11 December 1981 was the second day of the three-day massacre of the village of El Mozote, El Salvador.
Beginning on 10 December (the official date of remembrance in that Central American nation), US-trained and armed Atlacatl Battalion of the Salvadoran armed forces occupied that village. The following day, it tortured, raped and murdered the 900+ unarmed people of El Mozote. This was part of a larger military operation called Operación Rescate.
To date, no-one has been brought to trial for that atrocity. You may read more about it (in Spanish) here: http://verdaddigital.com/index.php/nacionales/14333-masacre-el-mozote-cumple-hoy-33-anos-y-continua-en-la-impunidad.
During my first trip to El Salvador shortly after the peace accords were signed, I spent time in Morazán Department. I interviewed people in several villages – including Perquín, Segundo Montes and, yes, El Mozote – about their experiences during the civil war.
I was one of the first to reveal that El Mozote was being repopulated. In fact, I arrived on foot to that village just as the returnees were cleaning the ruins, to begin anew.
This is the poem I was compelled to write at that moment, sitting in the scant shade of the silhouette statue.
And this is a report from a few years ago about the refound village: http://news.discovery.com/history/videos/history-el-salvador-massacre-revisited.htm
