ON BLOODY SUNDAY: A New History of the Day and Its Aftermath by Those Who Were There

In January 1972, soldiers from Britain's 1st Battalion Parachute Regiment opened fire on a peaceful civil rights march in Derry, Northern Ireland, leaving 13 dead and 18 injured. In 2010, Lord Saville found the British army fired first, and that most victims were either shot in the back while running away or helping someone in need. Seven of those killed were teenage boys.
