On September 11, 2012, militants attacked the U.S. diplomatic compound and a nearby CIA annex in Benghazi, Libya. This is the basis of the film.

A small team of private security contractors defended the CIA annex, as depicted in the film.

The contractors did repel the initial attack on the diplomatic compound, but the film may exaggerate their success and downplay the Libyan guards' role.

Ambassador J. Christopher Stevens died during the attack. The film portrays his death, though the exact circumstances remain unclear.

The CIA annex was indeed besieged by militants for hours, with intense firefights.

A mortar attack on the annex killed two contractors, Tyrone Woods and Glen Doherty, as shown in the film.

The film depicts a CIA officer delaying the contractors' response to the initial attack. Whether a 'stand down' order was given is highly controversial and debated.

While requests for military support were made, the response was delayed. The reasons for the delay remain a point of contention.

While the contractors undoubtedly acted bravely, the film arguably focuses on their actions at the expense of the broader context and other individuals involved.

The attackers are portrayed as generic militants. The film doesn't delve deeply into their motivations or affiliations, which were complex in reality.

The film focuses on the immediate events of the attack and largely avoids delving into the broader political context in Libya at the time.

13 Hours' captures the intensity of the attack and the heroism of the contractors, but it also simplifies some aspects and takes a stance on disputed events, making its overall accuracy debatable.
