>...The next essay deals with one of the most infamous chapters in
the history of the CPP. The essay "When the Revolution Devours Its
Children Before Victory: Operasyong Kampanyang Ahos and the Tragedy
of Mindanao Communism" details the operation staged by the CPP
Mindanao Commission codenamed Operasyong Kampanyang Ahos (Kahos) to
weed out alleged military agents who infiltrated the New People’s
Army and the National Democratic Front. The operation that started
as a systematic investigation in Mindanao turned out to be a bloody
affair to ferret out and eliminate suspected and real spies.
Abinales wrote that the killings cost the CPP dearly. Instead of
eliminating military spies, the victims of Kahos were loyal cadres,
guerrillas, and activists who disagree with Party policies. Within a
six month period, 950 cadres, guerrillas and activists were
executed. News about the executions resulted in the lost of over 50
percent of its mass base nationwide due to resignation, surrender or
absence without official leave (AWOL).
