They were soldiers of their own country, Black Mauritanians of the Halpulaar community, arrested in the weeks before during a wave of detentions. Accused of plotting against the government, they were taken to the base at Inal, and there, in the dark, they were tortured and hanged, one after another, by other soldiers. At least 28 died that night and were buried in a mass grave. The timing was its own cruelty: the killings fell on the celebration of the nation's freedom from colonial rule, as though the executions were meant as some grotesque observance of the date. These were not statistics. They were husbands, sons, and fathers, men who had put on the uniform of Mauritania and were killed by the army they served.

Inal was not an isolated horror but the sharpest edge of a larger one. Between late 1990 and early 1991, Mauritanian authorities arrested roughly 3,000 Black soldiers on accusations of plotting a coup, and by credible estimates between 500 and 600 of them were summarily executed after torture and secret detention. The killings belonged to a broader campaign of state violence and expulsion directed at Afro-Mauritanians across the late 1980s and early 1990s, a period Mauritanians refer to with painful understatement as the passif humanitaire, the humanitarian liability. Inal became its most enduring name, the place where the machinery of that terror is remembered most clearly, because the survivors and the bereaved would not let it be forgotten.

Justice never came. In June 1993 the government passed an amnesty law, Act No. 93-23, that shielded the members of the security forces from prosecution for the crimes of those years. It granted, in effect, immunity for torture, enforced disappearance, and extrajudicial killing, and closed the door on the courts before the families could reach them. International bodies, the African Commission on Human and Peoples' Rights and United Nations experts among them, have judged the law incompatible with international standards and condemned the absence of any genuine investigation. For the survivors, the law transformed an open wound into an official silence, the killers protected by the same state that had ordered the deaths.

Every year, on the anniversary, survivors and victims' families gather to read the names and demand the truth, and some have been arrested for doing so. They are widows, orphans, and former comrades who lived through the violence and stayed, still asking for acknowledgment, for the recovery of remains, for accountability that the amnesty law denies them. Their persistence is the real monument here, more durable than anything built of stone. Inal the town goes on, quiet beside its railway in the hard light of the Sahara. But its name now belongs to memory, to the 28 men who died at its base, and to the people who keep insisting, decade after decade, that they mattered.
