On September 11, 2012, one year ago, a terrorist attack on the U.S. consulate in Benghazi, Libya, claimed the lives of four Americans — including a U.S. ambassador.

The next day, President Barack Obama vehemently declared the U.S. would bring those responsible to justice.

“Make no mistake,” the president firmly said. “We will bring justice to the killers who attacked our people.”

Today, on the one year anniversary, those who perpetrated the act of terrorism have not been held accountable and many questions remained unanswered.

TheBlaze has assembled a timeline detailing how the events first unfolded in Benghazi — and now on the political battlefield in Washington, D.C.

Timeline of Terror: Benghazi One Year Later

September 11, 2012

The day is quiet. There are no signs of the impending attack.

U.S. Ambassador Chris Stevens retires to his room on the American diplomatic compound in Benghazi at around 9 p.m., after escorting a Turkish diplomat outside to the main entrance of the consulate.

According to the Associated Press (AP), at that time “the situation is calm” and “there are no protests.” There is no sign of a spontaneous protest against a newly-released American-made movie attacking Islam.

Then, about an hour later, the attack comes.

According to the AP, roughly 150 “bearded gunmen” surround the consulate, showering it in a barrage of automatic weapons fire and employing the use of rocket-propelled grenades.

Phone calls requesting security reinforcements are made to officials in D.C., the embassy in Tripoli, the Libyan authorities and a U.S. quick reaction force about a mile away.

The attackers breach the compound, however, before any help arrives.

They set fire to the main consulate building. Stevens, along with Foreign Service Officer Sean Smith inside, die of smoke inhalation.

Watch an illustrated summary of events: 

Eventually, a six-person reaction team arrives on the scene with about 60 Libyan security officers. They attempt to secure a perimeter, but can’t and decide to evacuate the consulate.

As they evacuate, the group sustains heavy machine gun fire and has grenades lobbed at their vehicles. At one point, the team even drives into opposing traffic, before finally arriving at another compound.

A team of security officials from the embassy in Tripoli also meets them there.

At around 4 a.m., the compound the consulate staff has retreated to comes under attack. The building is hit by mortar fire and two former U.S. Navy Seals, Glen Doherty and Tyrone Woods, are killed.

At this point, the decision is made to evacuate the city entirely.

September 12, 2012

Obama addresses the nation from the Rose Garden and condemns the “outrageous and shocking attack” in the “strongest terms.”

“I’ve also directed my administration to increase our security at diplomatic posts around the world,” Obama says. “And make no mistake, we will work with the Libyan government to bring to justice the killers who attacked our people.”

“No acts of terror will ever shake the resolve of this great nation, alter that character, or eclipse the light of the values that we stand for,” he continues. “Today we mourn four more Americans who represent the very best of the United States of America. We will not waver in our commitment to see that justice is done for this terrible act. And make no mistake, justice will be done.”

Clinton reportedly references the attack as an “attack by a small and savage group.”

September 14, 2012

The bodies of Stevens, Smith, Woods and Doherty are returned to the U.S.

Smith’s mother would later say that Obama, Clinton, and then U.S. Ambassador to the United Nations Susan Rice told her “nose-to-nose” that day that the attack was the result of an anti-Muslim YouTube video:

September 16, 2012

Susan Rice says on television the attack began as a spontaneous protest, “based on the best information we have to date,” adding no evidence gathered shows it was premeditated or coordinated.

September 18, 2012

White House Press Secretary Jay Carney says the attack is still under investigation, but says there is no evidence pointing to an organized terrorist attack.

Later that night, Obama explains to David Letterman on TV that the anti-Muslim movie inflamed Muslims worldwide, giving “extremists and terrorists” an “excuse” to attack our embassies, “including the one, the consulate in Libya.”

September 20, 2012

Obama continues to point to the anti-Islam film as the cause of the attack.

“What we do know is that the natural protests that arose because of the outrage over the video were used as an excuse by extremists to see if they can also directly harm U.S. interests.”

Carney also says “what happened in Benghazi was a terrorist attack.”

Clinton, however, argues the root cause behind the attack is irrelevant.

“We had four dead Americans,” she says. “Was it because of a protest or because of guys out for a walk one night and decided to go kill some Americans? At this point what difference does it make, Senator?”
