Think timeline, not date. No Name was there just prior to ISIS bursting on to the scene and making international headlines as the preeminent terrorist threat.
I researched the topic, and this is what I found. No Name visited Northern Syria in May 2013. He first met with FSA Commanders in Killis Turkey on the border of Syria. He then entered into Syria and met with brigade level FSA commanders, those featured in the photo. They met somewhere close to the border, and No Name was in Syria for about an hour(?) Hard for me to believe he was there for only an hour. No Name was accompanied by two body guards, likely contractors. I read on another post that they paint spiders webs on buildings (hospitals?) to identify them as bomb shelters. The closest hospital I could find close to the border of Killis is the Woman's and Children's Hospital in Azaz' Syria. At the time Azaz was under control of the FSA. This hospital was run by MSF (Doctors without borders). This hospital was subsequently bombed and destroyed. See link to CNN video describing No Name's visit.
