September 7 / Skala Sykaminias, Greece — The Syrian refugee migration had reached a crisis, and the editors decided we should go to Europe. This is history; it’s an honor to document our world. We got a flight from Athens to Lesbos and had an hour-plus drive to the shores they were landing on. We saw this boat pull in; it was immediate chaos, everybody scurrying out and trying to get to shore. In the midst of it all, I turned around and saw this peaceful moment behind me, these two gentlemen praying on the beach.
