Bilanggo is the diary of a decade behind bars. William Pomeroy and his wife Celia Mariano, like hundreds of other communists and militants, were sent to prison in the early 1950s for participating in the Huk guerrilla struggle for national liberation. Pomeroy's personal narrative of the armed struggle, The Forest, has become a classic. Bilanggo is its sequel, written with the same immediacy and power. It describes how the political prisoners endured stretches of solitary confinement, were denied basic amenities, and witnessed horrific outbursts of violence between warring prison gangs. But above all, it depicts how they refused to be broken, or to give up their vision and ideals.
