An email hidden from public view for three years reveals a rescue attempt was interrupted. The military offered to deploy Special Forces to Benghazi during the assault, long before the attackers killed CIA contractors and former Navy Seals Glen Doherty and Ty Woods. Three and a half hours into the eight-hour long siege, the military's Chief of Staff Jeremy Bash emails top State Department officials: "we have identified the forces that could move to Benghazi. They are spinning up as we speak. They include a SOF [Special Operations Forces] element that was in Croatia."
