This photo was supplied to the Post by a Khmer Rouge defector who said it was taken by a KR general not long before Ta Mok was arrested in 1999. The man on Ta Mok's right was identified as Fu Xuexhang, China's Ambassador to Thailand accredited in 1997 and previously to Cambodia, and the woman on the right as Madame Chang, seen that year at the Chinese Embassy in Phnom Penh.

Thousands of others forced to walk for miles toward Thailand, with little or no food,
many perishing along the way.
** 1978: After Vietnamese invasion became Supreme Military Commander of remnants
of KR in Anlong Veng.
** By 1983: In Anlong Veng. His hatred of the Vietnamese had become paramount and
he claimed the deaths under Pol Pot were "done by Vietnamese agents."

other reports say land mine.
** By the end of the 1980s, an estimated 80 percent of Mok's troops were new recruits
who had not served in the DK regime.

claimed he remarried a KR commander's widow and had a child.
** 1992: Reinforced as KR's strongest military commander when Son Sen was demoted
and his troops handed over to Mok. Mok almost certainly remained loyal to Pol Pot
** 1996: dispatched with Son Sen and Nuon Chea to Pailin to quell breakaway revolt
led by Ieng Sary, and possibly to kill Sary. On return Pol Pot blamed Ta Mok for
failing to solve the situation. Pot tried to institute his own military structure,
starting to replace Mok loyalists. He may have tried to have Mok killed in late 1996.
** (c)1996: Like Sary, Mok began to favor integration with the Phnom Penh government,
while retaining considerable autonomy. Supported talks with Funcinpec commanders.
Ta Mok, center, at the wedding of his daughter and son-in-law, (on his left) probably in Thailand.

cadre about executing Pol Pot. Becomes new "Brother No 1".
** July 25 1997: Organised show trial of Pol Pot. Later Ta Mok and Pol Pot were interviewed
separately by Nate Thayer. Unrepentant, Mok chuckled as he debated whether the KR
killed millions of people or just "hundreds of thousands". Claimed he had
only killed Vietnamese.

because he considered Hun Sen "Vietnamese".
