Unable to breach the safe room, the attackers set the building on fire hoping to burn the men out . Wickland is able to escape but loses both Stevens and Smith . At the Annex, the GRS team desperately wants to go to the compound to help, but the Chief refuses, fearing that the team's departure would expose the Annex . However, the team dispatches to the compound and meets up with the DS agents . Silva and Woods go into the building to try to find Stevens and Smith, but are only able to find Smith's body . The DS team from the compound retreats to the Annex; but after Wickland goes in the wrong direction, they are followed back to the Annex .

The only help they can get is from Glen "Bud" Doherty, a GRS officer in Tripoli, who forms a team including two Delta operators that fly to Benghazi after several delays . Meanwhile, the GRS team fends off the militants as they try to breach the Annex perimeter . After repelling the largest attack wave, the Annex receives word from ISR that help is en route . </P> <P> The Tripoli GRS reinforcements arrive and begin preparing the CIA and DS staff to depart for the airport . The militants launch a mortar attack in which Ubben and Geist are wounded; Geist's left arm is partially severed . Woods rushes to aid Geist and is killed by another mortar round . Doherty is also killed when a third mortar detonates directly in front of him . </P> <P> With the GRS team compromised, and the Annex now vulnerable, the remaining GRS operators watch as a convoy of vehicles rolls toward the Annex .

They also find out that Stevens was found behind the compound, but was pronounced dead at the hospital . </P>
