The NATO-led peacekeeping Kosovo Force (KFOR) began entering Kosovo

On 12 June, after Milošević accepted the conditions, the NATO-led peacekeeping Kosovo Force (KFOR) began entering Kosovo. KFOR had been preparing to conduct combat operations, but in the end, its mission was only peacekeeping. It was based upon the Allied Rapid Reaction Corps headquarters commanded by then Lieutenant General Mike Jackson of the British Army.
