On the night of September 11, 2012, the American diplomatic mission at Benghazi, Libya, came under ferocious attack by a heavily armed group of Islamic terrorists. The prolonged fire fight, and the attack hours later on a nearby CIA outpost, resulted in the deaths of four Americans, including the American ambassador to Libya. After the fall of Qaddafi, Benghazi was transformed into a hotbed of fundamentalist fervour and a den of spies for the northern half of the African continent. Moreover, it became the centre of gravity for terrorist groups strategically situated in the violent whirlwinds of the Arab Spring. On the eleventh anniversary of the 9/11 attacks, a group of heavily armed Islamic terrorists had their sights set on the U.S. presence in the city. Based on the exclusive cooperation of eyewitnesses and confidential sources within the intelligence, diplomatic, and military communities, Fred Burton and Samuel M. Katz reveal for the first time the terrifying twelve-hour ordeal confronted by Ambassador Christopher Stevens, Sean Smith, his Diplomatic Security (DS) contingent, and the CIA security specialists who raced to rescue them.
