The Association for Diplomatic Studies & Training just posted, on the reopening of the US Embassy in Mogadishu, an oral history titled "Evacuating Somalia" in 1991 by Ambassador James K. Bishop.
Ambassador Bishop provided this oral history in November 1991. He describes the evacuation of the US embassy in Mogadishu in January 1991 by US military assets after the fall of Somali President Siad Barre and as the embassy compound was being overrun.
