He took office on 1 April 1975, when a tearful
Lon Nol left 'temporarily' with his entire family for
Bali in
Indonesia after an invitation from his friend,
Indonesian President Suharto. Khoy's time in office was short. He left
Phnom Penh together with American Ambassador
John Gunther Dean aboard a
CH-53 helicopter during the evacuation of American embassy staff and civilians, dubbed
Operation Eagle Pull on 12 April, just five days before
Phnom Penh fell to the
Khmer Rouge led by their new organization as
Angkar. ==Death==
