WASHINGTON — Two of the four US deaths in Benghazi might have been prevented, military leaders say, if commanders had known more about the intensity of the sporadic gunfire directed at the CIA facility where Americans had taken refuge and had pressed to get a rescue team there faster.
Senior military leaders have told Congress in closed-door testimony that after the first attack on the main US diplomatic compound on Sept. 11, 2012, they thought the fighting had subsided and the Americans who had fled to the CIA base about a mile away were safe. In fact, they were facing intermittent small arms fire and rocket-propelled grenades around midnight and had returned fire. Then the attackers dispersed.
Hours later, at first light, an 11-minute mortar and rocket-propelled grenade attack slammed into the CIA annex, killing security contractors Tyrone Woods and Glen Doherty.
In hindsight, retired General Carter Ham, then head of the US military command in Africa, said he would have pressed Libyan contacts in the defense ministry and other officials to help speed up the evacuation of Americans from Benghazi.
Also, a special operations team that had been dispatched from Croatia to Sicily after the first attack might have made it to Benghazi, if a host of variables were ideal — a quick departure, wind direction and speed, and an unobstructed runway to land a US aircraft.
Ham said ‘‘in a perfect world, with no other disruptions or distractions,’’ it could have happened.
As it turned out, a six-man security team, including Special Forces personnel that arrived at Benghazi airport at 1:30 a.m., was held up there for hours by Libyan militia.
‘‘In my view, that time delay, that inability of the team to get off of the Benghazi airport and get to the annex and back I think allowed sufficient time for the second attack to be organized and conducted,’’ said Ham, who was in Washington at the time of the attacks.
Two House panels — Armed Services and Oversight and Government Reform — interviewed nine military officers earlier this year, and the testimony was released this week.
The family of Doherty, a former Navy SEAL and Winchester native, had no comment on the military leaders’ testimony.
For the military, the fog of war shrouded Benghazi even before the night of Sept. 11.
The first assault, about 9:40 p.m. local time, which killed Ambassador J. Christopher Stevens and communications specialist Sean Smith, was the first news to some military leaders that the United States even had a diplomatic mission in the Libyan port city — and that Stevens was there even though Benghazi was considered a dangerous, near-lawless city after the fall of dictator Moammar Khadafy.
In a very short time, many in the military, including Ham, would then learn about the CIA annex.
In his testimony, Ham said he was certain that someone in his command knew of the existence of the facilities in Benghazi, but he acknowledged that the crisis was ‘‘not the ideal time to become aware of such facilities.’’
‘In my view, that time delay, that inability of the team to get off of the Benghazi airport and get to the annex and back I think allowed sufficient time for the second attack to be organized and conducted.’
Throughout the night, the information relayed to military officers in Tripoli, up the chain of command to AFRICOM headquarters in Stuttgart, Germany, and the Pentagon in Washington was incomplete and often contradictory. And that complicated efforts to mobilize personnel and aircraft to get Americans out of Libya.
‘‘Omniscience is for God only,’’ said a member of the US Army who was operations director for the Special Operations Command Africa, and whose name was omitted from the testimony.
After the first attack, Ham and other military leaders were focused on a potential hostage situation, unaware that Stevens was already dead from smoke inhalation. They were under the impression that the Americans at the annex were safe, and none of the information they received suggested otherwise.
Vice Admiral Charles ‘‘Joe’’ Leidig Jr., who was Ham’s deputy, said the Americans were not requesting military reinforcements to respond to the sporadic gunfire, but rather were seeking a plane to get out.
‘‘Once that indirect fire was over, they said we’re going to get out of this annex, we’re going to get to the Benghazi airfield, and now what they wanted was lift capability at Benghazi airfield,’’ Leidig said.
A US defense attache in Tripoli, who was relaying information up the chain of command that night, said he did not learn of the nighttime gunfire until a day or two later.
Americans at the CIA base were confident they could deal with the gunfire.
The intelligence official who was the chief of base told the Senate Intelligence Committee in December 2012 that ‘‘until the mortar attack, we were pretty comfortable that we could stave off any type of ground assault on the annex.’’
