Summary
The mass killings in Bangladesh (then East Pakistan) in 1971 vie with the annihilation of the Soviet POWs, the holocaust against the Jews, and the genocide in Rwanda as the most concentrated act of genocide in the twentieth century. In an attempt to crush forces seeking independence for East Pakistan, the West Pakistani military regime unleashed a systematic campaign of mass murder which aimed at killing millions of Bengalis, and likely succeeded in doing so.
The gendercide against Bengali men
The war against the Bengali population proceeded in classic gendercidal fashion. According to Anthony Mascarenhas, "There is no doubt whatsoever about the targets of the genocide":
They were:
(1) The Bengali militarymen of the East Bengal Regiment, the East Pakistan Rifles, police and para-military Ansars and Mujahids.
(2) The Hindus -- "We are only killing the men; the women and children go free. We are soldiers not cowards to kill them ..." I was to hear in Comilla [site of a major military base] [Comments R.J. Rummel: "One would think that murdering an unarmed man was a heroic act" (Death By Government, p. 323)]
(3) The Awami Leaguers -- all office bearers and volunteers down to the lowest link in the chain of command.
(4) The students -- college and university boys and some of the more militant girls.
(5) Bengali intellectuals such as professors and teachers whenever damned by the army as "militant." (Anthony Mascarenhas, The Rape of Bangla Desh [Delhi: Vikas Publications, 1972(?)], pp. 116-17.)
Mascarenhas's summary makes clear the linkages between gender and social class (the "intellectuals," "professors," "teachers," "office bearers," and -- obviously -- "militarymen" can all be expected to be overwhelmingly if not exclusively male, although in many cases their families died or fell victim to other atrocities alongside them). In this respect, the Bangladesh events can be classed as a combined gendercide and elitocide, with both strategies overwhelmingly targeting males for the most annihilatory excesses.
Atrocities against Bengali women
As was also the case in Armenia and Nanjing, Bengali women were targeted for gender-selective atrocities and abuses, notably gang sexual assault and rape/murder, from the earliest days of the Pakistani genocide. Indeed, despite (and in part because of) the overwhelming targeting of males for mass murder, it is for the systematic brutalization of women that the "Rape of Bangladesh" is best known to western observers.
In her ground-breaking book, Against Our Will: Men, Women and Rape, Susan Brownmiller likened the 1971 events in Bangladesh to the Japanese rapes in Nanjing and German rapes in Russia during World War II. "... 200,000, 300,000 or possibly 400,000 women (three sets of statistics have been variously quoted) were raped. Eighty percent of the raped women were Moslems, reflecting the population of Bangladesh, but Hindu and Christian women were not exempt. ... Hit-and-run rape of large numbers of Bengali women was brutally simple in terms of logistics as the Pakistani regulars swept through and occupied the tiny, populous land ..." (p. 81).
Typical was the description offered by reporter Aubrey Menen of one such assault, which targeted a recently-married woman:
Two [Pakistani soldiers] went into the room that had been built for the bridal couple. The others stayed behind with the family, one of them covering them with his gun. They heard a barked order, and the bridegroom's voice protesting. Then there was silence until the bride screamed. Then there was silence again, except for some muffled cries that soon subsided. In a few minutes one of the soldiers came out, his uniform in disarray. He grinned to his companions. Another soldier took his place in the extra room. And so on, until all the six had raped the belle of the village. Then all six left, hurriedly. The father found his daughter lying on the string cot unconscious and bleeding. Her husband was crouched on the floor, kneeling over his vomit. (Quoted in Brownmiller, Against Our Will, p. 82.)
"Rape in Bangladesh had hardly been restricted to beauty," Brownmiller writes. "Girls of eight and grandmothers of seventy-five had been sexually assaulted ... Pakistani soldiers had not only violated Bengali women on the spot; they abducted tens of hundreds and held them by force in their military barracks for nightly use." Some women may have been raped as many as eighty times in a night (Brownmiller, p. 83). How many died from this atrocious treatment, and how many more women were murdered as part of the generalized campaign of destruction and slaughter, can only be guessed at (see below).
