Someone gave the order to send a team of eight Marines and a Libyan security outfit from Tripoli to evacuate the personnel from the "annex" too. Initially it was reported that those Marines were ambushed at a staging area (a "farm") and two Marines were killed there. No further word on that. Other reports say the Marines fought at the "annex" and at least one was knocked off of a roof by a mortar round but no word that it killed him.
It was too little and there is no indication that 0bama had anything to do with it. His subsequent two weeks of bald-faced lying puts anything he says about it in doubt.
