorised British force commander
Richard Dannatt to use 4 Armoured Brigade to isolate the airfield but not to block the runways. Negotiations were conducted throughout the stand-off during which Russia insisted that its troops would only be answerable to Russian commanders and that it would retain an exclusive zone for its own peacekeepers. NATO refused these concessions, predicting that it would lead to the partition of Kosovo into an Albanian south and a Serbian north. Both sides eventually agreed that Russian peacekeepers would deploy throughout Kosovo independently of NATO. ==Aftermath==
