The phrase became popular after the release of a book titled Black Hawk Down: A Story of Modern War. The book chronicles the U.S. military attempt of 1993 to capture a warlord, Mohamed Farrah Aidid, in Mogadishu, Somalia, and the intense battle that resulted between U.S. forces on duty with the United Nations against local militia and citizens.
