On the evening of September 11, 2012, militants launched a coordinated assault on the U.S. diplomatic compound and CIA annex in Benghazi, Libya, resulting in a prolonged firefight.
During the attack on the Benghazi compound, U.S. Ambassador Christopher Stevens died of smoke inhalation after the building was set on fire.
CIA security contractors, including those portrayed in the movie, responded to the attack to defend the annex and attempt to rescue survivors.
Tyrone Woods and Glen Doherty, former Navy SEALs and CIA contractors, were killed defending the CIA annex during the attack.
