One of the most severely wounded survivors of the Benghazi terror attack, Diplomatic Security agent David Ubben, risked his life to help save his fellow Americans, and is still being treated at Walter Reed medical center to this day, Fox News has learned.
Fox News is the first news organization to make direct contact with Ubben -- who has had multiple surgeries at Walter Reed to save his right leg, which was badly wounded in the Sept. 11 attack.
Fox News has also learned new details about Ubben's heroic actions on the night of the attack, including fighting alongside the former Navy SEALs who were later killed.
The Diplomatic Security agent, earlier in the night, helped recover the body of Foreign Service Officer Sean Smith, going back into the smoke and flames at the Benghazi consulate multiple times until he found Smith, whom he believed to be already dead from smoke inhalation.
Fox News is not publishing his photo in full, out of respect for Ubben's request for privacy as he remains focused on his family and his recovery alongside America's wounded warriors from Iraq and Afghanistan.
Hearing of the details from Fox News, Sean Smith's mother Pat said she hopes one day to meet Ubben in person.
"Thank you very much for what you've done," Pat Smith said, her voice filled with gratitude but also anger. "Why couldn't the government have done the same thing? I think (Ubben) is a hero. He absolutely is a hero along with the two Seals that got it. There's no reason for all these people to die."
Ubben also went back into the smoke-and-flame filled Benghazi consulate several times searching for Ambassador Chris Stevens, but could not find him.
Sources tell Fox News that during the second wave of the attack, Ubben was on the roof of the CIA annex -- along with former Navy SEALs Tyrone Woods and Glen Doherty -- defending the compound. It was a harrowing scene as dozens of militants attempted to swarm the barriers.
In another sign the attacks were pre-meditated, three mortar rounds rained down on the compound. The first fell short of the annex, about 50 yards away, but the subsequent mortar rounds were direct hits.
Both Woods and Doherty were killed, with the mortar shredding Ubben's right leg.
