Black Hawk Down: A Story of Modern War is a 1999 book by journalist Mark Bowden. It documents efforts by the Unified Task Force to capture Somali faction leader Mohamed Farrah Aidid in 1993, and the resulting battle in Mogadishu between United States forces and Aidid's militia. One of the key events is the downing of two United States UH-60 Black Hawk helicopters, from which the book derives its title, and the attempt to rescue their crews. United States forces included Army Rangers, 160th Special Operations Aviation Regiment, 10th Mountain Division, Delta Force and Navy SEALs, with United Nations peacekeeping forces also involved.
